Caliber 866AA was introduced in 2020 as an updated version of caliber 866 (/1). This new version offers a 70 hours power reserve which is achieved through optimizing the performance, notably through a new barrel design, new forms of lubrication, a new adjustment of the second hand, and a the silicon escapement which significantly reduces friction.

5 other watches in the library run the Jaeger Lecoultre 866AA.
