Spinnaker Dumas

The Spinnaker Dumas (Ref. SP-5081) is an automatic diving timepiece inspired by watch shapes and designs of the 1970s.

This timepiece takes its name from the famed diving pioneer Frédéric Dumas.

With a more muscular and bold silhouette, the watch leans on more interesting, industrial like forms which captured the imagination of watch designers in the 1970s for practical as well for aesthetic reasons. A strong octagonal watch chassis is topped with mineral crystal 120 click uni-directional turning bezel with luminous calibrations.


Measuring the 44mm in diameter and a thickness of 16mm the watch offers 300m of Water Resistance in a relatively compact body of marine grade stainless steel. The scratch resistant sapphire crystal lens with anti-reflective coating offers durability and clarity of view.

The bezel serves to frame an unfussy, utilitarian dial featuring round and rectangular hour markers topped with Swiss Super-LumiNova for increased low light legibility. The oversized minute hands, serve the watch as a clear read out of time elapsed, delivering the watch as a unique piece of diver instrumentation.

A precise, workhorse NH35 TMI Seiko automatic self-winding movement sits inside the Dumas, offering time and date read out with its inner mechanics visible via the exhibition caseback.

Measuring 4mm in thickness the Milanese mesh bracelet on this timepiece is an enduring piece of watchmaking that nonetheless is an easy fit and wear for most of the Spinnaker range.
