Quick answer
The Rolex Deepsea reference 136660 is a 44 mm dive watch rated to 3,900 m (12,800 ft). It runs the cal. 3235 movement with a 70 hour power reserve and Superlative Chronometer certification of -2/+2 seconds per day. A fake version copies the look, not the engineering. No replica of the 136660 has a tested 3,900 m rating. Most replicas use a 316L steel case, an Asian automatic movement, and gaskets that fail a pressure test at depth. Selling or importing counterfeit watches is illegal in the United States.

What sellers mean by first copy
First copy, 1:1, and super clone are seller labels. None has a fixed definition or a grading body. The same watch can appear under all three names on different listings. Sellers sort stock by factory name and by the movement inside. Price tiers track the movement, the steel grade, and the finish, not the water resistance.
Common differences on replica 136660 models
- Cyclops magnification: genuine is 2.5x. Copies run 1.5x to 2x and the date font sits off center.
- Bezel action: the genuine bezel has 120 clicks and no play. Copies show 60 to 90 clicks and rock in the seat.
- Lume: Chromalight burns blue for hours. Replica lume fades in 30 to 60 minutes.
- Movement: the genuine cal. 3235 has a free-sprung balance with Microstella screws and 31 jewels. Asian clones use a regulator arm and a different jewel count.
- Engraving: model number 136660 sits between the lugs, and the serial sits on the rehaut at 6 o'clock. Copies misalign both.
- Weight: replicas built on 316L steel weigh less than the genuine watch on a full Oyster bracelet.
Price tiers
Replica Deepsea models sell across a wide range. Quartz builds sit at the bottom. Asian 2824 clones and decorated 3235 clones sit at the top. Exact figures change by seller and by year, so ask for the movement name in writing. No replica factory publishes a pressure test result. Depth figures on listing pages are copied from Rolex specifications.
US law on counterfeits
18 U.S.C. 2320 covers trafficking in counterfeit goods and carries prison terms and fines. US Customs and Border Protection can seize counterfeit shipments at the border. A personal purchase does not create a right to import the item. Rolex holds trademark rights in the name, the crown logo, and dial elements.
Questions to ask a seller
- What movement is in the watch, and who makes it?
- What steel grade is the case, 316L or 904L?
- What gasket material seals the case back and crown?
- What is the return policy, and is it in writing?
If a seller cannot name the movement, the listing is a stock category page. If a seller claims 3,900 m of water resistance, that figure came from Rolex and was not tested on the replica.
