First things first, and this is important: is your replica actually *designed* to even *be* waterproof? Like, did it *look* like it’s a dive watch when you bought it? ‘Cause if it’s some fancy dress watch trying to masquerade as a Submariner, you’re already fighting a losing battle. Think about it – a watch designed to resist water will have tighter seals and a screwed-down crown. If it’s just a snap-on back with some decorative screws, well… good luck.
Now, some folks online are selling “waterproofing services” for replica watches. Hmm. Sounds kinda sketchy, doesn’t it? Like, what exactly are they DOING for the money? Slapping some silicone grease on the seals? Probably. Are they actually pressure testing it to 300 meters like those “Swiss made” Rolex replica ads claim? Highly doubtful. Honestly, it’s a gamble. You might get someone who knows their stuff, or you might just get ripped off. Buyer beware, ya know?
From what I’ve seen, the main thing they (allegedly) do is replace the gaskets. The rubber rings that seal the caseback, crown, and crystal. Gaskets are your watch’s first line of defense against H2O. Problem is, even if you replace them, those replica cases often aren’t made to the same tight tolerances as a genuine watch. So, you might have gaps, you might have imperfections… it’s a crapshoot.
Look, if you’re serious about wanting a waterproof watch, honestly, just buy a real one. I know, I know, that’s not what you wanted to hear. But think about it – you’re already spending money on a fake, why not save up a bit more and get something that’s actually going to do what it’s supposed to? A good Seiko diver is way cheaper than a Rolex and will actually keep water out, guaranteed.
