Story & Heritage

The Mariner I wears its quartz identity proudly. Omega placed a small “Quartz” plaque directly beneath the dial, where it becomes part of the case design. The angular steel body flows into broad, tapering bracelet links, giving the watch a continuous profile on the wrist. Against all those straight lines, the round black dial and flowing Seamaster script soften the design.

Turn it over and the familiar Seamaster seahorse sits at the centre of the case back. That detail links the Mariner’s more industrial styling to the wider Seamaster family. For a collector drawn to vintage Swiss quartz, the appeal is in that pairing: an unmistakably Omega dial and a case that looks quite unlike a conventional round Seamaster.
