    Olympic or Handelsmarke - what to do with these?

    Hello all,
    I am going through my boxes and drawers of watches, and I stumbled across these two watches. I know about nothing about either, and was looking for professional guidance on if either of these are worth repairing. I like both because of their differences. The Olympic I love because of the technicality of the waterproof case, a lot of engineering went into it. I equally like the Handelsmarke, because of its simplicity and apparent German engineering. My quandary is....is either worth spending money into repair? Since I know nothing of either, I thought a little insight from anybody would be greatly appreciated.

    Well, the Olympic has a 7 jewel movement - rather low when fully jewelled movements have 15 jewels - with extensive corrosion. In my opinion not worth repairing.

    The other one is actually a Zentra - 'handelsmarke' means trademark. bidfun-db Archive: Watch Movements: ZentRa-Garantiegemeinschaft e.V. It is also not highly jewelled. It might be repairable if the balance wheel is in good shape.

    Await further opinions of course.

    I'm not going to add much more. That design of waterproof case was reasonably popular at the time and I'm going to suggest that was aimed at lower value watches which fits well with the low jewel count.

    The Olympic has a fairly standard Adolf Schild Cal. AS 970:

    I am not really sure about the ZentRa movement but it might be a derivative of this one:
