This particular tourbillon (a technical term stemming from French word that may be alternatively translated as whirlwind, whirlpool or simply swirl) floats in an ocean of innovation. Such is at any rate the visual effect sought by Harry Winston which releases the stellar complication from its traditional construction. Rather than a tourbillon mounted on the movement mainplate, the Ocean Tourbillon Big Date presents the carriage and the regulating organ in such a way that no visible mechanical attachment obstructs the view. The result is a surprising aesthetic accentuated by the asymmetrical display of the functions according to the iconic codes of the New York-based House. The date appears on the right, and the hours and minutes on the left, forming a perfectly readable overall effect powered by a mechanical hand-wound  movement with a 110-hour power reserve.
