Omega mariner 396.0840

1980 Omega Seamaster Mariner Quartz “2-Tone” – Ref. 396.0840

An unmistakably sharp piece of late-1970s and early-1980s Omega design. The Seamaster Mariner combines angular integrated-bracelet styling with the technical ambition of Omega’s early quartz era, resulting in a watch that feels every bit as bold and futuristic today as it did upon release.

This reference 396.0840 features the desirable two-tone construction with gold-tone bezel accents against the brushed steel case and bracelet. The clean black dial with applied markers and framed day-date display gives the watch a distinctly architectural appearance, while the integrated bracelet completes the unmistakably period-correct luxury sports watch aesthetic.

With its faceted case design, slim profile, and crisp finishing throughout, the Mariner sits perfectly within the design language that defined high-end sports watches of the era.

Technical background

The Seamaster Mariner formed part of Omega’s push into advanced quartz technology during the late 1970s and early 1980s. Powered by an in-house Omega quartz caliber, these watches combined precision electronic timekeeping with integrated case and bracelet designs inspired by the emerging luxury sports watch trend of the period. Compared to many contemporary quartz watches, the Mariner stood out through its high-quality finishing and distinctly upscale construction.
