The Speedmaster Reduced ST 175.0032 was a 39mm twisted-lug steel case timepiece. Omega fit the Replica Watch with what they designated to be the automatic Caliber 1140.
The last update made to the Speedmaster Reduced movement was with the calibre 3220 in 2000, again with the ETA 2892-A2 and 2020, although updates this time are said to be mostly cosmetic.
Most obvious is the vast amount of space from the central pinion to the sub dials at 9 and 3 o’clock. The dial of the Omega Speedmaster Clone Watch also reads “Automatic,” where you would otherwise have “Professional”.
Turning the watch to its crown-side, you’ll also notice that the crown and the chronograph pushers don’t line up. This asymmetry is the cause of the stacked movement construction.
The Fake Speedmaster Reduced is a variation within the Speedmaster family, as is the Moonwatch — the Speedmaster Professional — a variation within the Speedmaster family. However, a Speedmaster Reduced is not a Moonwatch Speedmaster, and a Moonwatch Speedmaster has never been a Speedmaster Reduced.
