ANGELUS – U10 Tourbillon Calaveras

ANGELUS – URBAN U10 Tourbillon Calaveras - Unique piece

From the earliest days of its conception, the master model U10 Tourbillon Lumière was imagined as a piece of mechanical art, paying tribute to some of the most influential and forward-thinking designers from the 60s and 70s, such as Dieter Rams and Achille Castiglioni.

Now, Angelus is pushing the envelope even further by integrating striking visual art into this singular watch.

With its unique design and especially its vitrine-type construction, the U10 offers an extraordinary platform to showcase not only its oversized tourbillon, but also miniature works of wearable art. As such, Angelus will take on different themes from various artistic movements and integrate them with its U10.

The first unique piece from this Angelus U10 art collection pays tribute to the old tradition of Mexican Calaveras. These are part of a very ancient tradition of memento mori. Since Ancient Rome, Memento mori has been an important part of ascetic disciplines as a means of perfecting the character by cultivating detachment and other virtues, and by turning the attention towards the immortality of the soul and the afterlife. Symbolic reminders of mortality, what could have been a better theme to ornate the tourbillon watch displaying dead beat seconds than a mementos mori?

The Calaveras are mainly used in the Mexican celebration of the Day of the Dead (Día de los Muertos), where people remember and honor those who have passed on with calaveras, poems and other forms of symbolism. Above all, it is a celebration of life and its transient nature.

The U10 Tourbillon Calavera is a unique piece in stainless steel,
which launches the Angelus U10 art collection.

A timepiece of glorious contrasts

Four years in the making, the U10 Tourbillon Calavera not only upholds the Angelus tradition of creating extremely inventive timepieces boasting finely-finished, in-house movements with long power reserves, it is also a timepiece of glorious contrasts.

On one hand the U10 Tourbillon Calavera is classic haute horlogerie. Its dead beat seconds complication – where the second hand advances in full steps of one second – derives from 18th-century pocket watches; the movement bridges and plates are in traditional nickel-silver that is bevelled and polished; and the traditional 2.5Hz / 18,000 vph of the screwed balance with Breguet-overcoil is a throwback to some of Angelus’ early pocket watches.

And yet, the modernist display, innovative engineering and state-of-the-art materials and finishing ensure that the U10 Tourbillon Calavera can equally be viewed as a paragon of cutting-edge, contemporary watchmaking.

Flying tourbillon on full show thanks to deconstructed movement and duplex case

The configuration of the manual-winding calibre is decidedly avant-garde, with the tourbillon positioned far outside of the movement, displayed alone as a dazzling mechanical sculpture in its own sapphire crystal vitrine.

The generously-proportioned – 62.75 mm x 38 mm x 15 mm – case, which took over two years to develop, features no fewer than seven sapphire crystals. All the crystals are bevelled, polished and subtly protrude from the case, creating expressive three-dimensionality.

Click, to see the large size. ▶ BIG FOTO

Four of these crystals – including one wrapping 90° over the end of the case – surround the tourbillon, allowing unfettered views to the beating heart of the timepiece. The large windows also let light flood in and shine a spotlight on this mechanical centrepiece. The vitrine aspect of the tourbillon space is cleverly enhanced by light-absorbing, matte black PVD finish on the interior walls encasing the tourbillon.

The stainless steel used to make the case is BO-988 specific steel. This annealed steel is of a higher quality than the usual 316L steel found in timepiece cases because it contains fewer impurities, is less liable to corrode and is more biocompatible. Its finer grain size allows for a better standard of polishing and higher level of finish.

State-of-the-art movement materials, long power reserve and high precision

With its generous 16.25 mm diameter, the hand-polished tourbillon cage is crafted from weight-saving stainless steel, while titanium has been chosen for the tourbillon bridge due to its strength and shock-absorbing qualities. The flying tourbillon configuration does not need an upper supporting bridge and offers unimpeded views to the top of the regulator. The combination of nickel-silver, titanium and stainless steel in a watch movement is unique and especially the magenta lacquer for the bridge of the tourbillon cage.

Supporting the two mainspring barrels (which are in series for better timekeeping precision) is a bridge featuring a high-tech laser-engraved, satin-finished, criss-cross pattern. The two ratchets are also laser-engraved and enamelled.

