First Mechanical Fix.

[fjseal]

My first 'wearable' repair was a quartz watch, but I'm happy to be able to wear this, an automatic which I liked the look of on e-bay.

It has a Felsa 1560 movement, and the winding rotor is retained by a neat little split-spring washer.

 

 

I think the only thing wrong with it was it needed a clean, so it was good for a beginner. You can see that the crown is very worn, so will replace it soon.

 

The wheel train bridge took a lot of patience to position, but it finally fell into place at a quarter-to-eleven at night, so by then I deserved my beer!

 

Does anyone know what the purpose of this little cam on the winding wheel does...in pic the spring is disengaged, but when you turn the rotor it just seems to rub against the teeth whichever way you turn the rotor.

 

Regards,

Frank.

Hi Frank,

 

I believe it is a by-directional winding solution, so when the rotor turns one way, the cam engages the cog of the correct ratchet wheel and let the other alone or blocked if you will, and vice versa when it turns the other way. That way it benefits of all the possible movements of the wrist to wind the watch, i.e. both ways.

 

Cheers,

 

Bob

That has to be it, Bob. It's just another example of what impresses about horology. I've seen complex aircraft close-up, but this micro-engineering continually gets my admiration.

I do know what you mean.... This is Seiko's  "Magic Lever " Winding system...
