I have several Bulova 17AH pocket watches which I am in the process of servicing and have ran into an issue trying to wind the mainspring. None on my mainspring winders seem to work for this spring, the rod with the pin which is on the crank (not sure of the propper name) is either not the correct size to fit or the one which does fit has a long protrusion instead of a pin and it is too long to catch on the opening/hole on the mainspring.
I currently have three sets of winders and non seem to work on this spring. My winder sets are a Marshal pocket watch winder set, a Watch-Craft wristwatch set and a Watch-Craft pocket watch set with two cranks each a different size.
I was wondering if anyone here has worked on this movement and what mainspring winder do you use for it? Thanks in advance.
