Hey, so I have a question. I've got an Invicta dive watch with a NH35A movement here that whenever I unthread the stem and crown as it is unthreading the date starts changing. Once its unthreaded I can change it to the 1, 2 and 3 positions and set and wind it accordingly. How can I fix this and what is causing this?
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 am about to work on a vintage citizen watch.
I removed the movement from the case but I am stuck on removing the automatic rotor..
It seems that my screwdrivers won't do the job..
Any advice would be helpful thank you.
Hello I had a chance to acquire to two watch movement+dial sets which are from JLC and AP
However, I am having trouble finding cases to fit these.
Could anyone help me find cases that would fit these movements?
Non genuine cases are OK.
Can anyone please help me figure out how to fix the pendulum in this old Welch wall clock? There seems to be a suspension spring mount missing and there is no spring, crutch etc. Just the pendulum rod with a slot in it and a hook on the top. From pics on line I can see that there should be some sort of brass rod crutch assembly from the slot but I have no idea how this attaches or interacts with the pinion what the hook on the pendulum attaches to and how/if a suspension spring should come into play. Any ideas anyone?
Recently I got a 7t32 Seiko which was non running. Normally I would just swap out the movement but after just recently watching your videos I decided to repair it. That involved getting another non runner for parts. Anyway I tore down the watches and was able to get one up and running as it should. Just wanted to say that your videos were very helpful in encouraging me to give it a try.
As with so many things, there's no good or wrong. This has been debated for decades and it won't be settled with 1 picture. The best thing is to have multiple sets of screwdrivers so you can use the best one for the job.
The picture makes sense but only because the one on the left is a perfect fit. If the slot in the screw is only a fraction wider, it doesn't work. So, you'd need a different screwdriver.
