I've had this watch longer than any other. Sentimental to me. Always been a work in progress.

An ongoing problem has been there doesn't seem to be enough power to operate all the functions properly unless I keep pressure on the crown, essentially loading the mainspring. (Which I have changed several times)

Have cleaned, checked for interference,  changed components, with no luck. Have even run the basic  movement without any additional complications to no avail.

I would approach this like you said, see if basic module is fine and start adding parts until you notice where there is a loss of power ,

Thanks, but it still the same running just the basic movement. (Valjoux 72c)

Sorry so.you mean power is bad on just the basic movement. If so then you need to start breaking that down too.

 

Removing the balance and the pallet, winding up the watch , what is the winding down like, smooth and fast or does it need help to wind down?
