Cartier’s Two-Tone Ballon Bleu Watch 36mm is a unisex Swiss-made timepiece with automatic self-winding movement! Introduced in 2007, this watch is made of stainless steel and 18K yellow gold, a silvered guilloché dial, black Roman numeral hour markers, blue-steel hands, and a sapphire crystal. In very good condition, it comes with a box and has some scratches on the metal. The bracelet has a hidden butterfly clasp, which some consider to be superior to a deployment clasp because the latter might require professional fitting!
