Short answer
The 126518LN is a real Rolex reference. It is a 40 mm Daytona in 18k yellow gold with a black Cerachrom bezel, calibre 4131, and an Oysterflex strap. Replicas of this reference come from China. They copy the shape. They do not copy the gold, the movement, or the finishing. Street prices run from about $200 to about $1,000. No replica is a Daytona.

What replicas of this reference tend to be
- Case: steel with gold plating or PVD, not solid 18k gold. Plating wears at the lugs and the caseback edge.
- Movement: an Asian 4130 clone or a 7750-derived chronograph. Some sellers list a Dandong 4130. The genuine 4131 has a different bridge shape and balance assembly.
- Bezel: ceramic or coated steel. Numerals are printed or laser etched. They are not gold-filled by PVD.
- Strap: silicone or rubber. The genuine Oysterflex has titanium blades molded inside the rubber.
- Dial: printed indices with lume that differs in color and height from the genuine plots.
Checks that settle it
- Weigh the watch. A solid gold case weighs more than a plated steel case of the same size. Published weights vary by strap size. Weigh against a known example.
- Read the rehaut. The engraved "ROLEX ROLEX" ring and the serial at 6 o'clock should be sharp and even.
- Run the chronograph. Start, stop, reset. A 7750-based copy has a different pusher feel and the chronograph seconds hand can stutter.
- Check the clasp. Gold Oysterlock clasps carry a code stamp. Copies often use the wrong code for the reference.
- Look at the caseback. It is solid, so a movement check needs a watchmaker with the case opened.
- Ignore the box and papers. Copies ship with copied paperwork. Documents alone prove nothing.
Price and market
Rolex sets retail by region. Secondary prices for the 126518LN sit near or above retail in most markets. Replica listings ask a few hundred dollars. A price far under market is the clearest signal of a copy or a scam.
Legal position in the US
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320. CBP seizes counterfeit watches at ports of entry. Selling a replica as genuine is fraud. Personal possession and resale carry different exposure.
