Answer first: a counterfeit Speedmaster Dark Side of the Moon fails on the case before it fails anywhere else. The genuine watch is a 44.25 mm zirconium-oxide ceramic case, brushed and polished before sintering, so the contrast between matte and gloss surfaces is cut into the material itself. Fakes mold the case, then paint or plate the finish on top. Look at the case first, the movement last, and you will reach a verdict in under two minutes.
What you need before you start
- A bright, raking light source (a phone flashlight works)
- A loupe or a phone camera with macro mode
- A kitchen scale that reads in grams
- The reference photos of the exact model year you are checking
The inspection procedure
- Weigh the watch on the strap. Genuine ceramic cased Speedmasters sit well under the weight of a steel chronograph of the same diameter. A counterfeit that feels heavy in the hand like steel is a fake with a coated metal case.
- Run a fingernail across the case flank where the brushed surface meets the polished facet. Genuine ceramic carries a sharp, continuous transition. Fakes show a rounded, soft edge from plating buildup.
- Tip the case into raking light and check the bezel for a tachymeter scale that looks printed or screen-printed on the surface. On the real watch the scale is integrated into the ceramic, with no ink sitting above the material.
- Inspect the dial with the loupe. The indices and the running track are laser-ablated into the ceramic dial, sitting in shallow recesses. Painted or pad-printed markers sit flat and show a raised edge under magnification.
- Count the subdials. Calibre 9300 uses a two-register layout: small seconds at 9 o'clock and a combined hour and minute chronograph counter at 3. A counterfeit with three subdials is not replicating this movement at all.
- Confirm there is no date window. The Dark Side of the Moon has no date aperture, and any fake with one at 3 or 6 is built on a generic chronograph base.
- Look at the hands. They should be white gold with clean, crisp edges and an even lume fill. Stamped sheet-metal hands with fuzzy edges and uneven lume are the standard fake tell.
- Turn the watch over and read the caseback. Engraving on genuine ceramic is laser-cut with a uniform depth and no burrs. Etched or pad-printed lettering that wipes off with a thumbnail is counterfeit.
- Check the caseback crystal and the serial engraving around the rim. Fakes often reuse one serial number across a whole production run, so search the number before you buy.
- Wind and run the chronograph. The pushers should start, stop, and reset with a firm, dry click. A mushy pusher with a spongy return points to a modular quartz or low-grade automatic inside.
Red flags that end the inspection
Stop at any of these: the strap buckle is stamped steel rather than ceramic or titanium; the caseback text is a decal; the chronograph hand snaps back instead of sweeping home; the seller cannot show a service history or an original box with matching reference numbers. A ceramic case that shows a scratch deep enough to catch a fingernail is not ceramic, and ceramic on this model does not scratch.

Where the fakes still fall short
Case geometry and movement finishing remain the two gaps. Factories can copy the silhouette in renders, but sintering a ceramic case with correct facet lines is expensive, and no counterfeit reproduces the column-wheel chronograph architecture under a display back. Judge the watch with the loupe on the case edges and the movement bridge finishing, and the answer is clear.
