The Omega Speedmaster Reduced ref. 3510.50 measures 38.5 mm across the case, so listings that say 38 mm are rounding down. Replicas of this reference vary in case thickness, subdial function and dial print. Check those three points before you buy.
Replica Speedmaster Reduced 38mm Price: Tier-by-Tier Buying Guide
Original specs to compare against
- Case: steel, 38.5 mm diameter, about 12 mm thick, 18 mm lug width.
- Crystal: hesalite (acrylic), domed. Not sapphire on the standard 3510.50.
- Bezel: black aluminum tachymeter insert, 500-unit scale.
- Movement: Omega cal. 3220, automatic, built on an ETA 2890-A2 base with a Dubois-Depraz chronograph module.
- Subdials: small seconds at 9, 30-minute counter at 3, 12-hour counter at 6. No date on the standard reference.
- Caseback: solid, screw-in, with the seahorse medallion.
- Water resistance: 30 m rating on the original.
Published numbers differ. Case thickness appears as 11 mm to 12.5 mm depending on whether the crystal is included. Measure with calipers if thickness matters to you.
Subdial function is the first check
Low-cost Speedmaster Reduced replicas use movements where one or two subdials are decorative. Ask which subdial carries the running seconds. On a correct layout the hand at 9 sweeps once per minute in small steps, the hand at 3 advances once per minute, and the hand at 6 jumps once per hour. If all three hands sweep together, the watch has a single-seconds movement behind a printed dial.

Case thickness and pusher feel
The chronograph module stacks on top of the base movement, so the original stays near 12 mm. Replicas built on a Valjoux 7750 or a clone of it run 13.5 mm to 15 mm. Measure the case with the crystal fitted. Pushers should start and stop with light pressure and reset to zero without creep. A pusher that travels halfway before engaging points to a module that is out of alignment.

Dial, crystal and bezel
Print on the original is thin and sharp. Look at the OMEGA wordmark and the Speedmaster line below it: letters on a good replica hold a consistent stroke weight, with no fuzz at the edges. Applied indices sit flat and carry lume in the center. The hesalite crystal shows a warm tint at the edge and no printed sapphire marking. The bezel insert reads TACHYMETRE with the accent, and the dot sits above the 90 mark.
Bracelet and caseback
Lug width is 18 mm. End links should meet the case with no gap at the top or bottom edge. The clasp should close in one click with no rattle. Caseback engraving on the original is stamped to a depth you can feel with a fingernail. Laser etching on replicas is shallow.
What stays unknown
Replica factories change movements and suppliers without notice. A listing page can describe an earlier batch. Ask the seller for photos of the unit in stock, including the movement and a caliper reading across the case.
