The Felsa 4468 watch movement was developed in collaboration with Hamilton-Buren and Heuer between 1969 and the present. It features a modified Buren 1281 base with a Dubois-Depraz 8510 module. Notable technical aspects include a crown positioned at 9 o'clock, a micro rotor, and a double excenter regulator for curb pins and stud carrier. The movement allows for a low profile with its indirectly driven minute hand. Functionally, it offers an automatic chronograph with 60-second, 30-minute, and 12-hour subdials. Additionally, it supports a date complication set by changing the 21-24 hours and a 24-hour GMT indication.
