    Spoiler Alert : Another newbie trying to determine age of a Girard-Perregaux

    All,
    I'm just getting into older movements and watches as art, and have picked up a few. The design of the watch itself looks old -- My weak guess from was late 30s, but the movement... I don't know, it sure looks clean.. Makes me think much newer?

    From reading, it seems that the serial number is useless with G-P to link to a date, and G-P isn't terribly helpful with this info either, so I was hoping that someone here may have a better guess than me. Not looking to sell or appraise, I'm just trying to determine an age and perhaps know what to call it (model). Any thoughts?

    Thank you for your time and kindness!

    Probably late-50's, and I don't really see anything out of place with that age. But with GP, it could still be a marriage--it's hard to know for sure.

    The movements is a caliber 18.09 (the first four digits of the serial number)...

    bidfun-db Archive: Watch Movements : Girard-Perregaux 18

    ...which was a modified Peseux 330, according to Ranfft. It has Incabloc shock protection, which makes it post-war for sure, but the movement was used in the 50's in any case.

    The case is gold-filled with 20-microns of rolled-gold plating, which is consistent with the steel back. The markings in the back appear to be stamped rather than laser-cut, which is appropriate. There are also some scratched marks by past watchmakers when they serviced the movement, which is also appropriate. The domed acrylic crystal is also fine for that age.

    And the dial design is typical of the late 50's or early 60's, and was certainly used by GP in those years, including the use of gold hands and markers on a brushed silver dial.

    I know from experience that it's very difficult to photograph the dial label through a plastic crystal without all manner of distortion, so it's hard to know for sure if it has been repainted (or perhaps painted on a fresh dial replacement).

    The crown looks like a replacement--there is too little wear and it's a little too wide for the time.

    Whether this watch has lived its whole life in this combination is hard to know, but it's still a real GP movement in the sort of case it would have been in back in the day. If you like it, keep it and don't worry about it. If you are hoping it's an investment, then only a first-hand appraisal by an expert will provide what you want to know.

    Hi,

    This may be it, a modified Peseux 330 movement or family thereof. It would date it at circa mid 50s .

    Regards,

    Really like the patina of the dial.

    Is it patination or reflections? The dial appears to have a starburst finish which would indicate it is original.

    After Denney's response, I've got nothing, except that this watch is a pretty common 1950's GP. I associate the GP Gyromatics with the 60's.

    Nah, the Gyromatic was their generic name for full-rotor automatics. Here's an ad purportedly (and plausibly) from 1951:
