A small GMT for a long trip
By Rafael Ortiz, Mexico City ·
Most GMTs are 40 mm or bigger. Vulcain's Skindiver GMT is 38.3 mm and 12.2 mm thick, and that's rare enough to be worth talking about.
The movement is the Soprod C125 automatic, with 42 hours and a GMT hand that you set independently. The bezel is bi-directional ceramic with a 24-hour scale. 200 m water resistance means you don't have to think about it at the pool.
The trade-off, again, is the caller GMT. If you change the local time often, you'll be pulling the crown more than you'd like. And at about $2,700 it's close to a Tudor Black Bay 58 GMT on the used market.
Still, for smaller wrists or anyone who wants a travel watch that fits under a shirt cuff, it's a lovely option.
