Description

Omega Speedmaster Reduced 39mm Automatic (Ref. 3510.50)

Overview & Collector Notes

Up for sale is an exceptional collector-grade Omega Speedmaster Reduced Automatic (Reference 3510.50.00 / Case Ref. 175.0032).

This piece features an untouched matte black dial with authentic, warm creamy-custard tritium patina across the hour plots—the exact character vintage collectors look for. The baton hands are original.

The watch is fitted to a brand-new, handcrafted German Fluco perforated leather rally strap with cream contrast side-stitching that ties directly into the dial’s patina. The Fluco strap is not an Omega strap.

This watch comes complete with its original 1990s Omega presentation kit, including the original red flat presentation case with the gold “World Service” medallion, original white outer protective box, original Omega “Chronographs with fixed bezel” operating instruction booklet, and the matching worldwide service network directory. No original Omega warranty card is included. A TamboWatches serial lookup estimates 1995–1997.
