The Cortebert 271 watch movement, which was adopted by Longines after acquiring Record, features a micrometer regulator. While it is uncertain if the later variations with 21600A/h were also offered as Record calibers, the Cortebert 271 incorporates several functions, including automatic winding, sweep second hand, day indicator, and a quickset date that can be adjusted by repeated pushing of the crown. This movement was commonly used around 1972.
