Hello all,

I bought a Buler 17 jewel automatic Jump Hour watch from that notorious auction site recently. 

It was said to be not working and in need of a new balance wheel - maybe.

Well, it certainly had/has a problem. The hairspring was detached and wrapped around the auto rotor pivot. On top of that, the regulator was lose and there was nothing on the balance cock to anchor a hairspring stud. All rather strange.

Anyway, I have dismantled the movement, after some difficulty with the minute dial/disc, and ordered the correct (I hope) balance components from Cousins Material House.

What I was wondering was, does a service manual exist for this movement (BFG 158 31/7) that I can use as a reference?

Thanks, Andrew
