High-sea watchmaking: Arnold & Son Longitude Titanium

Arnold & Son, a benchmark in classic fine watchmaking, is exploring uncharted territory on the map of horology. Longitude Titanium is a sports-chic COSC-certified chronometer with a 42.5 mm titanium case.

The dial of Longitude Titanium is vertical satin-finished in a continuation of the bracelet’s finish, which is subtly intersected by the polished edges of its links. With a power-reserve display at 12 o’clock and an imposing seconds counter at 6 o’clock, Longitude Titanium pays tribute to John Arnold’s marine chronometers, his revolutionary vision and his decisive role in calculating longitude at sea.

The aesthetics and construction of John Arnold’s marine chronometers were necessarily classic and functional, and were adapted to the harsh conditions of the high seas. Longitude Titanium, a contemporary interpretation of the great English watchmaker’s work, coherently combines this naval heritage with a refined design and highly resistant materials.

The movement’s ‘chronometer’ certification is an essential addition to this scene, with its historical ties to Arnold’s creations and his quest for accuracy.

Ergonomic spirit

As a natural consequence of this maritime identity, Longitude presents a titanium case whose curves and profile are directly inspired by the design of contemporary sailing boats. The case middle is taut like a ship’s waterline, while the case back is basin-shaped like a keel.

The base of the bezel – the ship’s rail – is graduated with 60 notches, echoing the fluted ring of John Arnold’s marine chronometers. The finishes – polished on the flanks and satin-finished on the flat surfaces – continue this high-sea influence.

The crown, protected by a shoulder, is screwed down to guarantee water-resistance to 100 metres.

Curved spirit

With its flowing curves, Longitude Titanium is both comfortable to wear and a joy to behold. Each of the series is fitted with an integrated titanium bracelet. Everything is rounded with no straight lines, even in the finer details as the links themselves are domed.

The succession of gentle curves and combination of polished and satin-finished surfaces are a continuation of the case’s identity. Longitude Titanium is complemented by an interchangeable system and comes with an additional rubber strap.

Watchmaking spirit

The dial of Longitude Titanium has been designed in a graphic and historical spirit. This graphic aspect can be seen in the satin-finished, polished and luminescent hour-markers that recall the shape of the bracelet links.

It is also graphic in the display of its indications, which are aligned with the vertical axis of the dial: a mirror-polished power-reserve indicator shown by cut-outs in the dial at 12 o’clock, the hour and minute hands in the centre, and the imposing small seconds at 6 o’clock.

However, this layout was also chosen for its ties to John Arnold’s marine chronometers, as it was he who introduced this arrangement and established it as standard.

Chromatic spirit

Cornwall, John Arnold’s birthplace, inspired the colours of the Longitude dials.

The first edition, limited to 88 timepieces, is adorned with a sandy golden shade called ‘Kingsand’ in reference to the eponymous beach, which is one of the county’s hidden jewels. The second version sports an ocean blue, while the third and final series is a fern green.

Inventive spirit

During the 18th century, maritime trade was the main source of wealth. New routes opened up on the three major oceans, offering vast prospects. However, high-sea navigation was hampered by as yet incomplete maps and charts and, above all else, by inaccurate longitudes, i.e. the position of boats on the east/west axis. In 1714, the British Parliament passed the Longitude Act, which offered a prize of twenty thousand pounds to anyone who could develop a simple and dependable method for determining the longitude of a ship at sea. Briton John Harrison thus invented the marine chronometer, which would be used for centuries to come.

His method involved measuring the difference between the local time on the boat, by finding solar noon, and the time of an onboard precision clock capable of keeping the time at the port of departure. John Arnold developed, improved and simplified the principles presented by Harrison. He started to supply his marine chronometers in 1771, which were more robust, affordable, extremely accurate and would go on to become essential to high-sea navigation.

Kinetic spirit

At the heart of Arnold & Son Longitude Titanium beats the new A&S6302 calibre, certified by the Contrôle Officiel Suisse des Chronomètres (COSC). 

