Query: 5 Year Warranty

You can go online to InvictaWatch.com and register your watch and extend a 1 year warranty to the 5 year platinum warranty for free. I did it the other day and the process takes less than 10 minutes. It's a lot better than sending the warranty off in the mail and waiting for a reply in about 6 weeks. --And yes, this is easily the best watch I've owned for less than $100.P.S. You'll need to refer to your Amazon.com billing slip (order number and item number) and the warranty application's number code that comes with the watch to qualify for the free 5 year platinum warranty. --Once all the information is entered and accepted your watch is covered. And according to Amazon.com you have a 7 day window from the time you receive the watch to the time you register your watch to qualify for the free platinum warranty. --Other wise you'll have to pay for it.
