A replica Constellation 151.10.39.50.06.001 is a copy of a 39 mm Omega Constellation, and a good first copy matches the case profile, claw bezel, dial text, and bracelet taper close enough that most people need a loupe to spot the difference. The reference number works as a spec sheet, so read it before you look at a single photo. If a listing contradicts the build that the number describes, the listing is wrong.
What does the reference 151.10.39.50.06.001 tell you?
Omega writes references in blocks, and each block carries one piece of information. The opening digits describe the case and bracelet combination in the catalog, the pair 39 is the case diameter in millimeters, and the 50 block points to an automatic movement family with a date. The .06.001 tail marks the dial variant and the production version.
- 151 case and bracelet combination
- 10 material and finish grouping
- 39 case diameter in millimeters
- 50 automatic movement family with date
- 06.001 dial code and version code
This matters because sellers mix photos from different references all the time. A 41 mm case shot attached to a 39 mm reference number is the first sign of a listing copied from another store page. Ask for the case diameter in writing and compare it to the number.
What should you check first on a first copy Constellation?
Four areas decide whether a first copy looks right on the wrist: the bezel, the dial, the bracelet, and the movement inside. Work through them in that order.
Bezel and case
The Constellation bezel carries claw marks at 3 and 9 o'clock, and those claws sit flat and sharp on the genuine watch. Copies with thick, rounded claws look wrong from arm's length. Case thickness is the other giveaway, since cheap builds run 1 mm to 2 mm deeper to fit an oversized movement.
Dial and hands
Check the star emblem above the 6 o'clock marker, the applied hour markers, and the crispness of the printing. Good first copies use applied markers with polished edges and a dial surface that shifts tone in daylight. Printed markers with flat paint are the clearest sign of a low tier build.
Bracelet and clasp
End links should sit flush against the case with no visible gap. Run a fingernail along the join. The clasp should close with one firm click, and the engraving should be stamped, not laser printed with a faded outline.
Movement
Wind the crown and listen. A decent automatic rotor turns with a soft, even sound, and the date flips within a few minutes of midnight. A rattling rotor or a date that creeps from 8 p.m. onward points to a low-grade movement.
Which replica grade should you buy?
First copy watches come in three rough tiers, and the tier matters more than the seller's marketing language.
- Entry tier: quartz movement, mineral glass, stamped bracelet, hollow end links. Fine as a beater, wrong as a Constellation.
- Mid tier: automatic movement such as a Seiko NH35 or Miyota 9015, sapphire crystal, solid end links, screw pins. This is where most buyers should start.
- Top first copy: decorated automatic movement, near-genuine case thickness, hand-finished bracelet, correct dial texture and font weight. The closest match short of the real watch.
What does a replica Constellation 151.10.39.50.06.001 cost?
Prices track the movement and the bracelet, not the brand name on the dial.
- $60 to $120: quartz, mineral glass, hollow bracelet
- $150 to $320: automatic NH35 or 9015, sapphire glass, solid end links
- $350 to $600: high-grade first copy with a decorated movement and genuine-spec dimensions
A price far below those bands means the seller cut the movement or the crystal, no matter what the product page claims.
How do you vet a seller before paying?
- Ask for dated photos of the exact watch you will receive, not catalog renders.
- Ask which movement sits inside and how many hours of power reserve it holds.
- Confirm the case diameter is 39 mm and the lug width matches the reference.
- Check the return window and whether shipping is tracked.
- Pay with a method that carries buyer protection.
Frequently asked questions
Is a replica Constellation the same size as the genuine watch?
A mid tier or top tier copy in this reference measures 39 mm across the case, matching the original. Entry tier copies often run 40 mm or more because the case is built around a generic movement.
Will the bracelet fit my wrist?
Most first copy Constellations ship with enough links for a 7.5 inch wrist, and many include spare links. Ask for the link count before you order if your wrist measures over 7.5 inches.
Can a watchmaker service a first copy?
Yes, if the movement is a known caliber such as an NH35, a 9015, or an ETA clone. Independent shops service those parts without trouble. A no-name quartz module is often cheaper to replace than to repair.
How do I spot a listing that will not match the photos?
Look for stock renders, missing case measurements, and photos that show several references in one gallery. A seller who answers spec questions in one sentence is a better bet than one who replies with a paragraph of praise.
Care and upkeep for a first copy Constellation
Treat the watch like any automatic: keep it away from magnets, avoid swimming unless the seller states a tested depth rating, and wipe the case and bracelet with a dry cloth after wear. An automatic movement in this tier runs best with a service every four to six years. Store it on a soft pad so the bracelet does not pick up desk scratches.
Two things decide whether you are happy with the purchase: the reference number matches the build you receive, and the movement inside is a caliber a watchmaker can work on. Get both in writing before you pay.
