Jaeger-LeCoultre 772

Caliber 772 is an automatic movement introduced by Jaeger-LeCoultre in 2015, first featured in the Geophysic collection. It features deadbeat seconds and world time complications, with a true seconds system that advances the seconds hand in discrete steps each second. The movement incorporates the Gyrolab® balance wheel, a non-circular design developed to minimize air resistance and improve precision. This caliber remains in production and is used in Geophysic models.
