The Fontainemelon 72-2N is a hunter calibre mechanical watch movement utilized from approximately 1945. It features functions such as stem winding and setting, as well as a small seconds subdial. The movement may incorporate an optional Breguet hairspring, and there may be variations in the design of its bridges, including a probable left-handed ratchet-wheel screw. It is unclear what differences exist between the Unitas 234 and 444 movements, as they seem to be catalog designations primarily denoting varying bridge shapes.
The Fontainemelon 72-2N features the following functions:
- Stem wind and set
- Sub Second