Click, to see the large size. ▶ BIG FOTO

It is wound by an oscillating weight with a design influenced by sailing. Its shape is reminiscent of the prow of an 18th-century English frigate cleaving through the water, and it is carved from a single block of 22-carat gold. Its felloe is engraved with graduations similar to those on a sextant – another maritime element.

Mechanical spirit

The calibre is lavished with the same high standard of finishes commonly seen at Arnold & Son, such as chamfered bridges with the house’s specialty ‘Rayons de la Gloire’ motif.

Like all its movements, the A&S6302 was entirely developed, produced, decorated, assembled, adjusted and cased up at the Manufacture in La Chaux-de-Fonds. This calibre features a large barrel and an oscillation frequency of 4 Hz, providing a 60-hour power reserve.

 A TRIBUTE TO BRUTALISM

  Click, to see the large size. ▶ BIG FOTO

Swiss Haute Horlogerie manufacturer Audemars Piguet is pleased to present the [RE]Master02 Selfwinding – a tribute to an asymmetrical watch created by the Manufacture in 1960 (Model 5159BA). Following in the footsteps of [RE]Master01, launched in 2020 to reinterpret a chronograph from 1943, this new limited edition of 250 pieces features an asymmetrical 41mm rectangular case in the new 18-carat sand gold alloy, whose tone oscillates between white and pink gold. [RE]Master02 is enriched by a “Bleu Nuit, Nuage 50” parted dial, divided into twelve different triangles decorated with a linear satin finish that create unique effects of light and texture when assembled.

Combining vintage aesthetic with cutting-edge performance, this new reference is equipped with the Calibre 7129, an hour and minute movement. With this new model, [RE]Master establishes itself as a collection in its own right, continuing to offer contemporary interpretations of timepieces that defined their era.

A CONTEMPORARY REINTERPRETATION

Since 1875, Audemars Piguet has followed its own path, combining watchmaking tradition with cuttingedge technology and pioneering new materials and designs. 

Click, to see the large size. ▶ BIG FOTO

Over the years, the Manufacture has used a wide variety of materials, colours and case forms, ranging from traditional geometries such as the circle, square and rectangle, to more unexpected trapezoidal or octagonal shapes. 

Click, to see the large size. ▶ BIG FOTO

This boundless creativity reflects the free spirit that Audemars Piguet has preserved and nurtured for generations. Like the remastering of music recordings, the [RE]Master collection, launched in 2020, creatively reinterprets the aesthetic codes of some of the Manufacture’s rarest timepieces, representative of their respective eras. In the 1960s, Audemars Piguet produced several models inspired by the Brutalist current, with angular geometric shapes devoid of ornamentation.

" Between 1959 and 1963, Audemars Piguet created more than 30 Asymmetrical models, most of which were produced in less than 10 pieces. [RE]Master02 is a fantastic opportunity to revive this forgotten golden age."
Sébastian Vivas
Heritage and Museum Director, Audemars Piguet

 It was also the golden age of asymmetrical watches for the Manufacture, with more than 30 models created between 1959 and 1963, most of which were produced in less than ten pieces. The 5159BA Model, launched in 1960 and produced in seven units, one of which is on display today at the Musée Atelier Audemars Piguet, belongs to this generation of watches, with its asymmetrical 27,5 mm rectangular case in 18-carat yellow gold and a dial that breaks with the codes of classic watchmaking.

Today, the [RE]Master collection expands with a new 41mm reference in sand gold, combining contemporary watchmaking with historic design.

AN ASYMMETRICAL CASE IN SAND GOLD

[RE]Master02 features a case crafted in sand gold, a new 18-carat gold alloy whose shades vary between white and pink gold depending on the light and the movement of the wrist. Launched earlier this year on a Royal Oak Selfwinding Flying Tourbillon Openworked reference, this new material, which takes its name from sand dunes, is composed of gold, copper and palladium for a warm appearance. The asymmetrical case creates a strong visual impact with its many facets. While its rectangular shape is accentuated by sharp corners and extended by integrated lugs, the case also follows the slope of the sapphire crystal at 3 o’clock.

