The Valjoux 724 is a hand-winding chronograph movement with GMT function in the Valjoux 72 family. The GMT function uses a central 24 hour hand that can not be adjusted independently and thus requires a rotating bezel to read. Cal. 724 was replaced by the higher-beat rate Cal. Valjoux 729 around 1974.
