The short answer

151.10.39.50.06.001 is an Omega product code. It is not a Rolex reference. Omega uses 14-digit codes in this format for the Constellation line. Counterfeit sellers copy the same string into listings for fake watches. The code proves nothing about a watch on its own. Copyists print it on cases, hang tags, and cards.

This article could not confirm that 151.10.39.50.06.001 sits in Omega's current catalog. Check the number with Omega or an authorized dealer before money changes hands.

How the 14 digits break down

Omega codes follow a set pattern: AAA.BB.CC.DD.EE.FFF. Each group points to a part of the watch.

  • AAA: collection or case family. Resale listings attach the 151 block to Constellation models. Omega publishes no public list that confirms the block.
  • BB: case material. 10 means stainless steel.
  • CC: case diameter in millimeters. 39 means 39 mm.
  • DD: movement group. The meaning of 50 is not documented in public sources.
  • EE: dial color or dial variant. The meaning of 06 is not documented in public sources.
  • FFF: version number. 001 marks a first version.

Omega does not publish a full key for every group. Treat any decoder that claims total coverage with doubt.

Why fakes carry this number

A reference number is the cheapest part of a counterfeit to copy. It costs nothing to stamp 151.10.39.50.06.001 on a caseback. A buyer searches the string, lands on a listing, and reads the match as proof. The box, the manual, and the warranty card come from the same workshop. Rolex counterfeiters use the same method with five-digit and six-digit model numbers.

Checks that catch a copy

  • Movement: Master Chronometer Constellations run Co-Axial calibres with a silicon hairspring and 15,000 gauss magnetic resistance. Most replicas run Asian ETA clones or quartz.
  • METAS card: each certified watch ships with a card that lists a unique test number and the results of eight tests.
  • Caseback: look at the engraving and the medallion under 10x magnification. Laser marking is crisp. Stamped fakes show rounded edges and uneven depth.
  • Weight: steel, gold, and ceramic have different densities. Plated brass and zinc alloy come in light.
  • Dial: applied indexes sit level. Print shows no bleed under a loupe.
  • Price: if the number is a fraction of retail, the watch is not genuine.

US law

19 U.S.C. 1526 bars import of goods that carry a counterfeit mark. US Customs and Border Protection seizes such shipments and can destroy the goods. A buyer can lose the watch and the money. A seller who passes a fake as real faces civil claims and, in some cases, criminal charges.
