Short Answer
A replica Blancpain 5200 is a counterfeit of the Fifty Fathoms Bathyscaphe Chronograph Flyback, reference 5200. The genuine watch arrived in 2014. Case size is 43.6 mm, thickness is 15 mm, water resistance is 300 m, and the movement is calibre F385, an automatic flyback chronograph with a column wheel, vertical clutch, silicon balance spring, 36,000 vibrations per hour, and a 50-hour power reserve. Retail sits near $16,000 USD. No copy uses that movement. Replicas run on third-party automatic chronograph calibres, and the flyback pusher at 4 o'clock does nothing on most of them.
Genuine Specs to Compare
- Case: 43.6 mm steel, titanium, or ceramic, about 15 mm thick
- Bezel: ceramic insert, 60-minute scale, unidirectional
- Subdials: 30-minute counter at 3, small seconds at 9
- Date: window at 4:30 on several versions
- Strap: sail canvas, NATO, or steel bracelet
- Caseback: sapphire display, rotor in gold or gray
Reference codes start with 5200 and then carry case and strap codes. Confirm the full number with Blancpain before you compare a listing against it.
Where Copies Fall Short
Thickness is the first tell. Most copies run 1 mm to 3 mm thicker than the 15 mm original, so the watch sits high on the wrist. Subdial spacing differs because the movement is different. Date font, date position, and bezel insert color vary from batch to batch. The ceramic bezel click is soft on low tiers. Lume fades in 1 hour to 3 hours. Caseback engraving is shallow and the rotor decoration is rough under a loupe. Crystal height above the bezel is often wrong by a fraction, which changes the side profile.
Price Tiers
- $60 to $150: quartz or low-grade automatic, mineral glass, chronograph pushers that do not function
- $200 to $400: automatic chronograph with working start, stop, and reset, 316L steel, sapphire on some listings
- $450 to $900: higher tier copies, closer case shape, decorated rotor, thickness still off
A listing that claims a Swiss ETA 7750 inside a $300 watch is false. That movement alone costs more than the watch.
US Legal Position
Counterfeit watches are illegal to traffic in, import, or sell in the United States. 18 U.S.C. § 2320 covers counterfeit goods trafficking, and CBP can seize shipments at the border. Blancpain does not license replicas. Any 5200 sold as a replica is counterfeit, and resale is a federal offense.
How to Read a Listing
Ask for case diameter and thickness measured with calipers, a photo of the movement and rotor, a video of chronograph start, stop, and reset, and a photo of the caseback. A seller who cannot send caliper photos is guessing. Group-buy QC photos show one watch, not the unit you receive. Wire and crypto payments remove the refund path. Stock photos and the word "mirror quality" carry no information.
