The Valjoux Cal. 88 is a hand-winding chronograph movement in the Valjoux 72 family with “triple date” and moon phase. It was used in upscale dress watches and continues to be desirable due to its functionality and the beauty of the components on the back. It was produced from 1947 through 1974. Cal. 88 was replaced by Cal. 886 in the 1970s.

It is said that 13,218 examples of Cal. 88 were produced, much higher than the similar but simpler Cal. 72C.
