    Question Vintage Swiss 100?

    So I found this cool looking watch laying around, more or less...

    It says "Swiss 100" and "Water Resistant" and "Shock Resistant" on the dial and has a cool vintage look. The inside of the watch has "Michael Z Berger" engraved on the movement and it says:

    cal 1217

    I'm not sure WTF a Cal 1217 is but it appears to be a Single Jewel Pin Lever movement. I know nothing of Single Jewel Pin Lever movments, so would someone enlighten me?

    Also, does anyone know anything about the watchmaker/watch?

    Is it worth getting the movement fixed up?

    Yes - a cool, kinda funky, watch.

    Seems to be a Ronda:

    Micheal Z Berger seems to have been an American importer:

    Essentially a cheaply made movement. Worth getting fixed up? Probably not - unless you really like it of course.

    Looks like a Rhonda as previous post but the star under the balance looks like a Junghans. Not worth spending any real money on but probably worth a bit of time yourself.

    Sweet! Thank you for the help guys.

    @Marrkick - that reference site is very helpful! Thank you for the links, they have been bookmarked.

    Yeah, the movement is broken. The rest of the watch is in pretty good shape (just needs some cleaning, new gasket). I'm not sure what is wrong with the movement but the winding mechanism is locked up.

    If I'm feeling courageous I may look into attempting to deal with the movement, although I'm worried that this one may be too broken. When I opened the case a tiny screw fell out . I'm wondering if the previous owner had dropped it or messed with it prior to junking it.

    I should add, the day/date wheel sets properly. The main issue I can tell with the movement is that you can't wind it.

    Here is where the problem is:


    Again, I consider myself a huge noobie at watches, so I've never attempted to do anything to a movement. This could be a good start, being that you have to start somewhere.

    I'll probably have to hit the Online FAQs and references!

    Ronda used a star - very like the Junghans star - with RL inside. See:
