Dumas GMT Automatic
Ref.: SP-5119-22
The Spinnaker Dumas GMT Automatic is pure vintage-cool wrapped in ocean vibes. Featuring a deep blue dial (and more colors available) inside a sturdy 44mm stainless steel case, it brings retro dive-watch style into today. The automatic GMT movement and GMT bezel makes tracking two extra time zones easy, while bright lume keeps things readable long after dark. Whether you’re island hopping or hitting your local hangout, this watch is relaxed, reliable, and ready to roll.
