Family: GP9000
GP9400 is a manual-winding in-house caliber developed by Girard-Perregaux. It features a constant-force escapement mechanism, which delivers consistent power transmission throughout the mainspring's discharge cycle. First paired with a watch in 2013 after prototype development began in 2008, the movement remains in production. It is notably used in the Girard-Perregaux Constant Escapement timepiece.
