The Tissot 762 is an open face calibre watch movement that features a unique crown mechanism with a rocker bar and a ratchet located on the backside. The crown wheel, although present, does not serve any specific function. There is a possibility of a left-handed ratchet-wheel screw. Also, the 220 and 283 variations of the movement exhibit differences in their bridge shapes. In terms of functions, the Tissot 762 supports stem winding and setting, as well as a sub second feature.
