Reasons to Bid

This Omega Speedmaster Ref. ST105.003-65 is one of the last straight-lug ‘Pre-Moon’ Speedmasters, representing the design used by NASA astronauts during the early Gemini program. The watch retains its original dial, which shows an even and natural patina, giving it a clear period character without signs of heavy restoration. The case remains in good, well-preserved condition with lugs that appear consistent with long-term careful use. As a reference produced only for a limited time in the mid-1960s, the 105.003 is less common than later Speedmaster models and is closely linked to the early history of space exploration. For collectors seeking an authentic Pre-Moon example with original components and the fan-favorite Cal. 321 as well as stable overall condition, this piece presents a perfect opportunity.
