Sea Quartz 30 GMT [42mm]
A legacy of precision now with a second time zone.
Built on the bones of the legendary Sea Quartz 30, the same model worn by Tom Selleck in Magnum P.I. the Sea Quartz GMT keeps the spirit of the original alive, with upgraded functionality for modern adventurers.

- 300M Water Resistance – Dive-ready with a screw-down crown and caseback.
- Super-LumiNova® Lume – Glows brightly through the night.
