Well you take the sucker off.
Do you even know what it costs to get a watch water proofed?
I'll let you know. Mrs has a lifetime free battery replacement for her watch.
She doesn't even wear it swimming or in the shower. But for some reason she always sends it away for 3 weeks for waterproofing. $50
I bet your watch isn't waterproof. The guy in the mall simply can't do it.
