The original GMT watches emerged during the 1950s, part of a jet-setting era that opened a whole new world of exotic destinations. The GMT 3 Timezone COSC is born of the spirit of that time, with a retro-temporary design reminiscent of vintage aviation watches. Distinctive looks and vivid yellow detailing are all enhancements to a classic.

The TRI-02’s case is crafted from stainless steel in Switzerland, its sleek shape a striking example of the nation’s engineering capabilities. Yet it’s what you’ll see through its exhibition caseback that makes this watch possible. A Sellita SW330 movement powers a fourth GMT hand, read against an inner 24-hour ring so its user can track a second timezone; an outer 24-hour bezel can be adjusted by the TRI-02’s upper crown to set and follow a third.

Each SW330 movement found inside the TRI-02 has also has also passed through the Contrôle Officiel Suisse des Chronomètres, having been tested in a variety of positions and temperatures to guarantee optimum performance throughout. The result: guaranteed accuracy within -4/+6 seconds per day, placing the TRI-02 in the top 6% for all Swiss-made watches.
