Understated Power

Rolex GMT-Master II

The GMT-Master II was designed for those who operate across time zones — a tool watch evolved into a symbol of global presence. This configuration features the refined black and grey Cerachrom bezel, often referred to as “Bruce Wayne” for its discreet and strategic character.

Housed in a 40mm Oystersteel case, this timepiece is powered by Rolex’s Calibre 3285, delivering a 70-hour power reserve with dual time zone functionality. Paired with the elegant Jubilee bracelet, it elevates comfort while maintaining a strong, understated presence.

Not loud. Not obvious.
But instantly recognized by those who understand.
