A fake Rolex 1908 ref. 52513 stands or falls on three measurements: the 39 mm case, the thickness under 10 mm, and the small-seconds subdial at 6 o'clock. The genuine 1908 is a slim gold dress watch, so a replica that sits tall on the wrist or shows a flat, stamped subdial gives itself away from across a table. Check those three points first, then move to dial printing, crown engraving, and strap hardware.
What the 1908 Ref. 52513 Is Supposed to Be
The 1908 arrived in 2023 as the replacement for the Cellini line, and it is Rolex's return to a pure dress watch. The case is 39 mm in 18k gold, with a thin profile, long curved lugs, and a choice of a domed or fluted bezel supplied in the box. Inside sits caliber 7140, a micro-rotor movement with a 66-hour power reserve and Superlative Chronometer accuracy rated at −2/+2 seconds per day. The dial carries applied indices, a rail-track minute scale, and a small seconds subdial. The strap is alligator leather on a gold deployant clasp. The 52513 reference marks one specific metal and dial pairing within that family, so confirm the exact colorway before you compare anything.
Prerequisites for a Fair Inspection
- A 10x loupe or a macro lens that reaches 10x
- Digital calipers that read to 0.1 mm
- A gram-accurate scale
- Reference photos of the genuine 52513 dial and caseback
- A timegrapher, if the movement is mechanical
- Bright, diffuse light with no colored cast
Inspection Procedure
- Measure the case diameter across the bezel at 9 to 3 and confirm it lands near 39 mm.
- Measure case thickness from the crystal apex to the caseback center and compare it with the genuine figure of roughly 9.5 mm.
- Run a finger along each lug and note whether the curve is continuous or shows a machining step.
- Examine the dial text under the loupe for sharp letterforms and consistent stroke weight on the coronet.
- Study the subdial: genuine examples show fine concentric snailing and a hand with a defined counterweight.
- Inspect the crown for a deep, clean coronet relief and a consistent count of flutes.
- Look through the caseback sapphire at the movement, checking for a micro-rotor, polished bevels, and engraved bridges.
- Check the strap stitching density and the clasp engraving depth, since these are common cost-cutting points.
- Weigh the watch and note the result, keeping in mind that strap material shifts the total.
- Place the watch on a timegrapher and record the rate and amplitude in two positions.
Where Replicas Usually Fail
Subdial and Dial Finishing
This is the hardest detail to copy at a low price. A cheap subdial is stamped and flat, with a printed ring standing in for snailing. Genuine dial printing sits slightly proud of the surface and holds a crisp edge under magnification.
Case Thickness and Profile
Replica cases frequently run 1 to 2 mm thicker than the original because the movement is taller. That extra height changes how the watch sits under a shirt cuff and is the single easiest tell to confirm with calipers.
Movement Finish
A decorative plate with printed bridges will not show a working micro-rotor, and the engraving will lack depth. Look for beveled edges that catch light along a straight line, not a soft blur.
Strap and Clasp Hardware
Stitching spacing, edge paint, and the crispness of the clasp coronet separate a careful build from a rushed one. Check the clasp interior, where finishing standards drop first.
Reading the Result
If the case measures near 39 mm by 9.5 mm, the subdial shows textured finishing, the crown engraving is deep and even, and the movement displays a micro-rotor with polished bevels, the watch is a high-grade replica of the 1908. If two or more of those checks fail, treat it as a lower tier build regardless of how the listing describes it. Record your measurements and photos before you decide, since a single flaw means little without the rest of the data.
