I have read the warranty card has to be stamped and completely filled out by the AD for the warranty to be valid.
If I received a blank warranty card with a new Tissot, should I go back and have the AD to complete it? Is the watch receipt from the AD sufficient if you need service under warranty?
There seems to be a website where one can register your Tissot watch. If you complete the online registration, does this suffice for future warranty purposes?
