All these innovative complications are incorporated into the same, curved tonneau-shaped case, rendered in 4N (18K) pink gold. It is paved with 432 TW/VS diamonds, which total weight constitutes 8.92 carats.
The case is fitted with push-pieces, which were intentionally created to enhance the aesthetic appeal of the watch and ensure ultimate comfort. Manufacturing the final prototype of the case’s double curvature required over 90 operations and 16 months of painstaking effort.
The Gran'Chrono Astro watch case embraces a breathtaking dial, embellished with a black guilloche pattern. The dial reveals the day and month exhibition window, located at 12 o’clock. The moon phase aperture is placed at 6 o’clock. The dial also exposes a 12-hour counter, nestled at 6 o’clock and 30-minute counter at 12 o’clock.
Animating the functions of hours, minutes, day, date, months, moon phase and chronograph is an automatic calibre, entirely executed by the Dubey & Schaldenbrand brand.
Featuring hand-decorated gold finishing, the movement incorporates a chronometer-quality escapement, a skeletonized rotor, as well as a stop seconds system to provide absolutely accurate time-setting.
The Dubey & Schaldenbrand Gran'Chrono Astro watch is accompanied by a Louisiana alligator leather strap.
