The Jaeger Lecoultre 880 watch movement was produced from 1968 to 1973, with a total of 370,000 units manufactured during this period. Unlike traditional manual-wind calibres, the automatic gear is integrated directly into the movement. This design allows for a rugged rotor bearing, while still maintaining a low profile. The movement features an indirect drive for the minute and second hands, enabling a centralized space for the rotor. Additionally, the Jaeger Lecoultre 880 boasts various functionalities such as automatic winding, quickset date, a hack feature, and a sweep second hand. It is worth noting that the movement incorporates a calendar function.
