Omega Speedmaster Reduced 3510.50

Omega Speedmaster Reduced 3510.50

The Omega Speedmaster needs no introduction – it is the most famous watch in the world, the first timepiece on the moon. The reference 3510.50 offered here, better known as the “Speedmaster Reduced,” brings this legendary DNA into a more compact, everyday-friendly format. With its automatic caliber 3220 – a chronograph movement based on the proven ETA 2890-A2 with an added Dubois-Dépraz module – it offers the convenience of self-winding, while the design unmistakably remains Speedmaster: the black dial with Tri-Compax layout, the tachymeter bezel, the Hesalite dome, and the typical case profile with asymmetrical lugs. The hour indices on this example have developed a warm, creamy patina, giving the watch a pleasantly matured appearance and distinguishing it from newer models.

This piece was freshly serviced at the end of February 2026 and is in well-maintained, good condition. The case shows the usual signs of wear from regular use of a chronograph – fine scratches on the polished surfaces and light wear on the case back with the engraved Speedmaster seahorse. The original Omega bracelet with the Speedmaster-signed folding clasp shows normal wear; the clasp mechanism is slightly loosened and should be adjusted when possible. The tachymeter bezel is in good condition without major damage. Thanks to the recent service, this Speedmaster can be worn on the wrist without concern.
