Valjoux 7734

Valjoux 7733 with added date complication. Produced in Switzerland until approximately 1974. The date function adds 0.65mm to the height compared to the base 7733 (6.65mm vs 6.0mm). Features hours, minutes, central chronograph seconds, running seconds subdial at 9 o'clock, 30-minute counter at 3 o'clock, and date display. Uses a cam-lever (coulisse) chronograph switching system. After the introduction of the ETA 7750, the 7734 production machinery was sold to the USSR, leading to the creation of the Poljot caliber 3133.
