i've been interested in buying a cartier watch (the small tank thats $3300) and i found a local jeweler who is willing to do 21% off......Saks would only do 10% or 15% if i open some kind of account with them (not the regular Saks card). the jeweler is reputable and i looked on their website and it says they ARE authorized dealers of cartier. i'm a little concerned about it being a grey market watch.....i guess because i'm not completely sure of what it is. if the watch comes with the regular warranty (how long is cartier's warranty anyway?) does that mean that its pretty much NOT a grey market watch? thanks for any advice you can offer!
