The A. Schild 1448 watch movement was jointly developed by Hamilton-Buren, Breitling, and Heuer during the period from 1969 onwards. It features the Dubois-Depraz 8510 module on a modified Buren 1281 base. The movement includes a crown positioned at 9 o'clock, a micro rotor, and a double excenter regulator for the curb pins and stud carrier. In addition, the indirectly driven minute hand allows for a low profile design. The A. Schild 1448 movement functions as an automatic chronograph with 60-second, 30-minute, and 12-hour registers that are cam switched. The movement also incorporates a calendar function that can be adjusted by changing the 21-24 hour range.