A large diameter one-minute tourbillon requires significant energy, which is amply supplied by the dual main spring barrels. When fully wound, the Angelus A100 calibre provides a very healthy 90 hours of optimal power. The two mainspring barrels are optimally sized in a special ratio for a flatter torque curve, which maximizes accuracy throughout for the full 90 hours.

Indications and displays

The hour and minute hands – brushed finished, rhodium-treated and filled with blue lacquer – are actually set into the concave dial made of grey-tinted sapphire. Like the interior of the tourbillon vitrine, the walls of the dial recess have also been bead-blasted to a matte finish and then black treated. Tiny holes drilled into the dial at 12, 3, 6 and 9 o’clock and filled with Super-LumiNova create bright white markers.

Click, to see the large size. ▶ BIG FOTO

In a neat touch highlighting the meticulous thought that has gone into every aspect of the U10 Tourbillon Calavera, the dead beat seconds hand rotating flush with the top of the dial features a counter weight on its short end. Each passing second marked by the hand aligns perfectly with the radial white and yellow lines printed onto the dial.

While the dead beat seconds hand’s step-by-step motion is the result of a traditional horological complication, the stepped seconds is also reminiscent of quartz watches. Indeed, Angelus has deliberately sought to evoke the era of quartz watches, which also have stepped seconds.

Completing the indications on the side of the case is the intuitive linear power reserve featuring a rhodium-treated hand filled with blue lacquer.

A skeleton designed for ultimate performance: 

Angelus U40 Racing Tourbillon Skeleton

As part of its return to the forefront of cutting-edge Swiss watchmaking, ANGELUS is proud to announce the launch of the latest addition to its Urban Collection. The U40 Racing Tourbillon Skeleton is powered by the A-300 in-house tourbillon movement, which was developed from the bottom up to enhance its three-dimensionality and sculptural beauty while boosting its performance and shock-resistance.

Click on the mouse wheel to see the large size ...                       BIG FOTO

When the Angelus engineers set out to develop, design and manufacture the U40 Racing Tourbillon Skeleton, they went way beyond the confines of traditional watchmaking and took their cue from cutting-edge architecture and high-performance structural engineering, some of the world’s greatest supercars and aerospace-inspired technology. The result of their labours, which involved four years of intensive R&D, is the Angelus Tourbillon Skeleton A-300 calibre.

igned to be unique

Unlike most conventional skeletonized watches, which tend to be cut-out versions of existing models, the U40 was designed to be a skeleton from the start and is based on structural optimization. As Angelus Head of Innovation Sébastien Chaulmontet explains: “When you’re designing a watch as unusual as this one, it’s vital that you’re conscious from the start of all the points you need to take into consideration. In this case, one of the main challenges was to achieve the rigidity necessary when the skeletonized mechanism is intrinsically so flimsy.”

Click on the mouse wheel to see the large size ...                       BIG FOTO

The U40’s simplicity and elegance are set off to maximum advantage by a movement that has the appeal of a three-dimensional sculpture and is a celebration of consummate mechanical achievement. Much reduced in weight, it has maximum rigidity from its beam- type bridges and the fact that all the movement’s main elements, such as the wheels and barrel, are firmly secured between two plates. This design replaces the conventional main plate and bridges construction and massively increases the mechanical resistance of the movement. The watch’s rigidity is further enhanced by the Angelus in-house six-spoke design, which reinforces the wheel train and protects the skeletonized ratchet and barrel.

With its core functions – hours, minutes and one-minute flying tourbillon – the A-300 calibre has 23 jewels, a Swiss lever escapement and measures just 4.3 millimetres in thickness and 32.8 millimetres in diameter. The 4 Hz / 28,800 vph frequency is a guarantee for high performance and precision.

Click on the mouse wheel to see the large size ...                       BIG FOTO

The ultra-slim movement has painstakingly executed contemporary haute horlogerie finishing with snailed black ADLC coating and chamfered edges. The design is enhanced by a skeletonized ratchet and barrel in the exclusive Angelus six-spoke design.

