Ok, ive started taking apart my first watch. First of all what the proper term for this movement, geneva, bar?
And its a keywind keyset. Now im ready to take off the center bar, but its not giving easy. The cannon barrel is still attached, but im wondering if the key mechanism is holding it at all. Same for the main spring barrel, is there anying i should be aware of before lifting that out also?February 11, 2014 at 7:58 pm #55736
Have you released the mainspring ????February 11, 2014 at 8:03 pm #55738
And this is the bottom of the balance cock, you cant see it, but the balance spring didnt mount to anything, there is a small hole on the bottom part that the spring thread though,,maybe two rotations,,but didnt mount anywere, is something missing or is that normal for this movement?February 11, 2014 at 8:03 pm #55739
Yea there is no tension on the main springFebruary 12, 2014 at 10:48 am #55737
I would remove the canon pinion for sure.
Then see if the bar will release once the screws are out.
As for the balance, the hairsping has to be “captured” on the end by a stud, and the first coil passes through the small regulating pins.
I’m thinking this one is simply missing ?February 12, 2014 at 12:53 pm #55740
Thanks,,I have to wait for my hand puller to get here before i can remove the cannon pinion, and i just noticed on another watch i just got how the hairspring is captured in that hole with a simple pin. ThanksFebruary 12, 2014 at 4:02 pm #55741
