Introduced in 2015 in the Geophysic collection, caliber 770 features dead-beat (jumping) seconds and date function. Features the Gyrolab balance wheel - an atypical non-circular configuration that reduces air resistance for improved precision. This true seconds mechanism causes the hand to jump every second, a remarkable feat for a mechanical movement.
