Short answer

The Rolex Cosmograph Daytona reference 126509 is a 40 mm chronograph in 18k white gold. Rolex introduced it in March 2023 as the replacement for the 116509. A replica of the 126509 is an unlicensed copy. Rolex does not make it, sell it, or service it. In the United States, selling or importing that copy breaks federal trademark and customs law.

A replica does not share the 126509 movement, gold, or finish. The genuine case is 18k white gold. Copies use steel, brass, or plated metal.

What "first copy" and similar terms mean

Terms such as first copy, super clone, 1:1, and AAA come from sellers. No watch body defines them. No grading standard exists. Two watches sold under the same term can differ in movement, case alloy, and finish. Photos on seller pages are often of a genuine watch.

United States law

  • 15 U.S.C. 1114 and 1125 (Lanham Act): a trademark owner can sue sellers and distributors of counterfeits.
  • 18 U.S.C. 2320: trafficking in counterfeit goods. A first offense carries up to 10 years in prison and a $2 million fine for an individual. A second offense carries up to 20 years.
  • 19 U.S.C. 1526: importation of counterfeit merchandise is prohibited. U.S. Customs and Border Protection can seize and destroy shipments.

The trafficking statute targets sellers, distributors, and importers. Buying one watch for personal use is not the same charge in most cases. The shipment can still be seized, and the money is gone.

Risks reported by buyers

  • No warranty and no service from Rolex or an authorized dealer.
  • Metal content unknown. White gold copies are steel or plated.
  • Water resistance untested. Gaskets can fail and rust the movement.
  • Payment by wire or crypto has no chargeback.
  • Resale value near zero. Dealers and pawn shops refuse counterfeits.
  • Seller sites often carry card skimmers and malware.

What Rolex service centers do

Rolex service centers and authorized dealers do not service or authenticate counterfeit watches. A watch sent in for service is returned with the work refused and the serial number recorded. A counterfeit cannot be repaired with Rolex parts because Rolex does not sell parts to the public.

Checks on a 126509

Rolex does not publish a public serial database. Buyers check three things: purchase from an authorized dealer, original papers and box with a matching serial, and a movement inspection by a watchmaker. The calibre 4131 has 72 hours of power reserve, a blue Parachrom hairspring, and Rolex Cotes de Geneve finishing. Copies do not match all three.

Retail price for the 126509 is set by Rolex and changes. Rolex does not publish a price for this reference on its public site. An authorized dealer quotes the current figure. Secondary market prices for white gold Daytonas have run above retail in some years.
