    Anyone know if this gyromatic movement is in house?

    I'm looking to find some parts for this movement but I can't seem to find any information online about it. I'm assuming it's not an in house movement by GP. If anyone can help with finding parts I would greatly appreciate it!

    Don't know if this is any help but apparently the movement number is 480-369 (engraved in the movement). The only thing I found was this database: MATERIAL CGI UTILITY It's listed there as "GP 480-369 GIRARD-PERREGAUX MECHANICAL MOVEMENT"
    Based on that it might be manufactured by GP. Maybe you could ask more from the company: Jules Borel & Co. | Watchmaking Supplies, Parts, and Tools

    The base could be an FHF 905, or from the 905 family: bidfun-db Archive: Watch Movements: FHF 905

    Thats right, FHF 905 as a base.
    Sometimes GP introduced certain changes, as in Peseux-based and others base movements,
    although mostly of the differences were on the wheel train and escape/balance parts.
