What the Speedmaster Reduced Is
The Speedmaster Reduced ref. 3510.50 has a 39mm steel case and an automatic movement. Omega built it around an ETA base calibre with a Dubois-Depraz chronograph module stacked on top. The date sits at 3 o'clock, and a corrector pusher sits at 10 o'clock. The 3510.50 uses a Hesalite crystal. The later 3539.50 uses sapphire. Omega stopped production around 2009.
Buyers pick the Reduced for the case size. A 39mm chronograph fits a 6.5 inch wrist. The Moonwatch does not. That size gap is the reason the model still sells on the pre-owned market.

Two problems come with the model. The module adds service cost. Not every watchmaker will touch a piggyback chronograph. Parts supply for a discontinued Omega calibre is limited. Confirm service options before you buy.
First Pick: Omega Speedmaster Professional 3861
The current Moonwatch is the direct upgrade. The case measures 42mm. The 3861 movement is manual wind, co-axial, and certified as a Master Chronometer. Power reserve is 50 hours. Water resistance is 50m. Hesalite and sapphire versions exist.
The trade-off is size and thickness. A 42mm case with a tachymeter bezel wears larger than the number suggests. Try one on before you commit. The upside is a current production watch with full factory service support.
Option 2: Omega Speedmaster 38
The Speedmaster 38 keeps the smaller case idea. The case measures 38mm. It runs an automatic movement and carries a date at 6 o'clock. Dial layouts vary by reference, including two and three register versions. This is the closest current-production match to the Reduced brief.
Case shape differs from the Moonwatch. The lugs and bezel are softer. Some buyers see that as a departure from the original design. Check the reference number against the spec sheet.
Option 3: Tudor Black Bay Chrono
The Black Bay Chrono has a 41mm steel case, a 200m water rating, and the MT5813 movement. Power reserve is 70 hours. It carries a tachymeter bezel and a screw-down pusher layout. Build quality per dollar is strong. The case is thick, and the dial is busy.
Option 4: Breitling Navitimer B01 Chronograph 41
The Navitimer 41 uses the in-house Breitling 01 movement with a column wheel and vertical clutch. Power reserve is 70 hours. Water resistance is 30m. The slide rule bezel is the defining feature. It adds visual noise and cleaning work.
Note on Replica Watches
Counterfeit watches are illegal to import into the United States for resale. US Customs and Border Protection seizes them. A replica has no factory service path, no genuine parts, and no resale value. Movement finishing and case tolerances do not match the original. If the goal is a 39mm automatic chronograph, the pre-owned Reduced or the Speedmaster 38 is the honest route.
Sizing and Service Checklist
- Measure your wrist in millimeters, then add 6mm to 8mm for fit.
- Ask for a service history on any Reduced. The module is the cost item.
- Confirm water resistance with a pressure test, not a sales claim.
- Check lug width before buying straps. The Reduced uses 18mm lugs.
