Short answer
A genuine Rolex Yacht-Master 40 (ref. 126622) has a 40 mm Oystersteel case, a 950 platinum bezel, a calibre 3235 movement with a 70-hour power reserve, and a 100 m water resistance rating. A fake copies the outline, then swaps parts: 316L steel in place of 904L Oystersteel, a steel or tungsten bezel insert in place of platinum, and an Asian clone movement in place of the 3235. The case shape matches. The bezel metal, dial print, date font, and movement do not.
Yacht-Master 40 vs Submariner Date 41
The same search term often points to this second comparison. Both models use the calibre 3235 and a 70-hour power reserve. They split on the bezel and the depth rating.
Top Pick: Best Fake Rolex Yacht-Master 40 Review

- Yacht-Master 40 uses an Oysterlock clasp with a 5 mm Easylink extension. The Submariner Date 41 adds the Glidelock extension system.
Bezel and case metal
Rolex stamps the Yacht-Master 40 bezel in 950 platinum and finishes it with a sandblasted surface and polished raised numerals. Platinum has a grey tone. It holds a matte look and resists scratches. Replicas use 316L steel with a platinum-color coating, or a tungsten insert that adds weight. A magnet test does not settle the question. Tungsten alloys react in some cases. Platinum does not react at all.

Genuine cases use 904L steel, which Rolex calls Oystersteel. The alloy carries more molybdenum and nickel than 316L. Both take a polish. 904L holds up better against chlorides.

Dial, crystal, and date
Genuine dials use a sunburst finish, 18k white gold marker surrounds, and Chromalight lume that glows blue. The Cyclops lens magnifies the date 2.5 times. Date wheels sit centered in the window with a sharp serif on the numeral 1. Replicas print markers on brass, and the lume glows green or dims after 30 minutes. Cyclops magnification on replicas lands near 2 times, which shifts the date off center. Dial text on replicas can show wrong spacing between "YACHT-MASTER" and "SUPERLATIVE CHRONOMETER".
Movement
Calibre 3235 runs at 28,800 vibrations per hour and holds 70 hours of power reserve. It uses the Chronergy escapement, a nickel-phosphorus escape wheel, and Paraflex shock absorbers. Replicas carry an Asian 2824 clone at 28,800 vph with a 38-hour reserve, or an SA3135 or VR3135 with a 40-hour reserve. Beat rate matches. Power reserve, rotor noise, winding feel, and finishing do not.
Bracelet and clasp
The Oyster bracelet on the genuine watch uses solid 904L links, a screw-bar system, and an Oysterlock clasp with a 5 mm Easylink extension. Replica bracelets use 316L links, stamped clasps, and pins that back out. End links on replicas sit high against the lugs on some batches.
Water resistance
Rolex rates the Yacht-Master 40 at 100 m. Replica case backs and gaskets vary by factory and batch. No third-party test data backs the claimed rating. Do not swim in one.

Checks
- Check the bezel sheen. Platinum looks dull grey. Coated steel shows a bright ring under light.
- Look at the date. A genuine Cyclops gives 2.5x with no edge distortion.
- Check the lume after 30 minutes. Blue points to Chromalight.
- Wind the crown. The 3235 winds with light resistance and returns a 70-hour reserve.
- Read the clasp code and case back engravings. Replica stamps show wrong fonts and shallow cuts.