Its surface has been entirely brushed with a satin finish for a matt, “raw” look that contrasts with the polished contours of the dial. The satin finish of the sand gold required skill and dexterity to ensure that the geometric edges and corners of the case retained their sharpness.

The caseback, also crafted in sand gold, is engraved with “Limited Edition” and harmoniously echoes the dedicated asymmetrical oscillating weight in matching tones.

A PARTED DIAL

The dial of [RE]Master02 combines different geometric forms such as the rectangle and the triangle. The “Bleu Nuit, Nuage 50” dial, obtained by Physical Vapour Deposition (PVD), is made up of twelve triangles of different sizes and shapes, separated by galvanised sand-gold-toned partitions that meet at the centre. Each individually machined brass triangle is given a linear satin finish before being placed on a brass plate using minuscule legs. Once meticulously assembled by skilled craftspeople, all the parts create a visual effect that plays with the light and brings the dial to life.

To sit in harmony with the case and the diagonal lines of the dial, the hour and minute hands are crafted in 18-carat sand gold, as is the “Audemars Piguet” signature at 3 o’clock, obtained by galvanic growth. Both the hour-makers and the date indication have been omitted to give full expression to the geometric shapes and linear satin finish. Reading the time is facilitated by the diagonals that cross the dial.

The asymmetry of the case is accentuated by the sapphire crystal, which has a 15.8° bevel for greater visual impact. Two years of research and development went into the design of this bevelled crystal to guarantee water-resistance and meet Audemars Piguet’s quality requirements.

For aesthetic coherence, [RE]Master02 is mounted on an alligator leather strap in contrasting shades of blue that match the tone of the dial. Its elegant matt finish enhances the play of light.

AN EXTRA-THIN CALIBRE

[RE]Master02 houses the Calibre 7129, an extra-thin hour and minute movement without date indication that is based on the Calibre 7121, launched in 2022 on Royal Oak “Jumbo” Extra-Thin models.

This 2.8mm thick movement produces more energy thanks to its new construction and its larger barrel, enabling the mechanism to achieve greater precision over a longer period of time.

*Melding geometrical figures, the dial is composed of 12 triangles of
different shapes and sizes separated by galvanised sand gold partitions

The oscillating weight, mounted on ball bearings, is equipped with two reversers to ensure bidirectional winding. In addition, inertia blocks have been inserted into the thickness of the balance wheel to prevent aerodynamic friction from slowing it down.

In keeping with the Haute Horlogerie tradition, the Calibre 7129 features refined decorations such as Côtes de Genève, circular satin, snailing, sunray brushing, circular graining and polished angles, all of which can be admired through the sapphire caseback.

The latter also reveals the dedicated 22-carat gold oscillating weight, whose sand gold tone subtly echoes the colour of the case.

A COLLECTION IN ITS OWN RIGHT

Launched in 2020 to celebrate the opening of the new Musée Atelier Audemars Piguet in Le Brassus, the first model in the collection has a vintage aesthetic. Reinterpreting a rare chronograph from 1943, this limited edition of 500 pieces retains the aesthetic codes of the original timepiece with its two-tone steel and pink gold case enriched with a gold-toned dial.

 However, this remastered edition has a modern twist with a larger, 40mm case, repositioned counters enhancing legibility and, of course, a latest-generation chronograph movement, the Calibre 4409, whose refined finish is visible through the sapphire caseback. Combining the design of the 1940s with the latest watchmaking technologies, [RE]Master01 symbolises both the tradition and the pioneering spirit that pervades every Audemars Piguet watch.

 Today, the [RE]Master collection expands with this limited edition, which allows Audemars Piguet to reinterpret some of its older timepieces, which have left their mark thanks to their aesthetic singularity,

Click, to see the large size. ▶ BIG FOTO

[RE]Master02  is enriched by a “Bleu Nuit, Nuage 50” dial that combines different geometries. It is subdivided into twelve individually machined brass triangles that have been decorated with a linear satin finish before being placed on a brass plate with minuscule feet. The triangles are separated by sand gold partitions that facilitate the reading of the time.

 “Seek Beyond.”
