I have had my Cartier Tank Francaise watch for 3 years.It stopped working.I was told by my jeweler that they need TUNEUPS(!!!) every couple of years..and GUESS WHAT???IT ONLY COSTS 400 DOLLARS!Yep! You heard me..Actually 428.00 total..WHAT A RIPOFF..BET thats why they dont tell ya that when you buy one..I love my watch but GEESH! Thats a lot of maintenance for an EXPENSIVE WATCH!???Isnt it? OK..Ive vented.I got my watch back in time for my Paris trip today..BUT I wasnt too happy about the maintenance thing at all!
