The A. Schild 1775 watch movement is the result of a joint development between Hamilton-Buren, Breitling, and Heuer during the period of 1969 onwards. It incorporates the Dubois-Depraz 8510 module integrated into a modified Buren 1281 movement. The crown is positioned at 9 o'clock, and the movement features a micro rotor which allows for a low profile design. Additionally, it includes a 60-second and 30-minute automatic chronograph function with cam switching, a sub second display at 10 o'clock, and a date function that can be set by changing the 21-24 hour indicator.
