The Cortebert 618 watch movement, along with its variants such as 6BA and 6BE, is a manual wind movement that was used during the period from 1949 to 1952. It is considered to be quite equivalent to the Aurore-Villeret 120 and FHF 120 calibers, with some design details unique to the Bulova calibers.
