I haven't, but it isn't unknown for a watch battery to leak and it isn't unknown for the breath of the person changing a battery to create condensation that gets trapped inside. Dust and dirt too can gain access while the back is removed.
Or, it can be just coincidence.

It is here

Please search eBay with key word " TB1098 Strap "

You may go to http://www.tommybahama.com/TBG/GeneralContent/CustomerService.jsp#warranty_repair_watches
and download the manual or contact the company via email.

Not for the feint hearted. Probably comes out the top instead of the back, take it to a watchmaker. (not a store clerk or sales person)

MY suggestion would be to take to a local jeweler/watchmaker to see if its the battery. They should have a battery tester to check to see if that is the case. Probably is.
If its NOT the battery, it seems like its defective and I would start inquiring where they bought the watch. I know. Tricky, because it was a gift, but well, they would want to know too
Good luck and let me know if that helps!!! J

Go to http://www.genevawatchgroup.com/ and on the menu on the right there is "customer service", click on this and scroll down until you reach the instructions for your watch.
