Top pick: the 39 mm automatic replica Speedmaster Reduced with a working 3-6-9 chronograph layout, a domed crystal, and a case under 14 mm thick. It copies the proportions of the real Omega ref. 3510.50 instead of shrinking a 42 mm Moonwatch, so it wears correctly on an 18 mm bracelet. Start there, then choose a finish from the three options below.

Why the 39 mm automatic version wins
The genuine Speedmaster Reduced is a 39 mm watch with a slim automatic chronograph movement, and that is the hardest part of the design to copy. Many factories solve the problem by hiding a quartz module or a thicker 7750-based movement inside, and the extra 2 to 3 mm shows on the wrist right away. The best replica keeps the case at 39 mm, the thickness near 13 mm, and the lug width at 18 mm.

What separates a good Speedmaster Reduced replica from a bad one?
- Case size and thickness: 39 mm wide and 12 to 13 mm thick. Anything past 14 mm reads wrong next to a real one.
- Subdial function: the 3-6-9 registers should run as real chronograph counters, not printed or frozen dials.
- Crystal: domed hesalite on 3510.50-style builds, flatter sapphire on 3539.50-style builds.
- Bezel insert: sharp tachymeter numerals, a matte black base, and a dot aligned with the 90 marker.
- Bracelet: 18 mm end links with a taper, solid links, and a signed clasp.
- Dial printing: correct text weight for the branding, plus an honest date window at 3 or none at all.
Speedmaster Reduced replica options compared
1. Top tier: 39 mm automatic, hesalite, steel bracelet
This is the one to buy first. It pairs correct 39 mm dimensions with a real chronograph movement, a stepped dial, and a bracelet that tapers the way the original does. Expect the closest match in wrist feel and the highest price of the three.
2. Mid tier: 39 mm automatic, sapphire, leather strap
A solid second choice when you want a scratch-resistant crystal and a dressier look. Case width stays correct, but the movement is usually a simpler automatic and the pusher feel is softer.
3. Budget: quartz, 40 mm case
Cheapest and easiest to live with, yet the least convincing. The sweeping seconds hand is missing, the case often runs a full millimeter wide, and the subdials are decorative on many examples.
Is the Omega Speedmaster Reduced 39 mm or 42 mm?
It is 39 mm. The reduced line sits about 3 mm smaller than the standard Moonwatch Professional, which changes how it sits on smaller wrists and under a cuff. Any replica listed at 42 mm is a different watch wearing the same name.
Which movement should a replica use?
A modified automatic chronograph with a Dubois-Depraz-style module layout gives the right subdial positions and keeps the case thin. A quartz movement can still keep time well, but it fails the smooth sweep test within seconds of a close look. Movement choice drives roughly half the price gap between the tiers above.
Before you buy
Replica watches sit in a legal gray area, and trademark law varies by country, so check local rules before ordering. Buy from a seller with clear photos of the actual watch, a stated movement, and a return window. Ask for a wrist shot with a ruler in frame so you can verify the 39 mm case and 18 mm lugs yourself.
