Hi, I've received a must de cartier watch...and i'm not sure if it's authentic or not. I took some pics but they're really blurry. thought maybe you guys can help me out. on the back it says: Cartier SWISS MADE ** ARGENT** (THE * MEANS SOME SORT OF STAMP THAT I CAN'T MAKE OUT) PLAQUE OR G 20 M 1810 1 007984 <~~~~~(IN BLACK, SLIGHTLY DIFFERENT FONT) it's got 4 sets of 2 screws all around the back on one strap it says cartier paris, the other says made in france on the gold-hardware closure it says: SWISS MADE Must de cartier the front is a little more clear in the pics, and it says SWISS on the bottom. Blue hand-dials.. any idea?
