pocketwatch hairspring

[bobpat]

Well, after 10yrs of clocks, I decided to try watches. Picked up a couple of “dollarwatches” on ebay. First one I took apart, cleaned it and it runs great, second one, well not so good, I broke the hairspring. Now come the questions. It doesn’t have a balance cock, the spring fits between the plates.One end was attached to a tiny bracket with what looks like a taperpin sticking out.. Do they use taperpins to attch these? How do you find the correct replacement spring, Searched online but its not really a well known watch. Can I use the old spring?. I don’t know how much was broken off. I included a pic. Its a large pic, I don’tknow why, but watch is there if you scroll around for it. you will see a l shaped bracket on the right with what looks like a taperpin sticking out the back.. This is just a practice watch but I know it will run if I can figure this hairspring out… THANKS

You probably know this, but I would like to indicate that a hairspring goes with a balance and will have to be vibrated for it. Apart from being highly educating, I would think it is rather involved for a dollar watch.

thanks Jan. It may seem rather involved but I am trying to learn . So the involvement is not the issue. I don’t put a timeline on any learning challenge. Would rather learn on a cheap watch than ruin someones expensive one.I was reading up on the vibration of a hairspring, quit intense but I am game..Thanks for your reply
