Had "warranty" explained to me by very reputable jeweler in my home town.  It is true that buying from Amazon does not entitle you to Tag's warranty, but here is the reason.  Tag allows a certain number of distributors world wide, and basically, the U.S. is one market.  Obviously, Amazon has gone outside of that market and purchased elsewhere, so U.S. dealers won't recognize warranty.  However, as my jeweler went on to explain, a Tag is an excellent watch, and the stem breaking (as other reviewer stated) would not have been covered by Tag anyway, as that was owner error, not manufacturing.  Tag's warranty is very similar to Amazon's and based on reliability of the product and the price difference, I felt safe buying from Amazon.  Have had watch for several months now, and love, love, love it!  Also, my jeweler (as any good jeweler should be able to do)  can service my watch should the need arise, so you don't have to send it off unless it is something very major.  The price of these watches increases every few months, so don't wait.  It has already gone up $300. since I purchased mine.
