Omega Seamaster (Pre-owned - Good) — USD 1,229 on eBay

The Omega Seamaster 120, introduced in 1967, represents Omega's early foray into professional dive watches, positioned as a more accessible alternative to the Seamaster 300. It offered robust water resistance in a more compact and versatile case design, appealing to both enthusiasts and those seeking a capable sports watch for everyday wear and light diving activities. This reference helped solidify Omega's reputation in the burgeoning dive watch market of the era. This particular Seamaster 120 features a stainless steel case, often with a diameter around 37mm, and is typically powered by an automatic mechanical movement, such as the Omega Caliber 552 or 565, known for their reliability. The watch is characterized by its rotating bezel, often bi-directional, and a screw-down case back, contributing to its water resistance. Dials varied, but commonly featured luminous hour markers and hands for legibility in low light conditions. For collectors, the Seamaster 120 holds significance as a transitional model, bridging the gap between earlier Seamaster models and the more specialized dive watches that would follow. Its enduring design and robust construction mean that well-maintained examples can still perform to their original specifications, as demonstrated by successful pressure testing. It offers a tangible connection to Omega's heritage in aquatic timekeeping.
