Vintage Girard-Perregaux Jumbo – GP 03 (AS 1130) Service ‪@20thCenturyWatches‬

In this video I service a rare vintage Girard-Perregaux jumbo-size wristwatch powered by the Girard-Perregaux Cal. 03, based on the legendary A. Schild AS 1130 movement. The GP 03 is a 17-jewel, manual-winding movement based on the AS 1130, with Girard-Perregaux-specific plates, bridges and finishing. What makes this particular watch especially interesting is its unusually large case size for a vintage watch. Oversized watches from this period are particularly striking today, when much smaller case sizes were common. 🔧 Watch: Girard-Perregaux 🔧 Movement: Girard-Perregaux Cal. 03 🔧 Base movement: A.
