There are many jewelers in the Los Angeles jewelry district in downtown Los Angeles who sell brand name watches such as Cartier, Tiffany, Patek Philippe, etc. at 25% to 30% off of retail prices that one can find at the local Cartier store or a Cartier authorized dealer in the mall for example. Has anyone on this board bought a brand name watch from a discound jeweler in a jewelry district? Are these watch dealers legitimate? Please advise!
