The Ulysse Nardin 8 watch movement, also known as the hunter calibre, was utilized by Alpina and Novice brands in approximately 1925. Notable features of this movement include options such as a bimetallic screw balance, Breguet hairspring, and Reed's regulator. Additionally, different click springs are present, and it is highly likely that the movement incorporates a left-handed ratchet-wheel screw. Currently, details regarding the distinctions between the hunter 273 and 274 remain unknown. The movement offers functions like stem winding and setting, as well as a subsecond display.
