The Valjoux Cal. 90 is a hand-winding triple-date movement with moon phase. Closely related to the Valjoux 23/72 chronograph movements, it is also similar to the Valjoux 89.

The calendar is quick-corrected using inset pushers: The pusher at 4:00 advances the moon phase indicator, the pusher at 8:30 advances the date hand, and the pusher at 10:00 advances the day and month.
