Jaeger-LeCoultre Master Ultra Thin vs Cartier Ballon Bleu White Gold Medium

The Cartier Ballon Bleu is the more distinctive watch: its rounded case, domed crystal and Roman numerals are instantly recognizable, and the white gold case with a leather strap reads as jewelry in a way the JLC does not. The Jaeger-LeCoultre Master Ultra Thin is the more restrained and versatile choice, with a slimmer profile, a date window and a rose gold case that suits dress wear. Both use automatic movements with roughly 38 hours of power reserve and sapphire crystals, so the choice comes down to style and how much water resistance you want.

• Choose the Jaeger-LeCoultre Master Ultra Thin if you want a slim, understated dress watch with a date and a warmer rose gold case.
• Choose the Cartier Ballon Bleu if you want a recognizable design with Roman numerals and a white gold case that stands out on the wrist.
