The Valjoux 236 is a celebrated hand-winding chronograph movement produced from 1974. A higher-beat replacement for the venerable Valjoux 23, it operates at 21,600 A/h rather than 18,000 A/h. The Valjoux 236 was introduced in 1974 and produced through the 1970s.

The Valjoux 236 and 726 are almost identical except that the latter adds a 12 hour counter at 6:00 on the dial.

The Valjoux 236 was used by many brands, notably including Girard-Perregaux, Tissot, and Vulcain.
