Short answer
"Copy drive 41mm" is a search phrase with three parts. "Copy" means replica. "Drive" points to the movement that turns the hands. "41mm" is the case diameter. Buyers use the phrase for replica Rolex watches that copy a 41mm case and run on an automatic movement. Four current Rolex lines use a 41mm case, so the phrase alone does not name one model.
Rolex models with a 41mm case
- Submariner Date 126610LN and 126610LV: 41mm case, launched 2020.
- Submariner No Date 124060: 41mm case, launched 2020.
- Datejust 41, references 126300 and 126334: 41mm case, launched 2017.
- Oyster Perpetual 41, reference 124300: 41mm case, launched 2020.
Earlier Submariner models used a 40mm case. The move to 41mm also changed the Submariner lug width to 21mm. A seller who writes "copy drive 41mm" without a reference number is not naming a model.
Fake Drive 41mm for Sale: What to Check Before You Buy
What "drive" refers to
Rolex fits the 41mm Submariner with calibre 3230 or 3235. The Datejust 41 uses calibre 3235. The Oyster Perpetual 41 uses calibre 3230. Power reserve on these calibres is about 70 hours. Frequency is 28,800 beats per hour.
Replica sellers use "drive" for the movement inside the case. Common labels are clone movement, Asian ETA, and Miyota. A clone copies the layout of the Rolex calibre. An ETA or Miyota unit is a third-party movement with a different design. No public spec sheet from a replica factory exists. Claims about which movement sits in one specific replica cannot be checked.
Measurements buyers check
- Case diameter: 41mm across, measured without the crown.
- Lug width: 21mm on the Submariner 41 line. Figures for the Datejust 41 differ between sources.
- Thickness: published figures sit near 12.4mm for the Submariner 126610 and near 11.7mm for the Datejust 41.
- Weight: a steel Submariner 41 with a full bracelet is listed near 155g. Replica weights run lower.
Legal status in the United States
Counterfeit watches are illegal to sell and to import. 18 U.S.C. 2320 sets a maximum of 10 years in prison for trafficking in counterfeit goods. First-offense fines reach $2,000,000 for a person and $5,000,000 for a corporation. 19 U.S.C. 1526 covers importation of goods that carry a counterfeit mark. U.S. Customs and Border Protection seizes counterfeit watches at ports of entry. A personal-use purchase is charged at the same level as a sale, but the item can still be seized and destroyed.
