    Longines Cal. 502 where can I find info.?

    Apparently this is a Valjoux movement. Saw some potential references to the 7750, but from visual inspection, it didn't look to be the same.
    Want to know if this is a good quality movement, one that is dependable.

    I spent some time at Dr. Ranfft's archive and I too found nothing... hopefully others will know more. This is a moonphase isn't it??

    "The watch has to be surrounded by a history.
    You need more than just a great design. You need to create an atmosphere around the product.
    Who is the company behind it? Why are they using this material?
    People need to be able to identify the watch with themselves. It's based on emotion." - Ralph Furter

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    Chronograph, date and moonphase.
    Because this Valjoux movement is 'finished' by Longines it will be a cut above. If it is in good
    servicable condition then it will be dependable but with any vintage watch condition is everything.
    From this single pic the movement looks good and unmolested but can't really tell much more

    Yes indeed, chrono, date, and moon. It's a fine looking watch, just wish I could get more info. on it.
    Hard to determine if a watch is worth what's being asked.

    Would be great to get an idea of production numbers and quality of the piece. Anyone know of a good place to get that info.?

    If you had the serial number, you could contact Longines directly.
    But doesn't seem to be apparent in that pic.
    I've got more Converse sneakers than watches, but it is a close race.

    Actually no, it's for sale on the bay, no limited edition number. I happened to have seen the one in the link you provided listed too and wondered what the story was behind the number. I'm assuming it's not a limited edition, maybe part of some special order?

    Looks to be a Late 70's early 80's Longines...looks original. But for that price it should be nicely cleaned and running tops.

    The movement is a Valjoux Cal. 7733:

    bidfun-db Archive: Watch Movements: Valjoux 7733

    ...if it has only a minute totalizer, or a 7734 if it has a date feature or a 7736 if it has an hour totalizer as well (or even a 7737 if it has a regatta countdown feature). Definitely seventies.
