Pre-Owned OMEGA Seamaster 120m 166.088 watch

Pre-Owned Vintage OMEGA Seamaster 120 Ref. 166.088 "Spider Dial"

The Omega Seamaster 120 Ref. 166.088 is a vintage diver's watch that stands out for its distinctive presence, robust engineering, and growing rarity in the collector world. Introduced in the early 1970s, this reference marked a significant point in Omega’s dive watch evolution — designed to offer professional-grade performance in a larger, bolder format that appealed to the emerging sports watch market of its era.

This particular example features the rare "Spider Dial" — a naturally aged cracked lacquer effect that has developed over time, transforming what was once a uniform black dial into something totally unique. Collectors now celebrate these dials for their character and individuality, especially when the cracking is symmetrical and evenly distributed, as it often is on well-preserved examples like this one.

Why the Seamaster 120 Ref. 166.088 Matters

• Oversized Vintage Case: At 40mm, this Seamaster was considered oversized for its time — a precursor to modern diver sizing, making it incredibly wearable today. The monobloc-style case (solid caseback) improves water resistance and adds to its tool-watch charm.

• Historical Calibre 1002: Powered by the Omega Calibre 1002, a high-beat, 28,800 vph automatic movement developed during Omega’s push to compete with Rolex and Zenith in the precision watch market of the 70s. This movement features a quickset date function and is known for its reliability and smooth sweep.

• “Spider Dial” Patina: This aging effect was not intentional but has become highly desirable. Each spider dial is different, making every example unique. It reflects both the passage of time and the watch’s journey through decades — a patina that can’t be replicated.

• Under-the-Radar Cult Status: While not as universally known as the Seamaster 300 or the Speedmaster, the 166.088 has developed a cult following. With clean vintage examples becoming harder to find — especially with original bracelets and boxes — these watches are quietly rising in value and collectibility.
