As the question was solved so fast by various members - here come additional pics of the CK 3532
I have been searching for this reference for quite a while and was lucky to find a good example with all original condition -
except the winding crown as it seems - so if you happen to have a SS spare one in your parts drawer pls let me know...

Dial is in acceptable original condition, hands are original too.
When the strap is removed you can see the interesting case construction and how long the case is in fact.

An interesting angle of view unveils the inner construction and position of the movement - nice, eh?

And here comes the very reliable and very well known Cal. T17 with the huge power reserve of 60 hours

I guess you want to see a wrist-shot...

This angle of view does not give any hint about the special construction and shape...
You need to change the point of view...

It wears very comfortably due to the slight curve of the case.
Bought this watch about 5 months ago but wanted to wait for a reason to "publish" it - my post # 1200
Enjoy the pics
