Discover Jaeger-LeCoultre's precision with the Reverso (ref. Q39434E1), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in white gold and measuring 31 mm in diameter, with a thickness of 13.63 mm, defined by a rectangular silhouette. The caseback is double dial, and the crystal is sapphire, delivering water resistance to 3000 meters.
