A replica Rolex with a green dial or green bezel holds water the same way any watch does: case seals, gaskets, crown, case back, and crystal. Dial color has no effect on depth rating. A printed 300 m on the case back is a claim, not a test. Only a pressure test proves the watch is sealed.
Which green Rolex models this covers
Rolex shipped three green Submariner references. 16610LV (2003): black dial, green aluminum bezel, 300 m. 116610LV (2010): green dial, green Cerachrom bezel, 300 m. 126610LV (2020): black dial, green Cerachrom bezel, 300 m. Replica makers copy all three. The green dial is the part that varies most. Originals use a lacquer coat over a sunburst finish. Replicas range from flat paint to a close match.

Water resistance numbers
- 30 m (3 atm): splashes and rain. Not for swimming.
- 50 m (5 atm): short swims.
- 100 m (10 atm): swimming, snorkeling.
- 200 m (20 atm): recreational diving.
- 300 m (30 atm): scuba, matching a Submariner rating.
ISO 22810:2010 sets test methods for water-resistant watches. ISO 6425:2018 covers divers' watches. That standard requires a 100 m minimum rating plus tests for thermal shock, salt water, and pressure.
Where replicas leak
Four spots fail first. Crown gaskets dry out or sit missing. Case back O-rings rest in a shallow groove or get pinched. Crystal gaskets lose compression. Pusher seals on chronographs wear. A replica marked 300 m may pass at 3 bar and fail at 10 bar. Most watchmakers test at 3 to 6 bar for daily wear and charge 20 to 50 dollars.
Green underwater: lume, not the dial
Rolex Chromalight emits blue light. Older Super-LumiNova emits green light. Photos of a green glow in dark water show the lume, not the dial or bezel.
Salt water and damage
Salt water attacks 316L stainless steel less than brass. Replica cases with plated brass corrode. Water inside a case causes rust on the movement within days. Signs include fog under the crystal, a stopped seconds hand, and discolored dial edges. A service costs more than the replica.
Legal note
In the US, trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320. Customs and Border Protection seizes counterfeit watches at import.
