Quick answer
"Replica Rolex Datejust 126300" is a search phrase for counterfeit copies of a real Rolex watch. The genuine reference 126300 is the Datejust 41 in Oystersteel with a smooth bezel. Rolex does not make a replica line. Any watch sold under that phrase is a counterfeit, and U.S. law bans importing, selling, or trafficking in it.
What the genuine 126300 is
Rolex launched the Datejust 41 in 2017. Reference 126300 replaced the Datejust II reference 116300. It is the steel model with a domed, polished bezel. The fluted-bezel Datejust 41 is reference 126334, which uses a white gold bezel.

Rolex U.S. list price for the 126300 sat in the high four figures in recent years. Prices change. Check Rolex or an authorized dealer for the current figure.
What "1:1 Swiss super clone" means
These labels appear in counterfeit listings. None has a standard definition, an inspection body, or a published tolerance. Counterfeit watches are made in unlicensed factories, and the largest production base is in China. A counterfeit stamped "Swiss made" carries a false statement of origin, since Rolex did not make it and Swiss law does not cover it.
Legal status in the United States
Trafficking in counterfeit goods falls under 18 U.S.C. 2320. A first offense carries up to 10 years in prison. The Lanham Act allows statutory damages up to $2,000,000 per counterfeit mark per type of goods when the use is willful. U.S. Customs and Border Protection can seize and destroy counterfeit shipments. The personal exemption for bringing goods home does not cover counterfeit trademarked items.
Why the specs do not hold
A counterfeit does not contain a Caliber 3235. No independent lab tests a fake to -2/+2 seconds per day. There is no parts network, no service center, and no warranty that any manufacturer will honor. Resale value is close to zero, and many watchmakers decline to open a counterfeit case.
Verification
Rolex does not run a public serial lookup for buyers. A Rolex Service Center or an authorized dealer can inspect a watch and confirm the reference. A receipt from an authorized dealer, a matching warranty card, and a service history are the records that carry weight.
