Valjoux 7734

The Valjoux 7734 is a manual-winding chronograph movement manufactured in Switzerland from 1970 until approximately 1974. It measures 6.65mm in height and contains 17 jewels with Incabloc shock protection. Based on the caliber 7733, the 7734 adds a date complication, accounting for its increased thickness. The production tooling was sold to the USSR, where it became the basis for the Poljot caliber 3133.
