The A. Schild 1249 watch movement is a result of a joint development between Hamilton-Buren, Breitling, and Heuer during the period 1969 onwards. It features a modified Buren 1281 movement with a Dubois-Depraz 8510 module. The movement includes a crown positioned at 9 o'clock, a micro rotor, and a double excenter regulator for curb pins and stud carriers. The indirectly driven minute hand allows for a low profile design. In terms of functions, it offers manual winding and a sub-second display. The A. Schild 1249 movement was used in watches circa 1930.