Avant-garde inside and out

The U40 Racing Tourbillon Skeleton is housed in a fabulous grade 5 titanium case that measures 42 millimetres in diameter and is only 10 millimetres thick. The design is highly complex and features a variety of curves and lines combined with alternating polished and satin-finished surfaces and a see-through back. Viewed from the side, the housing is stepped and tapers from top to bottom, the widest section accommodating the extra-large glass with the lower part narrowing to fit snugly on the wrist. The lugs are hollowed out to further increase lightness.

Click on the mouse wheel to see the large size ...                       BIG FOTO

Encompassing the dial is a multi-step bezel in black, dark grey and light grey with red imprints and a flange with an index and chapter rings. The hour and minute hands have red or white tips.

ANGELUS – U30 Tourbillon Rattrapante Skeleton

ANGELUS – URBAN U30 Tourbillon Rattrapante Titanium Limited Edition NEW

Perpetuating Angelus’ legacy of innovative chronographs:
U30 Tourbillon Rattrapante

Click on the mouse wheel to see the large size ...                       BIG FOTO

Built like a supercar, the Angelus U30 Tourbillon Rattrapante is a three dimensional and modern mechanical wrist watch that unites three coveted "haute horlogerie" complications: the tourbillon, fly-back double column wheel chronograph and split-seconds (rattrapante), while also boasting automatic winding with a power reserve display.

Click on the mouse wheel to see the large size ...                      BIG FOTO

Angelus brand proudly carries a long tradition in innovative chronograph wristwatches: this history of manufacture chronographs for the wrist began in 1925 with a monopusher. The company's first highlight was the 1942 launch of the Chronodato, the world's first serially manufactured chronograph with calendar. Throughout subsequent decades, Angelus released ever more groundbreaking chronographs, many of them including world-first complications.

Click on the mouse wheel to see the large size ...                      BIG FOTO

It took almost five years of intensive research and development secured by several patents to create the U30 Tourbillon Rattrapante. It features a one-minute tourbillon, a fly-back double column wheel chronograph, a split-seconds (rattrapante), a self-winding mechanism and a power reserve indicator. However technically complicated that combination is, it is the movement's contemporary architecture and three-dimensional design that make the Angelus Tourbillon Rattrapante truly unique. All of these complications have been reengineered based on structural optimization and skeletonized to reveal as much of the movement as possible on the dial side, all while ensuring maximum legibility of the time and chronograph functions. The skeleton bridges alone allow the display of no fewer than 15 different wheels dial side.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The movement hosts a number of complications – all fully integrated rather than modular add-ons – that are built on several layers, all visible thanks to the skeletonized bridges that create a form evoking the “A” of Angelus. To further increase the impression of depth, the movement is fully transparent around the tourbillon and treated in various shades of black and grey. A tour of the open dial begins with skeletonized central hour and minute hands.

Click on the mouse wheel to see the large size ...                      BIG FOTO

High legibility is ensured by high-contrast black movement bridges underneath light-colored hour and minute hands, as well as the fact that the latter have slightly curved profiles to catch the light from any angle. The one-minute tourbillon occupies a quarter of the dial space and can be appreciated through the skeletonized movement plate and bridges at 10 o'clock. The tourbillon is high beat with 4 Hz / 28,800 vph, a perfect fit for the watch’s character. The tourbillon cage is entirely made of non-magnetic material and reduced to the maximum to further minimize mass and optimize performance. Not only can the tourbillon itself be fully admired dial side, but also all its gearing, creating an intriguing micro-mechanical display.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The power reserve indicator, with visible gears and wheels, is positioned at 8 o'clock directly integrated onto the skeletonized bridge: a green sector indicates ideal torque while red highlights that it's time to wind the watch. The chronograph function of the U30 Tourbillon Rattrapante is among the most refined and complicated in existence: the split-seconds or “double” chronograph. This type of chronograph is highly complex to achieve, especially when combined with a tourbillon, as the energy consumption of a rattrapante mechanism is very high.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The rattrapante (or split-seconds) function allows the timing of different events that begin but do not end together, for example the times of two runners. Two separate chronograph second hands are set one over the other; the one underneath is the split-seconds hand. When the chronograph is started, both hands start moving in lockstep together, until a press of the pusher in the crown "splits" them, with the top hand continuing and the bottom split seconds hand stopping to allow an intermediate time to be noted. By again pressing the pusher, the split-seconds hand will instantly catch up to the main chronograph hand, ready again to record a new intermediate time. Integrated onto the bridge at 3 o'clock, a 30-minute counter completes the chronograph functions.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The visible column wheel for the split-seconds function is beautifully placed at 4 o'clock, positioned just below the 30-minute counter. The observer can even watch it in operation when the split-seconds function is activated. A second column wheel on the back of the movement controls the chronograph.

