No, and nothing on a photo can show water resistance. The Ringlock System, the helium escape valve and the 3,900 m rating belong to the original; on a rep the valve is a visual detail. What a pressure test does and doesn’t tell you is in [swimming with a rep diver](https://superreps.net/t/rep-diver-swimming-pressure-test-water-resistance-gaskets/101). For comparison, the smaller sister model with the same kind of valve is covered in [Sea-Dweller 126600 QC](https://superreps.net/t/sea-dweller-126600-qc-red-lettering-cyclops-helium-valve/31684).
