Short answer
A fake Rolex 116610 is a counterfeit copy of the Submariner Date reference 116610LN, the 40mm stainless steel dive watch Rolex produced from 2010 to 2020. It is one of the most copied watches in the world because the design is simple, famous, and easy to photograph. Cheap copies are obvious from across a table. Better ones need measurement, close inspection of the dial and bezel, and a watchmaker who can open the case and examine the movement before you can call it with confidence.

How to check a 116610 for authenticity
Gather a jeweler's loupe, a digital caliper, a kitchen scale, and a small flashlight before you start.
- Measure the case with calipers. Genuine width is 40mm at the bezel, and lug width is 20mm. Copies frequently run 40.5mm or wider, or sit noticeably thicker.
- Weigh the watch on a full bracelet. Real 116610LN examples land near 155 to 160 grams. Many replicas come in 20 to 40 grams light because the steel is not 904L.
- Study the rehaut engraving under the loupe. Real engraving is crisp, evenly spaced, and aligned to the dial printing. Fake engraving looks shallow, crowded, or cut at an uneven depth.
- Look for the laser-etched coronet on the crystal at 6 o'clock. Tilt the watch toward a light source. Copies often skip it or etch a version that is too large and too dark.
- Inspect the bezel insert. Genuine platinum-filled numerals sit flush to the ceramic and stay bright. Paint-filled numerals on fakes sit slightly raised, chip at the edges, or turn yellow.
- Charge the lume with the flashlight and check the color. The 116610 glows blue. Green lume on this reference is a red flag.
- Confirm the caseback is plain. A 116610 with a display caseback is not genuine, since Rolex never sold one that way.
- Have a watchmaker open the case. Caliber 3135 shows specific finishing, a free-sprung balance with Microstella nuts, and 31 jewels. This is the only step that settles a close call.
- Verify the serial and any service history through a Rolex service center or authorized dealer before money changes hands.
Legal position in the US
Trafficking in counterfeit watches is a federal offense under 18 U.S.C. § 2320, and U.S. Customs and Border Protection seizes counterfeit goods at ports of entry. A watch sold as a 1:1 replica or super clone is still a counterfeit under the law. It carries no Rolex warranty, no parts support, and almost no resale value. If a used 116610 is priced far under market or the seller pushes you to move fast, stop and pay for an independent inspection. Pre-purchase authentication costs a fraction of a counterfeit.
