A fake Fifty Fathoms 1953 Bathyscaphe is a replica of Blancpain's first dive watch line, built to copy the look of the 1953 Fifty Fathoms and the smaller 1956 Bathyscaphe. The original Fifty Fathoms used a case near 41 mm, and the Bathyscaphe near 38 mm, so a replica should match one of those two sizes rather than a generic 44 mm diver case.

This guide covers the parts that decide whether a replica looks right on the wrist: case shape, bezel action, dial print, hand shape, movement, and strap. Each point applies to both the Fifty Fathoms style and the Bathyscaphe style.

What are the 1953 Fifty Fathoms and the Bathyscaphe?

The Fifty Fathoms arrived in 1953 as a tool for French combat swimmers. It carried a water resistance rating of 50 fathoms (about 91 meters), a rotating bezel, and an automatic movement at a time when most divers relied on hand-wound watches.

The Bathyscaphe came three years later as a smaller, civilian version, named after the deep-sea submersible of Auguste Piccard. It dropped the moisture indicator that sat at 6 o'clock on some early Fifty Fathoms dials and came in a case near 38 mm.

Fake Fifty Fathoms 1953 Bathyscaphe Review: Authenticity Compared

  • Fifty Fathoms (1953): case near 41 mm, automatic movement, locking dive bezel, moisture indicator on early dials.
  • Bathyscaphe (1956): case near 38 mm, cleaner dial, aimed at daily wear as much as diving.
  • Both: black dial with large lume plots, steel case, screw-down caseback.

Blancpain brought the Bathyscaphe name back in 2013 with a 43 mm case. That matters for buyers because many replicas sold as a 1953 Bathyscaphe copy the 2013 watch, not the 1956 one.

What separates a good replica from a cheap fake?

The gap between a $100 fake and a $500 replica shows up in five places. None of them involve the logo on the dial.

Case and bezel

Measure the case before you trust a listing. A 1953 copy should sit near 41 mm across, and a Bathyscaphe copy near 38 mm, both without the crown.

  • Lugs should curve down and finish with a bevel, not a blunt slab.
  • The bezel should turn with firm clicks and no back-play.
  • Bezel insert print should be thin and even, with the pip aligned at 12.
  • Crown guards, if present, should match the reference you chose.

Dial and hands

Dial print is the first thing a collector checks. Sharp text, even lume plots, and a clean moisture indicator circle (where the reference has one) point to a careful build.

Hand shape is the second. The 1953 used a set profile that many low-cost replicas replace with generic sword hands, and that swap is easy to spot in photos.

Lume and aging

Vintage Fifty Fathoms dials show aged lume that shifts to cream or orange. Replicas either use a pale mix that looks new or an overdone yellow that looks painted on, so compare the tone against reference photos before you buy.

Movement

Movements range from a basic Asian automatic to a Miyota 9015 or a clone of a Swiss design. Ask for the movement name in writing before you pay.

  • Budget builds: Asian 8215 or similar, 21,600 vph, plain finish.
  • Mid builds: Miyota 9015 or Seiko NH35, both easy to service.
  • Top builds: decorated clone movements with a rotor engraved to look Swiss.

A decorated rotor does not make a movement Swiss. Judge the beat rate, the winding feel, and the service record instead.

Strap and clasp

The 1953 Fifty Fathoms shipped on a rubber strap made for diving, and the Bathyscaphe on leather or a fabric strap. Replicas often arrive with a cheap rubber band that smells of plastic, which is a sign of cost cutting elsewhere.

Which size should you buy?

Pick the size of the reference you want to copy, not the size that looks big in photos. A 38 mm Bathyscaphe copy wears like a vintage watch, and a 41 mm Fifty Fathoms copy sits like an early dive tool.

If a seller lists a 1953 Bathyscaphe at 43 mm, that watch copies the 2013 revival. There is nothing wrong with that, but the listing should say so.

How much should a fake Fifty Fathoms 1953 Bathyscaphe cost?

Price tracks materials and finishing, not the brand name on the dial. As a general guide:

  • Under $150: mineral glass, stamped case, basic automatic or quartz movement.
  • $200 to $400: sapphire crystal, solid case build, Miyota or Seiko movement, working dive bezel.
  • $450 and up: clone movement, closer case profile, anti-reflective sapphire, better lume.

Anything above $900 deserves a video of the actual watch before you send money. At that price the seller should show the movement, the caseback, and the bezel action.

How do you check a seller before buying?

Ask for photos and video of the exact watch you will receive, not catalog images. Then run through this list.

  1. Confirm the case diameter and movement model in writing.
  2. Watch a video of the second hand sweep and the bezel click.
  3. Check the caseback engraving for depth and font.
  4. Read the return policy and the shipping method.
  5. Pay with a method that offers buyer protection.
  6. Look for buyer photos in reviews, not stock renders.

Common questions about the replica Fifty Fathoms Bathyscaphe

Is a replica water resistant?

Stated ratings are claims, not test results. Have a watchmaker pressure-test the case before you swim with it, and expect to replace the caseback gasket on a cheap build.

Can a jeweler tell it is a fake?

A trained eye can spot a replica from the caseback, the movement finish, and the dial print under a loupe. At arm's length, most people will not notice.

Can a replica be serviced?

Yes, if it uses a common movement. Miyota, Seiko, and ETA-style parts are cheap and any independent watchmaker can handle them.

Which reference is easier to copy?

The Bathyscaphe is the simpler target because its dial has fewer details. The 1953 Fifty Fathoms demands a correct bezel lock, moisture indicator, and hand set, so fewer replicas get it right.

Bottom line

Judge a fake Fifty Fathoms 1953 Bathyscaphe by case size, bezel feel, dial print, and movement name. Get those four right and the watch reads as a vintage dive piece from across a table.
