The Tissot 791 watch movement is a hunter calibre with the option of incorporating a Breguet hairspring. It features varying bridge shapes and is speculated to possibly include a left-handed ratchet-wheel screw. The differences between the Unitas 32 and Tissot 791 are not clearly defined and are likely just catalog designations for variations in bridge shapes. The movement offers functions such as stem winding and setting, as well as a sub-second display.
