Description
Omega Speedmaster Reduced 3510.50 – Early Production | Tritium Dial | Serviced
This Omega Speedmaster Reduced 3510.50 is a rare early-production example from the late 1980s, featuring the hard-to-find warm patina tritium dial, and an early ST 175.0032 caseback without the later Seahorse engraving.
The caseback does not show an inner serial — this is consistent with early factory casebacks or genuine Omega service replacements, which were commonly unnumbered. The watch was professionally serviced in April 2025, pressure tested, and is running strong.
