A. Lange & Sohne – 1815 Rattrapante Perpetual Calendar Handwerkskunst White Gold Edition

Blue brilliance as a tribute to artistic craftsmanship

With an exclusive HANDWERKSKUNST edition, A. Lange & Söhne demonstrates how artisanal virtuosity becomes truly grand art. The dial and the hinged cuvette of the new 1815 RATTRAPANTE PERPETUAL CALENDAR HANDWERKSKUNST consist of blue enamelled white gold with elaborate relief engravings.

In its launch year, the 1815 RATTRAPANTE PERPETUAL CALENDAR attracted considerable attention in two respects: in January 2013 at the Geneva Salon, it was enthusiastically received by the horological community as a technically and aesthetically convincing union of classic complications that rank among the most sophisticated mechanical ensembles in precision watchmaking. At the Grand Prix d'Horlogerie de Genève in that same year, the watch was not only the winner in the Grand Complications category but also won the Public's Choice Award.

This remarkable timekeeping instrument was the ideal starting point for a limited 20-watch HANDWERKSKUNST edition. It is the sixth A. Lange & Söhne model with this attribute that stands for the particularly artistic decoration of the movement, dial and case.

The 1815 RATTRAPANTE PERPETUAL CALENDAR HANDWERKSKUNST confronted the finishers, engravers and enamel artists with an exciting challenge: to raise the decorative opulence for which the manufactory is known to the next level with rare and in some cases revived techniques as well as innovative ideas.

This is the first model to combine enamel art and engraving on its dial. Solid white gold is the substrate for the deep-blue enamel beneath which the sculpted contours of the relief-engraved stars appear to be a visual extension of the moon-phase display.

The Arabic numerals are flush with the enamel and harmonise perfectly with the rhodiumed white-gold hands of the time and calendar indications as well as of the power-reserve indicator.

The colour of the enamel is echoed by the lunar disc as well as the blued-steel minute-counter hand. These elements contrast exquisitely with the four recessed subsidiary dials in argenté-coloured white gold. The chronograph hand offers an especially distinctive colour accent: it is crafted from gold-plated steel. The dial is framed by an argenté-coloured flange ring with a traditional railway-track minute scale.

The moon theme recurs on the hinged cuvette that protects the sapphire-crystal caseback. It depicts the goddess Luna, the ancient mythological personification of the moon, executed in relief and tremblage engraving.

The medallion shows her with her characteristic attributes: a billowing veil, a crescent moon diadem and a torch with which she lights up the darkness. The medallion is surrounded by a raised star and cloud relief in blue enamel.

Artistic movement decorations reflect the technically ambitious multiple-complication timepiece. The German-silver train bridge is finished with a granular texture often found in the movements of historic pocket watches.

Relief and tremblage engravings on the operating-lever, cover and chronograph bridges as well as on the rattrapante and balance cocks reflect the stellar motif of the dial. In all other respects, the finissage of the 631-part manufacture calibre L101.1 complies with the strictest Lange standards.

The split-seconds chronograph allows the measurement of lap times and consecutive times. It is controlled by two column wheels – one for the chronograph and one for the readily visible rattrapante mechanism which is activated by a pusher at 10 o'clock. The perpetual calendar mechanism correctly displays the individual durations of each month in the course of a calendar year, including all leap years until 2100.

Integrated in the subsidiary seconds dial at 6 o'clock, the moon-phase display is calibrated to remain accurate for 122.6 years. The manually wound movement has a maximum power reserve of 42 hours. A power-reserve indicator reminds the owner when it is time to rewind the watch.

The 1815 RATTRAPANTE PERPETUAL CALENDAR HANDWERKSKUNST comes in a 41.9 millimetre white-gold case with an edition engraving. It is worn on a blue-grey alligator leather strap secured with a white-gold deployant buckle.

Bell & Ross – Vintage BELLYTANKER

Bell & Ross – Vintage BELLYTANKER Automatic

Vintage BELLYTANKER

Speed has always been a key source of inspiration for Bell & Ross. Since it was founded, the watch brand has also demonstrated a passion for the very latest technology.

Click, to see the large size. ▶ BIG FOTO

These factors constantly push the brand to excel, and to develop highly complex mechanisms for its watches. By extension, Bell & Ross is interested in all extreme machines.

B-ROCKET

In 2014, Bell & Ross developed the B-Rocket, a retro-futuristic concept motorcycle, streamlined like a jet plane.

This two-wheeled wonder pays tribute to the very finest experimental aircrafts produced by the US aviation industry in the fifties and sixties.

AÉRO-GT

In 2016, the brand took the same approach with the Aero GT.

The watchmaker created an avant-garde aircraft-inspired supercar, with astonishing performances.

BELLYTANKER

This year, Bell & Ross has returned to its passion for engineering, creating its retro-influenced Bellytanker racecar, with missile-like aerodynamics. It is built using a fuel tank from a fighter plane. Fitted with an engine and four wheels, this tank is transformed into a streamlined racer.
.

The Bellytanker is best known for taking part in speed trials on the huge salt lake flats of the North American West.

Click, to see the large size. ▶ BIG FOTO

These gigantic open stretches of desert, where most of the water has evaporated, are particularly well suited to motor racing competitions. The Bonneville Salt Flats in Utah are the most famous example.

