The Ocean Tourbillon GMT combines a tourbillon, one of fine watchmaking’s most sophisticated and technically challenging complications, with a dual time-zone function.
The dial has been redesigned with in a dynamic new all-black interpretation, in which the dual time zone displays and the tourbillon are arranged in overlapping circles, leading the eye around the dial in a composition of precisely arranged elements. This multi-level composition places the tourbillon in the foreground, where its hypnotic rotation draws the viewer in; mounted on the central axis of the tourbillon is a seconds hand rotating, as the tourbillon does, once per minute.
The time zone to which the local time display is set is shown by a pointer indicating a reference city, revealed in an aperture at the top of the dial. A day/night indication for the second time zone completes the wealth of information presented legibly.
The timepiece is equipped with a self-winding mechanical movement comprised of 550 parts finished to the highest standards of haute horlogerie, hand chamfered with vertical Côtes de Genève and black ruthenium treatment. It offers a power-reserve of 110 hours.
