A Blancpain 50 Fathoms copy watch is a replica built to look like the Fifty Fathoms diver, not a watch made by Blancpain. Good copies match the case size, bezel action, and dial layout of the original, but they run third-party movements and carry no warranty. They are also not pressure tested, so they stay out of the water.
What Is a Blancpain 50 Fathoms Copy Watch?
The name covers a wide range of watches, from budget quartz models to automatic builds with sapphire crystals. What they share is a target: the Fifty Fathoms silhouette.

- What it is: a third-party watch styled after the Blancpain Fifty Fathoms.
- What it is not: a Blancpain product, a collector piece, or a dive tool.
- Why people buy one: the dive-watch look without the five-figure price of the genuine article.
The Genuine Fifty Fathoms in Brief
Blancpain released the Fifty Fathoms in 1953 for French combat swimmers. Watch historians count it among the first modern dive watches, with a rotating bezel, a large triangle marker at 12, and a case rated to 50 fathoms (about 91 meters). Early dials carried a moisture indicator at 6 o'clock that changed color if water got inside.
Blancpain Fifty Fathoms Replica Guide: Details, Sizing, Reality
Today's Fifty Fathoms Automatique uses the in-house Calibre 1315: 120 hours of power reserve and a silicon balance spring. The case measures 42.3 mm. The Bathyscaphe line sits near 43 mm with a cleaner dial and a sportier feel.
What Separates a Good Copy From a Cheap One
Price tells you little. Detail tells you plenty. Four areas decide whether a copy looks right on the wrist or looks off from a meter away.
Case and Bezel
Measure the case, do not trust the listing. A 42.3 mm Automatique copy should measure 42.3 mm across the case, not across the bezel. Lugs should curve down, crown guards should sit flush, and the bezel should click in firm, even steps. A bezel that wobbles or lines up off-center at 12 is the fastest tell.
Dial Layout, Printing, and Lume
Look at the font weight of the numerals and the gap between the date window and the markers. Marker edges should be polished, not painted. Lume should glow green and fade over hours; a copy that glows for ten minutes uses cheap paint.
Movement
- Seiko NH35: common, sturdy, easy for a watchmaker to service.
- Miyota 9015: thinner, with a smoother sweep.
- ETA 2824 architecture clones: closer to a Swiss layout, and quality varies from factory to factory.
Check three things before you pay. The seconds hand should sweep, the crown should hand-wind, and the date should flip near midnight rather than at 3 a.m.
Crystal, Finish, and Bracelet
Genuine Fifty Fathoms watches use sapphire with an inner anti-reflective coating, so reflections look faint and the dial stays dark. Brushed and polished surfaces should meet at crisp lines. Bracelet end links should sit flush against the case with no gap.
Water Resistance: The Big Caveat
Copy watches are assembled outside a controlled line and are not pressure tested. Gaskets may be present, but nobody has verified them. Do not swim, dive, or snorkel with a copy, and keep it out of hot showers, where steam can fog the crystal.
A listing that promises 300 meters of water resistance is selling a marketing line. A pressure test at a local shop proves one sample on one day, not the watch that arrives at your door.
How Much Does a Blancpain 50 Fathoms Copy Cost?
There is no standard price. Cost tracks the movement inside and the hours spent on finishing. Budget quartz copies sit at the bottom of the market, automatic copies with a clone movement and a sapphire crystal sit in the middle, and high-end builds sell for several hundred dollars. A genuine steel Fifty Fathoms runs into five figures, and that gap is the whole reason the copy market exists.
Legal Points and a Cleaner Alternative
Counterfeit watches infringe trademarks, and in the US, importing one is illegal. Customs can seize the package, and you have no recourse when it happens. Reselling a copy while claiming it is genuine is fraud, and that charge carries real penalties.
A legal option exists: the homage watch. Homage brands use the dive-watch formula (rotating bezel, steel case, dark dial) under their own name and logo. You give up the trademark on the dial and gain a warranty, parts support, and no customs risk.
FAQ
Is a Blancpain 50 Fathoms copy watch the same as the real one?
No. It shares the look and nothing else: no in-house Calibre 1315, no Blancpain warranty, no service network, and no resale value.
Will a watchmaker service a copy?
Blancpain will not touch it. Independent shops often will, because NH35 and ETA-style movements use standard parts. Expect to pay labor plus parts, and expect some shops to decline the job.
How can I spot a copy?
Check the caseback engraving, the movement finish on a display back, the bezel action, and the paperwork. Serial numbers on copies repeat across batches, and caseback text sits shallow or off-center.
Which size should I pick?
Match the watch to your wrist, not to a spec sheet. A 42.3 mm case suits wrists from about 6.75 inches and up. Under that, a 42 mm dive watch overhangs the wrist bones, and a strap fits better than a steel bracelet.
Do copies hold value?
No. A copy resells for less than you paid, and most watch forums block listings for counterfeits out of hand.
