Swiss Haute Horlogerie manufacturer Audemars Piguet unveiled a new animation of its Royal Oak Concept Flying Tourbillon GMT in 44 mm. For the first time, the complicated timepiece’s titanium case is topped off with a green ceramic bezel for a highly contemporary look. The black architectural movement, visible through the dial and sapphire case back, features green CVD-coloured inserts matching with the bezel’s hue – a powerful contrast furthering the watch’s high-tech aesthetic.
The new Royal Oak Concept Flying Tourbillon GMT model encompasses a sandblasted titanium case enriched with a bezel, crown and push-piece, all crafted in green ceramic and finished by hand with an alternation of satin-brushing and polished chamfers. Although green ceramic was first introduced at Audemars Piguet in the Royal Oak Offshore collection in 2018, this material makes its first appearance this year on the Royal Oak Concept.
Zirconium Oxide (ZrO2) powder, modified to obtain a green pigmentation once baked, is mixed with dedicated binder content before being transformed into ceramic through a complex industrial flow requiring different stages of high-precision machining. The exact composition of ceramic remains the secret of its manufacturers. The components achieve their final green colour only once they have been sintered at more than 1,400°C. Reaching a homogeneous colour represents an additional challenge as ceramic’s final colour depends on the sintering temperature, which allows no variation. The Le Brassus artisans have then finished each ceramic component with the same detailed and meticulous hand-finished as they would if they were honed from precious metals, endowing the timepiece with a rich play of light.
As per Royal Oak Concept design codes, the architectural movement ticking within takes centre stage on both the dial and caseback sides. To further enhance the introduction of green ceramic, the hand-wound Calibre 2954 has evolved to contrast the movement’s black PVD bridges with evocative green CVD-coloured inserts. A very thin layer of green colouring, specifically developed for the occasion, has been applied by Chemical Vapour Deposition (CVD). A precursor gas is injected into a chamber, which is then heated until the gas breaks down and bonds to the surface of the different elements. In addition to offering a rich play of light, this technique ensures colour homogeneity across the components, as well as unalterable colouration over time.
The timepiece’s contrasting tones are illuminated by pink gold accents. The pink gold hands filled with luminescent coating and the applied AP monogram at 12 o’clock are echoed by the pink-gold-toned flying tourbillon cage and escapement components peeking through the openworked bridges. The transferred white hour-markers on the black inner bezel add yet another bright touch.
A green rubber strap, fitted with a sandblasted titanium AP folding clasp, completes the watch’s avant-garde design. The timepiece also comes with an additional black rubber strap.
The hand-wound Calibre 2954 combines the prestige of the flying tourbillon with state-of-the-art displays: a second time zone indication – also known as GMT (Greenwich Mean Time) – and a crown position indicator at 6 o’clock with the letters H, N and R respectively standing for the time-setting, neutral and winding positions of the winding stem.
The GMT display located at 3 o’clock provides an instant reading of the time in a second time zone. It is adjusted using the push-piece at 4 o’clock (one press adjusts the time by one hour). The indication of the second time zone, based on 12 hours, comprises two superimposed discs. The hour disc, which completes a rotation in 12 hours, is crafted in sapphire and encompasses white figures outlined in black. In contrast, the day/night disc, honed from brass, completes a turn in 24 hours and has two coloured areas: a white half for daytime and a green CVD-coloured half representing night time.
