The ETA 2380 watch movement is a joint development between Hamilton-Buren, Breitling, and Heuer. It features a module Dubois-Depraz 8510 on a modified Buren 1281 base. The movement incorporates a crown located at 9 o'clock position and utilizes a micro rotor. It also incorporates a double excenter regulator for curb pins and stud carrier. The indirectly driven minute function allows for a low profile design. The ETA 2380 movement offers various functions, including an automatic chronograph with 60-second, 30-minute, and 12-hour counters that are cam switched. It also features a date function, which is set by changing the 21-24 hour time display.
