Garagesale find Vintage Swiss made Harvester Calendar Watch

[iKokomo]

I just got this in a Harvester Calendar Mechanical Watch (and a Pierre Cardin Quartz watch) for 1 USD and I was wondering if anyone knew anything about this watch? I love to find out the history of watches. When wound up it seems to keep very good time!

There is a slight problem with it, if anyone can help. There seems to be no way to change the hands on the watch. When I pull out the stem, it comes out pretty far, but when I turn it, it still winds the watch instead of changing the hands. I am not sure if there is a special way to change the time / date?

Thanks a lot!!

'One Jewel Wonder' is what I like to call these watches. Just got in a box full of them and one looks just like the one you posted.

can't say why yours is not setting the hands other than to say only way find out is to open it up. Not any value to these just fun to tinker with.
