Your Everyday GMT Watch

GMT is one of the most sought-after complications in a mechanical watch.

It is simply... beautiful.

With just one additional watch hand, your watch can now tell time from 2 time zones. 

It is also now decorated with just the right amount of contrasting color, separating itself from all the other 3-hand watches in the market.

A complication that carries the spirit of explorers, keeps the watch design clean, and tastefully adds a color pop to a watch that is otherwise a bit mundane to some.

This classic combo of a stainless steel case with a dress dial highlights the importance of detail in watch design. The contrast polishing of the watch case and defined corners of the metal applied lume indices, all work together to subtly command respect.

It's beautiful.

  • Complete components of one 38mm Expedition series mechanical watch
