Short answer: yes, the Fifty Fathoms Full Moon replica exists and it looks convincing on a wrist, but the moon phase window is almost always the weakest part of the watch. On most copies that aperture hides a 24-hour day/night disc that spins once a day, not a 29.5-day lunar cycle. Buy it as a good-looking dive watch with a busy dial and you will be pleased. Buy it expecting a working complete calendar and you will be disappointed.

What the real watch actually is
The genuine piece people mean by "Full Moon" is the Fifty Fathoms Bathyscaphe with a complete calendar and moon phase. Blancpain builds it around a 43mm case, a ceramic bezel insert, and an in-house automatic calibre that drives day, date, month, and a true lunar disc. The layout is the tell: subdials or apertures for the calendar functions, a moon window near 6 o'clock, and a small seconds hand. Once you know that arrangement, replica dials are easier to read at a glance.
Fifty Fathoms Replica Full Moon Guide: What to Check
Where replicas get it right
- Case silhouette and lug profile. The 43mm Bathyscaphe shape is copied well because it is simple geometry.
- Ceramic bezel inserts. Modern reps print and polish these to a standard that fools most people at arm's length.
- Dial texture and printing. Sunburst finishes and applied markers are close on the better tiers.
- Sapphire crystal with inner anti-reflective coating. Cheaper builds skip the AR and the dial looks flat as a result.
- Strap and bracelet options. Sailcloth, rubber, and steel versions all exist in the rep world.
Where they fall short
The moon phase is the headline problem. A real moon disc advances roughly once every 24 hours and 50 minutes, so over a month it drifts through its cycle. Rep discs commonly rotate on a 24-hour gear, which means the moon and stars are in the same position every night. Watch the window for a week before you decide.

Calendar fonts and window edges are the second issue. Genuine date and day text is crisp and sits square in the aperture. On reps the printing is often slightly bolder and the cutouts can be off-center by a hair. Crown feel matters too. A gritty or wobbly crown on a dive watch is a bad sign for the whole build, and the screw-down threads are worth testing twice.

Bezel action separates tiers more than any photo will show. Count the clicks. A genuine dive bezel is firm with no back-play. Many reps wobble a degree or two and the triangle marker drifts off 12.
Movements you will run into
Most Fifty Fathoms Full Moon replicas use a Japanese or Chinese automatic base with a calendar module bolted on top. That module is where reliability drops. Pushers feel mushy, the date can change gradually between 10pm and 2am instead of snapping at midnight, and the moon disc is the part that gets faked. A small number of higher-end builds use a decorated clone movement, which mostly buys you nicer rotor engraving you will never see on the wrist.
What I check before buying
- Measure your wrist against 43mm. This is a big watch and it wears bigger than the number suggests.
- Ask for a video of the date flipping, not just still photos.
- Ask how long the moon window takes to change. If the seller will not answer, assume a 24-hour disc.
- Check bezel alignment at 12 in a straight-on shot.
- Confirm the crystal has AR coating on the inside.
- Assume the water resistance claim is optimistic. Do not swim in a replica.
Price expectations
Budget builds under roughly $150 usually pair a rough case with the fake moon disc. The $250 to $600 band is where the case, dial, and bracelet start to feel like a real object. Above that you are paying for movement finishing and factory name, not for a working lunar complication. Nothing in the replica market gives you a true moon phase at a bargain price, so set your expectation on looks rather than function.
Bottom line
The Fifty Fathoms Full Moon replica is worth owning for the case and dial work. Treat the moon phase as a design element. If a functioning complete calendar is the reason you want the watch, save for the real thing, because no copy at any price delivers that part honestly.