Click on the mouse wheel to see the large size ...                      BIG FOTO

Whereas the majority of chronographs operate in the sequence push-to-start, push-to-stop, and push-to-reset, Angelus’ U30 Tourbillon Rattrapante is first of all a "fly-back" chronograph, which means that the timing operation can be directly reset and restart without having to be stopped first. The fly-back function is very useful as it allows instant restarting of the chronograph with one push of the button instead of the three pushes necessary for standard chronographs.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The fly-back function is especially complicated to achieve when combined with the split seconds complication as the fly-back mechanism has not only one, but two, central chronograph hands to reset and restart. In addition, the forces generated on the split seconds mechanism during the instantaneous reset and restart are significant. Therefore, all of the different chronograph functions have to be painstakingly set and optimized by the master watchmaker during assembly in order to guarantee smooth operation of all functions.

  ANGELUS  History

The story of Angelus began in 1891 when brothers Albert and Gustav Stolz founded the Angelus fabrique d’horlogerie in Le Locle, Switzerland. The company quickly became renowned for developing and manufacturing pioneering movements and timepieces, both for itself and for other brands. Over the past century, Angelus earned an illustrious reputation for creating exceptional chronograph and multi-complication wristwatches, multi-display travel clocks with long power reserves, and alarm watches. Along the way, Angelus achieved a number of watchmaking world-firsts, including the first wristwatch with big date, first series wristwatch chronograph with calendar, first wristwatch with alarm and date, first automatic repeater wristwatch, and first fully waterproof repeater wristwatch.

Along with many other prestigious brands, Angelus found it difficult to compete with the arrival of quartz watches in the 1970s and the company ceased operations in the early 1980s. After lying dormant for 30 years, Angelus has now been revived by new management who have spent three years developing the next generation of visionary timepieces, the first of which is the U10 Tourbillon Lumière, which was followed up by the U20 Ultra-Skeleton Tourbillon. All models have been developed at the Angelus manufacture in La Chaux-de-Fonds, just a stone’s throw from where the Stolz brothers established their original fabrique.

ANGELUS – U20 Ultra-Skeleton Tourbillon Limited Edition

ANGELUS – URBAN U20 Ultra-Skeleton Tourbillon Carbon and Titanium Limited Edition NEW

Angelus introduces the U20 Ultra-Skeleton Tourbillon

The entire U20 Ultra-Skeleton Tourbillon watch has been conceived as a beautiful mechanical haute horlogerie sculpture. Built like a supercar, its design is streamlined and based on structural optimization. Made of sapphire, carbon and titanium, the U20 is at the forefront of cutting-edge watchmaking.

From the movement to the case design, every aspect of the U20 has been conceptualized to allow light to enter the watch and reveal the splendor of the movement’s architecture and tourbillon. The first elements one sees are the raised dome sapphire crystal of the carbon case and the mirror-polished beveled edge of the monobloc titanium lugs, all reflecting the light.

A deeper look reveals the virtually transparent movement floating in the case and allowing an unobstructed view through the watch. The quest for transparency and three- dimensionality is essential in the world of ultimate high-end watchmaking. The goal is to present the essence of the movement by removing any superfluous material. What seems to look deceptively simple to achieve requires great artistic vision and engineering prowess. The more material that is removed, the more the structure of the movement has to be carefully calculated to ensure rigidity and sturdiness.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The U20 Ultra-Skeleton even goes a step further. It does not boast an ordinary movement that has been skeletonized afterwards, but a tourbillon movement that has been created from scratch to be symmetrical, transparent and resplendent.

Click on the mouse wheel to see the large size ...                      BIG FOTO

To further enhance transparency, the U20 features a sapphire main plate. The bridges have been made of blued titanium and have been skeletonized to increase transparency even further. The bridges’ beam shape also maximizes rigidity - the latter being essential for chronometric precision.

