    I have one of my Ploprof 600's in for service and have just recieved this picture from my WM. I've had it for about ten years and this is the first time I've ever actually seen the movement.

    Having a 33 million serial number the cal 1002 dates to around 1971 which I believe was the year of introduction for this model, but I was wondering if anyone has a chart of PP serials, or at least more information regarding the first known serial numbers for this model?

    I think your watch might be later than you think.

    Here’s my extract.

    Very early prototypes have the usual 00 movements.

    First movements numbered in the usual way start at 29 million.

    Then 31 million from '71.

    33 million could be '72, '73 or '74 based on serials I've got...I wouldn't consider a 33 million watch early.

    Bear in mind that extract dates are when the watch was built/shipped AFAIK...

    @cristos71 , any other details like the dial or hour hand from yours that might help price together more of the “order?”

    I think for most watches these charts are okay but guess the PloProf was not exactly flying out the door so a larger difference between movement serial and production/casing/shipping than usually seen...

    It is a C-Case with a great dial, the bezel is a service one and the hands I'm not sure.

    Probably due to the price of them.

    There is a HUGE difference in the serial logic for a Ploprof than for example a Speedy. First “production” Ploprofs start to my knowledge at high 31.xxx serials and go to 33.xxx serials like yours. The difference in production year for a Ploprof can be up to eight years from the 32 series to the 33 series.

    The 31 series start in 1971, and the 33 series is seen from 78 - 79. So a huge gap in between. A 32 series is around 1972.

    Confused my numbers in the post above (now corrected) and my records show several watches from '71 with 31 million serial.

    Lowest being 31,243,XXX

    Another reason I was thinking mine 'early' is due to the the dial style, which is of the earlier type.

    Hope this helps a bit. I made this list years ago based on Extracts or sale dates, that I have or seen on the internet.
