Elegance, sophistication, and class: these are just some of the descriptions that come to mind when Cartier is mentioned. As one of the oldest jewelers in the world, Cartier is an expert when it comes to catering to the whims of celebrities, billionaire businessmen, and royalty. The highly diverse line from this company is also testament to its versatility. And unlike many innovative luxury watchmakers, Cartier actually became popular for their light, airy jewelry before it expanded into watch making. Cartier is only becoming stronger in the industry as it introduces more luxurious, appealing, and cutting-edge watches.
