There's something about a man's watch that feels so cool and understated, and it's such a nice way to balance feminine jewelry, like your engagement ring. Cartier's unisex 'Ballon Bleu de Cartier' timepiece takes its name from the floating royal-blue cabochon that's nestled in the bezel. Its classic design foregoes flashy embellishments, instead opting for a sleek 18-karat yellow gold and stainless steel bracelet - the links are curved to ensure it sits comfortably. Wear yours every day with everything from tailoring to floaty dresses.
