Fake Blancpain Fifty Fathoms 5015 watches exist. The 5015 is a current dive watch with a 45 mm case, 300 m water resistance, and the in-house caliber 1315. No replica carries that movement. Replica listings run $250 to $700. Genuine examples list at about $16,000 and up.
What the reference 5015 is
Blancpain built the first Fifty Fathoms in 1953 for French combat divers. The 5015 is the modern 45 mm automatic version. Specs: 300 m water resistance, unidirectional bezel with a sapphire insert, screw-down crown, caliber 1315 with three series-coupled barrels and 120 hours of power reserve, 227 parts, 35 jewels, silicon balance spring, 18k gold rotor. Strap options include sail canvas, rubber, and steel bracelet.
Where fakes appear
Listings show up on marketplaces, social media, and chat groups. Sellers reuse photos from other auctions. Some drop the brand name to dodge filters. Prices sit at $250 to $700. Pre-owned genuine 5015 prices sit near the retail range, so a low number is the first signal.
Checks on the outside
- Case: 45 mm wide. Replica cases measure 1 mm to 2 mm off, and lug shapes change.
- Bezel: sapphire insert with lume plots. Fakes use mineral glass or painted acrylic.
- Crystal: double-domed sapphire, anti-reflective coating on both faces. Fakes have one coat or none.
- Dial: applied indices with polished edges, sharp printed text. Fakes show fuzzy print and flat markers.
- Crown: screw-down with the JB logo in relief. Stamped logos sit shallow and lose detail.
- Caseback: engraving depth, font, and serial placement. Fake cases use laser etching with a thin line.
Checks on the movement
Ask for a photo of the caliber through the caseback. Caliber 1315 runs at 28,800 vph and holds 120 hours. A generic replica movement holds 38 to 42 hours. Rotor engraving on fakes shows shallow cuts and a plated finish.
Papers and serial
Fake kits include a warranty card, box, and invoice. A serial check with Blancpain confirms the model and year. Service records come through the Swatch Group network. Ask the seller for a dated photo of the caseback and the card together.
US legal position
Counterfeit watches are illegal to import and sell in the United States under 19 U.S.C. § 1526 and the Trademark Act. US Customs seizes shipments. Reselling a counterfeit is trademark infringement. A US seller of a 5015 copy faces seizure, fines, and civil claims.
