I just wondered if anyone could give me an insight on the water resistance of Chinese Homage watches, especially Parnis/Bliger dive watches. I am fully aware that the guarantee is 30m, which in realty is no more than splash proof, but I just don't understand why. It's incredibly easy to make a watch waterproof to about 200m, have a seal on the crown, and a screw back with a seal, and it's pretty much done. My Bliger divers watch has a screw crown, and a screw back with a seal, so I really can't understand why it has no waterproof rating as such. I recently read a thread on another site (can't remember which one) from a guy who dived for years with his Rolex homage with no WR guarantee, and it had never leaked. That said, I wouldn't want to risk it myself. I am fully aware that having them officially tested and certified would add far to much to the cost, however there are plenty of 200m watches that are not certified, such as Invicta, which are fine in the water.So, can anyone give me an insight, or indeed any experiences of their own ?
