Answer
Rolex reference 126618 is the Submariner Date in 41 mm yellow gold. Rolex released it in 2020 with the rest of the 41 mm Submariner line. A "replica 126618" is a counterfeit watch built by a third party. It copies the case, dial, and bracelet shape. It holds no Rolex movement and no 18k gold case. In the US, selling or importing that watch is illegal under 18 U.S.C. § 2320 and the Lanham Act.
What reference 126618 is
- Model: Submariner Date, 41 mm.
- Case: 18k yellow gold, water resistance rated to 300 m.
- Movement: Rolex calibre 3235, automatic.
- Power reserve: about 70 hours.
- Rate: -2/+2 seconds per day, the Superlative Chronometer standard.
- Bracelet: yellow gold Oyster with Glidelock clasp.
- Dial variants: 126618LN (black), 126618LB (blue).
US list price sits in the low $40,000s. Rolex sets new prices each year, so confirm the current number.
What replica versions contain
Replica sellers sort stock by grade, and price tracks grade.
- Low grade: $50 to $150. Steel case with gold tone plating. Quartz or basic automatic movement. Stamped case back.
- Mid grade: $200 to $500. Plated steel. Chinese automatic movement, often a copy of an older Rolex calibre. Sharper dial print.
- High grade, sold as "1:1" or "super clone": $500 to $1,200. Steel case with thicker gold plating. A movement that copies the 3235 layout, sold under labels such as VR3235 or VS3235.
No grade puts a solid 18k gold case on the wrist at these prices. Gold costs money. 18k gold has a density near 15.6 g/cm3. Steel sits near 7.9 g/cm3. A gold watch of one size weighs about twice a plated steel copy of the same size. Weight is the fastest check on a 126618.
Gold plating
Plated replicas carry a gold layer measured in microns. Sellers cite 3 to 5 microns. Wear on the clasp, crown, and case edges exposes the steel under the plating. Solid gold does not change color at those points. A scratch on solid 18k gold stays gold.
The "Swiss made" claim
Swiss law sets the test for the "Swiss made" label. Since 2017, at least 60 percent of the manufacturing costs of an industrial product must occur in Switzerland. Replica watches do not meet that test. A watch sold as a "Swiss replica" is not made in Switzerland. The dial marking in that case is a false statement of origin.
US law
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320. A first offense carries up to 10 years in prison. Fines reach $2,000,000 for an individual and $5,000,000 for a company. Trademark owners can also sue. Under 15 U.S.C. § 1117(c), statutory damages for a willful counterfeit mark reach $2,000,000 per mark per type of good.
US Customs and Border Protection seizes counterfeit goods at the border. CBP states that a single counterfeit item for personal use can be seized and destroyed. The buyer can face civil penalties.
Points that are not known
Replica sellers do not publish movement origin, plating thickness, or case metal testing. Claims on those points come from the seller and cannot be checked before purchase. There is no independent standard for replica grades. The terms "1:1" and "super clone" have no fixed definition.
