The synonym for replica Omega Speedmaster Reduced is Speedmaster Automatic. Omega sold the reference 3510.50 under that name, so replica listings reuse it as Speedmaster Automatic, Speedy Reduced, 39 mm Speedmaster, or 3510.50 clone. All of those labels point to the same smaller, self-winding chronograph, not the 42 mm hand-wound Moonwatch.
Why the Names Overlap
Omega made the Reduced from 1988 to 2009 as a lower-cost automatic alternative to the Moonwatch. The case is 39 mm wide and about 12 mm thick. Inside sits an ETA 2892 base with a Dubois-Depraz chronograph module, which is why the subdials sit closer to the center than they do on a Moonwatch. Replica makers copy the outside, and sellers describe it with whichever name gets searches.
Omega Speedmaster Reduced: A Practical Buying Guide
Synonyms You Will See in Listings
- Speedmaster Automatic
- Speedy Reduced, or just Reduced
- 39 mm Speedmaster
- 3510.50 clone or 3510.50 replica
- Auto Speedy
- Triple-date Speedy, when a seller confuses it with the day-date model
Check a Listing in Six Steps
- Confirm the case width is 39 mm. A 42 mm listing is a Moonwatch case with the wrong name.
- Ask for the reference the seller claims. The base steel model is 3510.50.
- Ask whether the movement is automatic. The Reduced is self-winding; the Moonwatch is hand-wound.
- Look at subdial spacing. Subdials close to the center axis match the module layout.
- Request a clear photo of the dial text and the caseback engraving.
- Compare the pusher shape and crown position against press photos of the 3510.50.
Specs That Matter More Than the Name
A replica with the right label can still be wrong. Check the 19 mm lug width, the domed crystal profile, and the tachymeter print. The bezel should be steel with a black insert, and the dial should carry applied markers rather than painted ones. Replica movements range from basic quartz to decorated automatics, so ask what is inside before you pay.
Naming Traps
Reduced does not mean a shrunken Moonwatch. It means a different movement architecture, so a seller who calls a 42 mm watch a Reduced is mislabeling it. Replica watches also carry no Omega warranty or service support, and they are not collectible. Use the name to identify the model, then judge the watch on its own specs.
