I have a cartier watch and want to know if it is
Visit an authorized Cartier watch dealer at a high-end jewelry store. Use a jeweler's loupe to inspect the Cartier logo, the dial, the hour, minute and second hands, color, case back and the movement, which is the small electronic or mechanical device that runs the watch. Also examine the bracelet or strap for future comparisons of Cartiers at other dealers. Obtain a copy of the Cartier sales brochure or catalog and read it.
Inspect the movement by asking the seller to remove the case back to view it. It will be engraved with the Cartier name. If the seller balks at the request, don't buy the watch. The seller may have something to hide, according to Spotcounterfeits.co.uk.
Consider the heft of the Cartier if you are considering purchasing a watch from an independent seller. Knockoff Cartiers are considerably lighter than the genuine article because they are made with cheap materials. Examine the Cartier logo to see if it's spelled correctly. Knockoffs usually originate from non-English speaking countries where English is not the primary language and workmanship is poor.
Drop a tiny bit of water on the crystal. Cartiers feature a sapphire glass crystal, in which the water beads on contact. If the water smears, the crystal is a cheap imitation.
Examine the Cartier trademark polished cabochon gemstone on the crown. The stone should be set firmly in the crown but not glued on. Use a jeweler's loupe to look for traces of glue.
Examine the Cartier logo of twin Cs on the case back, dial and strap buckle. The logos should be gracefully produced with no rough stamping.
