• Compatible calibers: Girard-Perregaux manual wind movements Cal. 03 and Cal. 03BF
• Condition: New Old Stock (NOS). Factory-fresh, pristina condition, safely packed i our own pacaging.
• Important Technical Note: While the GP 03 architecture historically stems from the AS 130 ebauche, Girard-Perregaux heavely modified the mainplate, bridges, and balance assembly. Standard AS 1130 balance staff will NOT fit this high-grade GP movement. This NOS component is the correct, rare, proprietary Girard-Perregaux speification needed for a perfect drop-in repair and correct amplitude.
