Spinnaker Dumas GMT Automatic

Spinnaker expands its best-selling Dumas collection of dive watches by introducing an Automatic GMT model.

Inspired by famed dive pioneer Frederic Dumas, this diving watch collection fuses 70s inspired style with nautical inspired design and contemporary watchmaking.

With a series of bi-colour bezels, the range features pop, flair and character even as the dial is a study of balance, legibility and functionality. These features are highlighted with an assembly of suitably weighted hour and minute “plongeur” style hands and round and baton like indexes that are generously lumed with Swiss Super-LumiNova for maximum impact visibility in low light conditions.

Water-resistant to 300m, this diving watch comes with a solid stainless steel case measuring 44mm in diameter and 15mm in thickness.

The octagonal case is carefully chamfered and is bold and striking while still being a comfortable fit. A scratch resistant sapphire crystal lens adds maximum legibility, visibility and clarity.

The Spinnaker Dumas GMT watch houses the Seiko TMI NH34 GMT Japanese Automatic movement. The independent GMT dual time hand reads off a secondary time zone with the external uni-directional 24-hour bezel allowing for a third time zone read out a glance.