The discerning eye will be pleased to discover that haute horlogerie has not been sacrificed on the altar of transparency: components in the Ultra-Skeleton Tourbillon have been hand- chamfered, hand-polished and hand satin-finished to ensure that they look as good as they are filigree.

Click on the mouse wheel to see the large size ...                      BIG FOTO

And to further increase visibility into the top of the three-dimensional movement, the U20 Ultra-Skeleton Tourbillon features a unique design element. The case dispenses with a bezel and instead uses a sapphire crystal dome, which also allows a sideways view onto the movement.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The U20 Ultra-Skeleton Tourbillon deserves closer inspection, which reveals many of the well- thought-out details that go into transforming a skeleton watch into an ultra-skeleton haute horlogerie watch: the variable inertia balance wheel of the tourbillon is especially designed and crafted to minimize air friction; the sapphire main plate is polished to the highest optical grade; ruby bearings are set into solid gold chatons. The ultra-light case, entirely made of carbon-fiber, titanium and sapphire, has been designed to echo the visual lightness and the technical feel of the timepiece.

The U20 Ultra-Skeleton Tourbillon is available in a limited edition of 18 pieces in carbon- fiber/titanium case.

The U20 Ultra-Skeleton Tourbillon in detail

To maximize transparency, the U20 Ultra-Skeleton Tourbillon makes extensive use of sapphire
in both the construction of the movement as well as the case. The movement is based on a
sapphire main plate, with key components supported by beautifully hand finished, blue
skeletonized satin-finished titanium bridges.

The absence of a dial and the use of a sapphire crystal dome set directly onto the carbon
fiber case allow full visual access to the movement from both the top and sides,
accentuating the three-dimensionality of the movement’s architecture.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The titanium lugs, which are securely attached to the carbon fiber case and reinforced with
an armature of carbon fiber, have a very technical shape and echo the titanium bridges of
the movement. However, the intricacy of the lugs is softened by the clever use of polished
chamfered edges and contrasting satin-finished surfaces.

Special sapphire main plate

The sapphire in the U20 Ultra-Skeleton Tourbillon is very specific, offering the essential
characteristics necessary for use in a haute horlogerie timepiece. The sapphire main plate is
first crafted from a solid block of sapphire before being painstakingly polished to be perfectly
transparent. This elaborate process results in a very precise main plate with tolerances in the
micron range. The latter is important as the sapphire used throughout the Ultra-Skeleton
Tourbillon is not decorative but 100% functional.

Movement elements

The heart of the U20 Ultra-Skeleton Tourbillon is the flying tourbillon. The tourbillon is “flying",
which means that it does not require an upper supporting bridge. This helps to maximize the
three-dimensionality of the movement and allows maximum appreciation of the technical
and aesthetical refinements throughout the movement.

The tourbillon’s steel cage is hand chamfered and polished with flat surfaces either mirror-
polished or satin-finished.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The variable inertia balance wheel is regulated by four gold weights around its perimeter. In
the quest for high performance, the rim of the balance wheel has been milled to maximize
aerodynamics and reduce air resistance.

Click on the mouse wheel to see the large size ...                      BIG FOTO

The highly engineered movement further features beam-type titanium bridges which are
skeletonized to increase transparency even more.
The titanium mainspring barrel bridge is supported by slim pillars set directly into the sapphire
main plate to optimize visual lightness.

Click on the mouse wheel to see the large size ...                      BIG FOTO

All wheels throughout the entire gear train have a specially developed six-spoke design,
again in the quest for maximum rigidity for minimum mass.

All of the rubies, which actually act as low-friction bearings, are fitted into solid gold chatons
that are embedded in the sapphire main plate. Gold chatons not only look good and attest
to the movement's haute horlogerie bona fides, they are also non-magnetic and corrosion
resistant like the sapphire itself.

After lying dormant for 30 years, Angelus has now been revived by new management who have spent three years developing the next generation of visionary timepieces, the first of which is the U10 Tourbillon Lumière, which was followed up by the U20 Ultra-Skeleton Tourbillon. All models have been developed at the Angelus manufacture in La Chaux-de-Fonds, just a stone’s throw from where the Stolz brothers established their original fabrique.
