Travelers who love dive watches usually have to choose between a GMT and a diver. The Tissot Seastar 1000 Quartz GMT removes that choice: a 40mm steel dive watch rated to 300 meters, with an independent fourth hand that tracks a second time zone on a 24-hour scale.

The black and green bezel ring is the giveaway, a subtle twist on the classic two-tone GMT look that makes this Seastar instantly recognizable. Set the GMT hand to home time and you can read both your local hour and the time back home at a glance, which is just as handy on calls with colleagues abroad as it is on long-haul trips. Swiss quartz keeps both time zones accurate, with an end-of-life indicator to flag a low battery.

At 40mm and 11.77mm, the case is compact for a GMT diver. Screw-down crown and caseback keep it watertight, the dial and hands carry Super-LumiNova, and the quick-release steel bracelet with push-button folding clasp feels secure on the move.
