Audemars Piguet Royal Oak Concept Tourbillon GMT Replica Watch is an almost totally scratchproof composite material that can be scratched only by diamonds, calling for the use of special milling-cutter machines equipped with diamond-tipped tools. Treating the roughed-out surfaces and edges to a polished or satin-brushed finish represents a daunting technical challenge, due to ceramic’s inherent resistance to abrasion. It takes around 8 hours to make the Royal Oak Concept GMT Tourbillon’s bezel, compared with 45 minutes if it were steel, calling upon all the savoir-faire of the watchmakers and engineers. As well as giving an exceptionally smooth final appearance, ceramic has a practical purpose, displaying extreme resistance to wear.
Its sculpted titanium case Audemars Piguet Royal Oak Concept Replica Watch and integrated rubber strap combine with a white ceramic bezel to frame the highly architectural array of tourbillon carriage and second ‘GMT’ time-zone display inside – case and movement in perfect harmony. New for 2014, however, is the flash of pure white centre-stage: an intricately machined upper bridge made of white ceramic – only possible now, thanks to Audemars Piguet’s ongoing advances in materials science.
The Audemars Piguet Royal Oak Replica Watch ultra-hard Alacrite 602 case was more rounded to highlight Genta’s signature octagonal bezel and its eight hexagonal screws. The dial was left off, exposing the advanced micro-mechanics ticking within. All these revolutionary design codes have persisted throughout the Concept series, from 2008’s Royal Oak Carbon Concept Tourbillon and Chronograph – an ultra-light timepiece that was the first to combine a forged-carbon case and movement mainplate – to the Royal Oak Concept GMT Tourbillon of 2011, with ultra-light, ultra-resistant titanium case and black-ceramic octagonal bezel, pushpieces and crown.
The Audemars Piguet Replica Watch display provides an instant reading of the time in a second time-zone. It is adjusted using the pushpiece 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, making it easy to tell the time. The first, on which the figures are inscribed, completes one turn in 12 hours. The second, just below, completes a turn in 24 hours and has 2 coloured areas: a white half for daytime and a black half for night-time. This makes it easier to read the figures.
