Timex M24 Repair Issue (Problem with balance?)

[Shane]

The first thing I do before pulling the balance out or trying to make adjustments institute is pull the pin and see if the spring lies any better.  You might just just have an incorrectly installed pin.  The spring will deform if you put "English" on it when inserting the pin.  For a tool to insert the pin with, I cut just the tip off a toothpick (not the whole tapered end) and poking a small hole in the end with my tweezers.  It gives enough control to avoid undo influence on the spring.  Your spring, on the other hand, has problems.

I believe this is covered in the videos listed above but if you're going to pull the spring from the balance don't forget to mark the springs orientation to the balance wheel before it is removed (it will save you time when setting it back into beat).

Almost anyone on this forum can put their hand on a honorably deformed hairspring, practice on a junk one first (it takes the stress out of the practice).

There are good people here to listen to.

Good luck.

I was able to get the movement that was running slow going pretty good. But no it has another strange issue... It runs strong except for when it is pitched at a certain angle (while dial is facing up, crown slightly angled up and 12 o'clock on dial angled slightly down). At first I thought the hands might have been catching the crystal or dial markers but when I stripped the watch down to just the movement, the balance still stopped oscillating when pitched at that angle. Before discovering this I let the watch run on my table for a day and it was keeping good time. Any ideas on this one? 

 

Also, the crystal is cracked unfortunately. Does anyone have suggestions on generic replacements? Would these properly sized work or would the domes be to shallow?

It could be the hairspring is touching due to gravity. I think that if you were to place it on a timegrapher or equivalent application (a mandatory tool when working on mechanical watches) you would see an irregular pattern. Also you would be able to hear a rough sound in the troubled positions.
