In order to grasp the essence of the Royal Oak Offshore Selfwinding Tourbillon Chronograph, you need to pick up the watch with your eyes closed and only open them after turning it over. Housed within a case that strongly hints at its innate sturdiness, protected by a sapphire crystal and a solid back secured by eight polished steel screws, a true masterpiece is revealed: the new selfwinding Calibre 2897, equipped with a tourbillon and a chronograph. A set of 335 parts on which the manually adjusted, corrected, bevelled and decorated surfaces create a shimmering play on light and shade. The automatic winding is ensured by a peripheral oscillating weight, while its chronograph is equipped with a column wheel and its tourbillon optimises its rating precision. The Royal Oak Offshore Selfwinding Tourbillon Chronograph is in harmony with the finest watchmaking traditions, and yet turning it over reveals an eminently contemporary spirit. It displays a sophisticated and powerful design, that of the legendary Royal Oak Offshore collection, supported by a combination of black-coloured materials: forged carbon for the case middle, ceramic for the bezel and rubber for the strap. A watch with two faces, an encounter between contrasts or a watchmaking union of opposites, the Royal Oak Offshore Selfwinding Tourbillon Chronograph is an amazing blend of two worlds.
