Short answer
A replica Blancpain 5221 sells between $120 and $600 at most dealers. The case is stainless steel. The crystal is sapphire on mid-tier and top-tier builds. The movement is an automatic copy of the ETA 2824 or a Seagull ST2130. No replica matches the finishing of the genuine watch. Public documentation on the Blancpain 5221 reference is thin, so confirm the exact model with the seller before you pay.
What the reference number tells you
Blancpain groups references by collection. Villeret covers dress watches. Fifty Fathoms covers dive watches. Bathyscaphe sits under Fifty Fathoms. The 5221 number does not appear on the current catalog pages that most dealers cite. Some listings describe it as a Villeret style three-hand watch with a date. Others describe a moon phase. Treat the photos as the source, not the number.
Movement
- A2824: a Chinese-made copy of the ETA 2824-2. 25 jewels. 28,800 vibrations per hour. Power reserve near 38 hours.
- Seagull ST2130: made by Tianjin Seagull. Same beat rate. Power reserve near 40 hours.
- Miyota 9015: a Japanese movement. 24 jewels. Power reserve near 42 hours.
- Decorated rotor: engraving and Geneva stripes applied for looks. It does not change function.
Ask the seller for a photo of the movement with the caseback open.
Case and dial checks
Measure the case with calipers. Listings inflate size by 0.5mm to 1mm. Check lug width. Most builds use 20mm or 22mm straps. Look at the date window. A misaligned date sits off-center in the aperture. Check the printing on the dial under a loupe. Thin or fuzzy text is the most common tell. The crown should screw down without grit.
Price tiers
- Under $100: mineral glass, quartz or low-grade automatic, plated case.
- $120 to $250: 316L steel, sapphire on some models, A2824 or ST2130.
- $250 to $600: best finishing, sapphire on both sides, better dial print, closer case profile.
Prices move with the exchange rate and with factory output. Stock comes and goes.
Where replicas fall short
Genuine Blancpain movements carry finishing that machines in the replica price range do not reproduce. Bridges on the genuine caliber are hand-finished with chamfered edges and polished screws. Straight-grain and circular-grain patterns differ. Water resistance is a second gap. A replica rated at 50m is not pressure tested. Do not swim with it.
Questions for the seller
- Which factory made it?
- Which movement is inside?
- Is the crystal sapphire on the front and the back?
- Is the case 316L or 904L steel?
- Do you have photos of the actual watch, not stock images?
Any seller who refuses photos of the real unit is not worth the order.
