Jumping on the timex train

[PiercePrzybyla]

Hey, new to the hobby and found myself starting with old timex watches. I have found that when I swapped my m24 movement with an m72 movement my second hand will slip and fall to the 6 o'clock position when the face is held perpendicular to the ground. Any ideas for a newbie?

Welcome to the forum.

Did you change the hands between the movements as well? Sounds like the second hand is too big a diameter for the pinion that it fits onto.

However, being that I am quite new as well, I might be talking absolute rubbish.

@Michael1962 I have not. I am using the same hands from the m24. The hand would fit in place and hold tight but when gravity took over it would run downhill the climb back up. As long as I don't have a seconds hand on the movement the watch works like a charm.

[Michael1962]

If you have taken the hands from the M24 movement and put them onto the M72 movement, I would suggest that the second hand bush is too big for the M72 pinion.

That is what I meant by changing hands if I have read your post correctly.

@Michael1962 Okay, I understand what you are saying. I will take a look for other hands see of they will work better. Thank you!

[Michael1962]

With the correct tools, you should be able to reduce the bush size I think. Someone with more experience than myself will hopefully be along shortly with some advice.

first off why are you putting a 72 into a 24?  next, although the cannon pinon and or hour wheel look similar they are not. This is true across many parts Timex used.

@JerseyMoIt was a movement that I was available to get my hands on at the time.
