A fake drive 47mm is a replica watch advertised with a 47 millimeter case diameter and a cushion shaped case in the Drive style. The genuine Drive line is a dress-watch family, and its cases sit well below that figure, so a 47mm listing usually means the number was copied from another model, measured incorrectly, or belongs to a different watch altogether. Measuring the case yourself, or asking the seller for a caliper photo, is the quickest way to learn what the watch really is.
What 47mm Actually Measures
Case diameter alone does not tell you how a watch wears. Sellers often quote one number and leave out the rest, which is why two watches with the same 47mm rating can feel completely different on the wrist.
- Diameter: measured across the case at its widest point, with the crown excluded. A crown guard or an unprotected crown can add several millimeters to a careless measurement.
- Lug-to-lug: the distance from the tip of the top lug to the tip of the bottom lug. This is the figure that decides whether the watch overhangs your wrist.
- Thickness: a large case with a tall profile catches on shirt cuffs and sits high off the arm.
- Weight: a 47mm case in steel with a metal bracelet can feel noticeably heavier than the same watch on a leather strap.
Why the Number 47 Keeps Showing Up
Three things explain most listings with this figure.
How to Spot a Fake Drive 44mm Watch
- Spec sheets get recycled between listings, so a diameter from one model follows the photos of another.
- The seller measures across the crown or the crown guards instead of the case body.
- The words drive and dive are easy to mix up. Dive watches genuinely do come in 47mm sizes, so a search for one term can land you on the other.
If the photos show a slim dress case and the text says 47mm, the text is the suspect part.

How to Verify the Case Size
- Ask for a photo of digital calipers across the case back, positioned at the 3 and 9 o'clock sides.
- Ask for a lug-to-lug measurement with the strap removed.
- Request a wrist shot and the wrist size of the person wearing it, so you can compare against your own.
- Compare the dial proportions in the photos. A 47mm case makes a standard movement and dial look small inside a wide bezel or a broad chapter ring.
Fit Guide for a Large Case
As a rule of thumb, a wrist under about 6.5 inches will usually find a 47mm case wider than the flat top of the arm, so the lugs hang past the edges. Wrists around 7 to 7.5 inches can carry it if the lug-to-lug stays short. Above that, a 47mm case sits within the arm and looks proportionate. A curved case back and short lugs help more than a smaller diameter does.
What to Inspect on the Watch Itself
- Case finishing: check that brushed and polished surfaces meet in clean lines, with no soft or rounded edges.
- Crown action: winding and setting should feel smooth, with no grit and no wobble in the stem.
- Crystal: sapphire should show almost no reflection at an angle; mineral glass shows more.
- Water resistance: treat any claim above splash resistance as unproven unless the case back is properly sealed and the gaskets are new.
- Dial printing: text should be sharp under magnification, with even spacing and no bleeding at the edges.
- Bracelet or strap fit: end links should sit flush against the case with no gaps you can catch a fingernail in.
Quick Answers
Is a 47mm Drive replica the same size as the real one?
No. The genuine Drive family is a dress line with much smaller cases, so a 47mm example is either a different model or a listing error.
Does a bigger case mean a better movement?
No. Case size and movement quality are unrelated. A large case can hold a small movement, which is one reason dial proportions look off in photos.
What should I ask before buying?
Request caliper photos of the diameter and the lug-to-lug measurement, a wrist shot with the wearer's wrist size, and clear pictures of the crown, case back, and clasp.
