PINTIMEFashion Mens Watch Hallow Punk Chronograph Sports Wristwatch Luxury Designer Mens Watch

The minute counter on my watch does not seem to be accurate at all. Is the chronograph just for show? I have 2 of these watches and they both do this

Some have said their watch is not water resistant and fogs up. One of my watches has no gasket under the case back. Could this be the problem?

Which is exactly the warranty? Is it water resistant 50 m. or what?

This or a genuine Richard Mille? I can't decide.
