A replica Constellation 131.13 is a copy of a vintage Omega Constellation, and the number matters more than most buyers realize. If you are shopping one, check three things first: case size and thickness, dial printing on the pie-pan surface, and the movement inside. A rep that nails the case proportions but runs a cheap quartz module will feel wrong on the wrist the moment you pick it up. The good ones use an automatic movement, keep the case near 35mm across, and get the star logo and Constellation script sharp under a loupe.

What the 131.13 Reference Tells You
Reference codes from this era are shorthand for a case shape, a dial layout, and a movement family. When a listing says 131.13, the seller is pointing at the classic mid-century Constellation look: a thin gold-capped or steel case, slim lugs, a domed crystal, and a dial with a raised pie-pan edge. That shape exists because the dial sat over a thick automatic movement, so the outer ring dropped down to clear the case.
The Ultimate Guide to the 131.13 Constellation Fake Watch
Replica makers copy that profile in two ways. Some press a flat dial and fake the pie-pan with printed shading. Others machine a real stepped dial. You can tell them apart by tilting the watch under a light. A real step casts a hard shadow line; printed shading just looks darker.
How to Choose the Best Constellation 131.13 Fake Watch
Case and Dial Details Worth Checking
- Diameter should land around 34.5 to 35.5mm for a vintage-correct feel. Bigger than 36mm reads as a modern reinterpretation.
- Thickness around 10 to 11mm. Anything over 12mm sits high and looks bulky.
- Lug width of 18mm is typical. Odd sizes make strap swapping a headache.
- Dial text: the star logo sits above the brand name, and "Constellation" runs in a thinner script than the printing around it.
- Applied markers should have crisp edges. Look for glue haze or uneven polishing.
- Date window at 3 o'clock should be square-cut with a clean aperture, not a rough punched hole.
Movement: Where Most Replicas Fall Short
This is the deciding factor for me. A decent replica Constellation 131.13 will run a Miyota 9015, an ETA 2824 clone, or an ST21-style automatic. Those sweep smooth, hack, and hold time well enough for daily wear. Cheaper builds hide a quartz module behind a decorated rotor plate. Pop the caseback or ask for a movement photo before you pay. If the second hand ticks once per second, it is quartz, no matter what the listing claims.

Service history rarely exists on replicas, so plan on a regulation within the first year if timekeeping drifts. Local watchmakers will usually work on common clone movements without asking questions.
Bracelet and Finishing
Vintage Constellations came on beads-of-rice and brick-style bracelets, often gold-capped rather than solid gold. Replica bracelets vary a lot. Check the end links for gaps against the case, then flex the bracelet and listen. Squeaky links mean thin pins and stamped clasps. Gold plating on a bad rep wears through at the clasp within months.
Quick Buying Checklist
- Confirm the movement type with a photo or video.
- Ask for the exact case diameter and thickness in millimeters.
- Request close-ups of the dial step, date window, and caseback engraving.
- Compare the crown size and shape to reference photos of the original.
- Check return policy before shipping, especially for overseas sellers.
None of this makes a replica into an original, and it should not. What it does is separate a build that looks right on a desk from one that looks right on a wrist. Get the case proportions and the movement correct, and the rest of the watch usually follows.
