Held it quite puzzled for a moment in my hand, when I decided to put this one on and scratched my head ... how did it work again? How do I pre-wind it manually??? Looking at the back at the crown I was thinking: Was the crown in the back for winding? ... ...  

... but not for manual winding ...  

So when you put it back on, it will have a certain power reserve to get you going.

I have got pictures from the hoock that is catching the rotor, to end the automatic winding, but I could not find any pictures from the parts that bring the movement to a premature hold. Have you got any pictures or do you know about an article that is sh... 

The mainspring in the barrel is pre-tensioned. As this watch doesn’t have a manual wind, the engineers thought it would be a good idea to leave a residual tension in the mainspring, so that the watch will start up instantly when slightly wound by the auto... 

I came across this article. I found also a German watchmaker's article, who showed pictures of tge movement whilst servicing a Futurematic. I saw pictures of the movement parts you have quoted. The stop at the top end of winding is clear to me but not the... 

If you imagine the main spring in the barrel, there is a plate above the spring. The spring is wound one and a half turn, and two tiny screws are inserted to prevent it from winding completely down. The same contraption drives the power reserve display - ...

and well conceived.

A total surprise finding at a local, traditional watchmaker. Best of all: a very fair price and the watch has been freshly serviced, too. I gave him my mobile number after buying this one .... 😀

A very cool watch - but I am biased Cheers JML

the return/revenue was not as expected?

And a picture of the 1955 Catalogue. ...  

Seldom seen in good condition.

Yes, the condition struck me and the fact that it is from the late 1950 ies. A great piece of watchmaking and very affordable, too.

The dials are sadly often in poor shape.

The "constant force" character of the watch is showing its capability. Thank you for looking.

On so many levels