A BRIEF HISTORY

Originating in the forties and fifties, the term «Bellytank» initially referred to the emergency drop tank fitted in the belly of fighter planes. «Bellytanker» is now mainly used for the high-speed race cars manufactured directly from these spare tanks.

Their history dates back to the end of the war. Bill Burke, an American speed freak, wanted to build an ultra-fast car to take part in the races being held on the salt flats. He had fought in the South Pacific, and had grown to love the elegance of these fighter plane drop tanks, with their aerodynamic lines as if sculpted by the wind.

To his eyes, they looked like the perfect foundations on which to build his speed machine. He was not wrong: their droplet shape ensured exceptional performance. At the end of the war many military components were sold off cheap. In 1946, he bought a drop tank from a North American P-51 Mustang for $35. He used it to build a bright yellow mini hot-rod. He fitted the tank that formed the bodywork, on a chassis, powering it with a powerful V8 engine. He took his prototype to the Bonneville salt lake races to test it.

Without realizing it, he had created the world’s first Bellytanker. The shape and design of this aerodynamic vehicle have ensured its place in the great aeronautical history of North America in the forties and fifties. It is also enshrined in the annals of motor racing with the Hot Rod and the Streamliner. In the automotive world, it also rapidly acquired iconic status.

A NEW RACER AT BELL & ROSS

Bill Burke went on to develop vehicles based on tanks from a lighter plane, the Lockheed P-38 fighter. Bell & Ross has designed its own vehicle, taking these later versions of the Bellytanker as its inspiration.

Being part of a plane on wheels, this new vehicle is perfectly aligned with the spirit of the watch brand, which has aviation and the military in its DNA. This retro-futuristic racer is the latest in a line of extreme machines developed by the firm. It combines both aeronautical influences and numerous nods to the watchmaking world.

So, the metal of its bodywork is like the case of a watch. The glass covering its cockpit echoes an ultra-curved crystal. The copper-cultured trim evokes the dials of timepieces from this era.

Its tail fin, designed to stabilize the vehicle, is a reference to the aviation codes, as is the matte black of its “nose”. This color is used on certain stealth fighters to avoid reflections.

BR V1-92

Movement
Self-winding with three hands; it displays the hours, minutes and seconds. The date is at 4.30. This classic version is designed for the purist.

Case
The small 38.5 mm case in brushed steel harks back to the watches of the forties and fifties, with a nod to the cockpit of the P-51 Mustang. Flat and thin, it imbues the watch with elegance. The solid case back features an engraved profile of the Bellytanker. Lastly, the ultra-curved sapphire crystal, with its vintage overtones, recalls the round windows in classic plane cockpits.

Dial
The color scheme matches the Bell & Ross racer. The metallic copper of the dial echoes the color of its wheel rims. The black seen on the details of the minute track recalls the car’s nose. Finally, the steel used for the case, numerals, indices and hands pays tribute to its sculpted bodywork. The metal indices and numerals are appliques. The metal skeleton hands are filled with Superluminova, so that they remain visible at night. The aircraft-shaped counterweight on the seconds’ hand is one of the new Bell & Ross stylistic signatures.

Strap
Exceedingly soft and supple, this dark brown leather strap is aged for a vintage look.

BR V2-94

Movement
The chronograph, invented to measure short periods of time, is a key motor racing function. This variant houses a chronograph with two counters: a 30-minute counter at 9 o’clock and a central 60-second counter. The date sits between 4 and 5 o’clock.

Click, to see the large size. ▶ BIG FOTO

Case
The satin-finished polished steel of this larger 41 mm case hints at the P-51 Mustang’s tanks. The sapphire case-back allows glimpses of the chronograph mechanism’s gear train. The version with a solid case back features an engraved profile of the B&R Bellytanker. The crown and push buttons are screw-down for improved water-resistance. The fixed bezel features a tachymeter scale, enabling the speed of a racecar to be calculated at any time.

Dial
This style is known as a «Panda» dial, so-called because of the contrast between the black counters and gold dial. The color scheme used matches that of the Bellytanker. The metallic copper of the dial echoes the color of the racer’s wheel rims. The black of the detailed line on the minute track is also found on the car’s nose. Finally, the steel used for the case, numerals, indices and hands is a nod to the vehicle’s sculpted bodywork. The metal indices and numerals are appliques. The metal skeleton hands are filled with Superluminova, so that they remain visible at night. The aircraft-shaped counterweight on the second’s hand is one of the new Bell & Ross stylistic signatures.

Strap
There are two options:

• Retro-inspired dark brown leather, which is exceedingly soft and supple.
• A very sporty metal bracelet, ensuring this chronograph is a pleasure to wear.

Bell & Ross loves to take its passion for extreme machines to the limits. Its new Bellytanker car naturally continues the line of vehicles that precede it: the B-Rocket motorbike and the Aero GT supercar.

Comprised of two timepieces, the new Bellytanker collection adopts the round case of the Vintage model, whilst remaining resolutely modern. It is designed to evoke the legendary era of record-breaking races in the North America of the fifties.

Participants sped across the salt lakes, most notably at Bonneville, in their super-fast homemade hot rods. This collection is aimed at contemporary and enthusiastic drivers, with a love for vintage.
