Cal. 400 is a manual-winding chronograph caliber manufactured by Cortébert. Introduced around 1932 as a pocket watch movement, it was later adapted for wristwear. The caliber represents an early in-house chronograph from the Swiss manufacturer, reflecting Cortébert's emphasis on proprietary movement development during this period. Production has been discontinued.
