Valjoux 7733

Updated version of the Valjoux 7730 introduced in 1969, featuring slight hammer modifications but identical specifications. Base movement for the entire 773x family. Hand-wound cam-operated chronograph with 30-minute counter at 3 o'clock and small seconds at 9 o'clock. Produced until 1978. Served as the foundation for the legendary automatic Valjoux 7750. After ETA introduced the 7750, the machinery for the 7733 was sold to the USSR, spawning the Poljot 3133.
