It likely features a left handed ratchet-wheel screw, although further details about the differences between the 6437 and 6445 are not known. These two designations are probably used to differentiate the varying bridge shapes found in the catalog. The movement, which was commonly used around 1960, includes the functions of stem winding and setting, as well as a sub second. Some sources indicate that the Unitas/Eta 6497 calibers had direct connection to, or were even derived from the old Cortebert movements used in the original WWII Italian Navy diver watches.
