A fake X Fathoms 5000 is a first copy of Blancpain's X Fathoms dive watch, usually sold under a listing name that blends the model with a reference or seller code. The genuine X Fathoms is a large dive instrument built around a mechanical depth gauge, so a good copy stands or falls on case size, dial layout, and whether that depth indicator actually moves.

What the Name X Fathoms 5000 Points To

Fifty Fathoms is Blancpain's long-running dive collection, and the X Fathoms sits at the extreme end of it. It arrived in 2011 as an oversized instrument watch with a depth gauge, a maximum-depth memory, and a case designed for serious underwater use rather than desk duty.

The "5000" part of the search term is where most confusion starts. It appears in reference numbers, stock codes, and marketplace listing titles far more often than it describes water resistance. The original X Fathoms is rated to a few hundred meters, not 5,000. When a listing claims thousands of meters of depth rating, read that as marketing copy, because no version of this watch was built to that figure.

Why This Name Is Searched So Often

  • The real watch is rare and expensive, which pushes buyers toward first copy options.
  • Seller listings mix model names and numbers, so the same watch appears under several titles.
  • Large dive watches are a style statement, and the X Fathoms silhouette is easy to recognize.
  • Buyers want to know whether the depth gauge on a copy is functional or just printed decoration.

What to Compare on a First Copy

Put two copies side by side and the differences show up fast. Focus on these points:

  • Case size and profile: the original is a very large watch, well over 50 mm across. A copy that measures much smaller will not wear the same or look right on the wrist.
  • Crystal: sapphire is the standard to aim for. Mineral glass scratches sooner and often shows a weaker anti-reflective coating.
  • Dial printing: check the spacing of the text, the thickness of the markers, and whether the lume is applied evenly.
  • Depth gauge hand: on a good copy it sits flush, sweeps without dragging, and does not wobble when the crown is turned.
  • Crown, pushers, and caseback: they should turn and press without grit, and the engraving should be crisp rather than shallow.
  • Strap or bracelet: look at the stitching, the buckle finish, and whether the end links sit tight against the case.

Checking the Movement

Many first copies use Japanese or Chinese automatic movements, and a few cheaper builds use quartz. Ask directly, then verify:

  1. Turn the depth gauge and confirm the hand tracks smoothly instead of jumping or sticking.
  2. Wind the watch gently and listen for a clean rotor spin with no scraping.
  3. Set the date and watch it change close to midnight without hesitation.
  4. Check the power reserve by leaving it off the wrist overnight.

A quartz copy will tick once per second. If the listing says automatic and the seconds hand ticks, the description is wrong.

Size and Wearability

This is not a subtle watch. The original was built for visibility underwater, so it sits high on the wrist and dominates a shirt cuff. If you have a wrist under about seven inches, try to see the copy in person or ask for wrist shots before ordering. Weight matters too. A hollow-feeling case is usually a sign of thinner steel and weaker finishing.

Price Tiers and What They Buy

First copy pricing generally splits into three levels:

  • Entry: correct overall shape, mineral glass, basic movement, lighter finishing.
  • Mid: sapphire crystal, better dial printing, smoother crown action, solid bracelet.
  • Higher: closer case proportions, decorated movement, sharper engraving, more convincing depth gauge feel.

Pay for the details you will actually notice on the wrist. Crystal quality and dial printing change the look more than an engraved rotor that nobody sees.

Questions to Ask Before You Buy

  • What is the exact case diameter and thickness?
  • Is the crystal sapphire or mineral?
  • Is the movement automatic, and which family is it?
  • Does the depth gauge hand move, or is it fixed?
  • Are there real photos of the actual watch, not stock images?
  • What is the return window if the size is wrong?

Living With a First Copy

Treat any first copy as a watch, not a dive tool. Rinse it with fresh water after contact with salt or chlorine, avoid pressing the pushers underwater, and keep it away from strong magnets. A large dive watch like this draws attention, so if the finish or the depth gauge feel disappoints you in person, return it while you still can.

Used as a style piece on dry land, a well-chosen fake X Fathoms 5000 can look convincing from across a table. The closer you inspect it, the more the case proportions, crystal, and gauge function decide whether it holds up.
