My timex f1 (that i think have a m25 movement) have Teo problems, the first is that when the Watch start, It stops After a few seconda, and the seconds is that when i load the main spring after some rounds of crown the main spring snaps and returns without charge.

I've arleady clean all parts of the movement, but i don't know what parts is ruined and be changed.

Thanks.

that looks like a Sprite model.   the N44 is a factory number and has no bearing to this topic.  is there a date ring?  if so it would likely be a M25 no date ring than m24.  still a guess without seeing the dial.  aside from this, it sounds like the mainspring is the issue. But, that would have to be confirmed by more investigation.

If your intention is to repair the watch you will be in for an interesting journey.  Finding NOS replacement parts for vintage Timex is a challenge here in the US and I know it is even a greater challenge elsewhere. Best suggestion would be is to find a donor watch that has same movement and exchange them.    Good Luck with the journey!

Thanks for the reply,

there Is the data so i think Is a m25.

When i load the main spring the click seems ok, but the mainspring snaps, so i think that i try to change the mainspring and the barrel arbor, but the only way to have this parts Is buying another complete Watch.

If you know where to buy this piece tell me.

I've already disassembled and assembled this movement but Is very difficult.

Thank you again for the reply.

I leave you a photo to make you understand why I want to restore it.

I have seem the issue where the outer edge of the spring slips against the barrel.  It could be either the tails or the small dibble that catches the tail is worn.  Either way this not an easy fix since it requires a full tear down and rebuild.  So what to do about the required parts?  Buy a lot of 'fixer uppers' or 'spares repairs' as they say across the pond.  What happens as a result of this of course is now you will want to repair them all.  BTW:  The watch shown is a European model from what is commonly named the "Sports Series".  This is distinguished by the use of Meters rather than Feet printed on the dial.  Need a NOS mainspring and barrel?  I have them but shipping cost more than the part.

Finally i've repaired the movement and now the Watch runs, the problem was the mainspring that slipped against the barrel like as jerseymo said.

I've also found an old advertisement, but i'm not sure if the Watch of the advertisement and my Watch are the same, can you help me?

      Chronograph Pusher Rod for EB8371-67 Snapped and Stuck in Button. Can't Unscrew.

      By watchweasol · Posted

      Hi. Yes I get it , the slot in the end I’d to allow you to screw the button on whilst holding the pusher shaft. To remove the pusher tube you will need a tool such as the one shown by Richard. I think Ali Express the Chinese Amazon has replicas of the Horotec system for a lot less money, how effective they are not having had to use one. But as you said the way to go is complete removal and replacement, bodging it up will  lead to a repeat failure

      30T2 adjustment of timing washers

      By JohnR725 · Posted

      One of the things that I've been bothered with lately is timekeeping? For instance a 90-year-old pocket watch what so to timekeeping was it supposed to keep? They publish railroad timekeeping but I don't know how well normal non-railroad watches were supposed to keep time. The reason why the question comes up for me is I spend a lot of time at work adjusting watches to keep really really good time  because I have to please my boss where as when the watch was made I have to wonder what kind timekeeping would've been acceptable. After all they typically didn't have timing machines 100 years ago and they were timing and six positions certainly not for the non-railroad grade watch. On the other hand I do get paid by the hour so maybe I shouldn't be concerned of how much time I Spend trying to make everything keep chronometer timekeeping almost. Citing a Delta of 40 seconds for a 90-year-old watch is quite outstanding.

      Is this pallet fork over-locking?

      By JohnR725 · Posted

      That's an interesting question which I don't think I've seen explained anywhere. But I think the problem will go away just about instantaneously. In other words the  coating is really thin and it should go away almost immediately. So the problem should resolve itself extremely fast.

      I experienced that different types of shellac and their ages are affected differently by IPA. Sometimes the shellac dissolves in a few seconds and sometimes several minutes are required. Nowadays I never let shellac come into contact with IPA. It's a hotly debated topic here on WRT if you search. Like John, I don't think you need to worry about the weight of the shellac, but instead that it might start rubbing against something. When I learned how to adjust pallet stones, I tried documenting my experiences in this thread. Hopefully, it can help you. I personally don't believe in the idea of abrading the epilame before oiling so I don't think you need to think or worry about it. The only time I've heard anyone mention this is Alex on the YouTube channel Watch Repair Tutorials but actually no one else. I'm not saying it's "wrong" just that I don't think it's necessary or adds anything.
