The combination of a tourbillon’s precision with the practicality of the GMT function makes the Ocean Tourbillon GMT both extremely useful, while offering the wearer a timepiece that encapsulates two of high horology’s most significant achievements on the wrist, with a contemporary design that makes it uniquely Harry Winston.

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 masterful composition of precisely arranged elements. This multi-level composition places the tourbillon, as it deserves, 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.

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, this timepiece offers a power-reserve of 110 hours.

Both an homage to one of fine watchmaking's most sophisticated and intriguing innovations, and a demonstration of the mastery of inspired design that is the hallmark of watchmaking at Harry Winston, the Ocean Tourbillon GMT is available in a strictly limited edition of 100 pieces worldwide: 50 pieces in 18K white gold and 50 pieces in 18K rose gold.
