Hey all, So I just purchased a Tudor black bay from a grey market dealer. The watch came in perfect condition with all Tudor stickers still on it, so it was brand new. Since I got it it hasn’t lost a second. But, since I didn’t buy it from an AD I’m a little worried about the water resistance. Since it came brand new, should I just assume the water resistance was tested by Tudor and is functional? The screw down crown is functioning just fine. Not sure if this is a dumb question but it’s been worrying me. Thanks!
