I am correcting a deformed hairspring and need to set the curve for the regulator pins. De Carle mentions using curve-forming tweezers, which I cannot yet find. What are the alternate practices for forming this curved portion of the over curve?
Question for those who work on Vintage Timex watches:
I've restored several Timex pieces from the late '60s to the late '70s. The technique I learned (from Internet posts and tutorials) say to simply loosen the dial-side balance pivot by unscrewing it 1/2 turn prior to cleaning the entire movement in an ultrasonic cleaner. This method contradicts the official Timex service manuals, which state that the balance should be removed, cleaned separately and reinstalled. Thus preventing the hairspring form being damaged in the ultrasonic cleaner.
My experience is this:
Leaving the balance in place (slightly loosened) is much easier and will work on the standard movements used in the '70s (M24/25, M32/33, M104, etc.)
Attempting the same method on movements from the '50s and '60s (M22, M29, etc) will result in a kinked hairspring that is damn near impossible to un-kink.
So my question is this:
What do you experienced Timex restoration experts recommend? Leave the balance/hairspring in the movement for cleaning, or take it out to soak in a separate jar?
Is the potential for hairspring damage greater when removing/reinstalling the balance - in comparison to leaving it in place?
I've messed up a couple of vintage movements that I really wish I hadn't. I don't want to make those mistakes again.
Thanks for any insights!
I recently had the pleasure of finding a damaged hairspring needing care. My first! It’s an inexpensive orient watch, gaining 20 minutes a day. I am taking Mark’s fault finding course, and have other inexpensive hairsprings to practise with. I also got some vintage tools I’d love to use. Until now for me levellers were only the Oliver Cromwell people, but ebay never ceases to surprise...
I could pass the first stages of correcting the coil, with two tweezers. But could not find a use for the vintage tools. Could you help me to figure it out?
Picture 1 is the bent hairspring
picture 2 and 3 the box of tas levellers
picture 4 is the hairspring suffering under my tweezers now
picture 5 shows the tip of the tools
picture 6: from De Carle. Would this be the purpose of the levellers? The overcoil?
Is there a 'golden rule' relating to relocating a hairspring onto a balance staff with regards to getting zero beat error after it has been removed for attention. I usually take pics or use marker pen but sometime forget!
Hi all. I have a question about the fragility of hairsprings. I’m completely new to watch repair, and have started by regulating my mechanical watches (Seiko 7S26 and Orient F6922 movements). While adjusting the rate with a wooden dowel oriented parallel to the balance wheel, I have accidentally lightly grazed the hairspring. It was enough pressure to stop the balance wheel, but there appear to be no negative consequences. Both watches keep great time and have good positional accuracy. And according to my timegrapher the beat error and amplitude were not affected.
So should I just chalk this up to good luck? Or could there be lurking damage I’m not seeing?
Update I discovered the setting lever when crown is pulled all the way out does not engage because (see picture below) the post on my timing lever is gone so the lever was not secured at axis point which limited the range in which the lever could full extend. I ordered a new one should be here in a week. I will keep you updated, what I think happened is someone pushed the setting lever post to allow stem to insert or remove and they pushed it to hard and broke it.
There is a Jasco made Naphta sold in hw home improvement stores in the US. It's described as being the thinner for varnish and enamel. It also says that it cleans greasy, waxy, oily surfaces and machine parts. Would this be safe to use on watch parts including balance complete?
My name is John but you can call me Jack. I am new the group here and have been a hobbyist repairer for the past 2 + years. I mainly stick with mechanical watches but from time to time I will tinker with old quartz Seiko watches which I love. A current project that I have been trying to get down is a Seiko 4336 8129. This watch has been fighting me from the start. Well the movement was dead due to a broken pivot on the motor. So I sourced a replacement movement. Next Crystal was cracked so I removed the broken glass but can't figure out how to take the top bezel ring off. I have some pics. This poor watch has had a rough life. I was trying to bring it back!! Thank you for reading my tale of woe!!
I am looking for a camera with a macro function to photograph my work. I had a 18 or 20 megapixel Sony point and shoot that worked great for super close pics, but lost it in a fire. Dont remember the model but it was a pocket sized camera I could zoom and focus on pallet stones with excellent definition. It was less than $200 US. Now I can’t find a camera that will do the job for less than $500 Any suggestions?
