I've said it before and I'll say it again, "Timex, takes a lickin and keeps on tickin". Considering the watch has no value, unless sentimental, then unless it is for your own interest, it is probably not worth the time and trouble of repairing. I always found Timex difficult to work on as there are no seperate plates for balance, train wheels, mainspring etc. everything is held between two plates. Timex are almost bullet proof and will survive years of brutal treatment but I don't think they were ever designed to be repaired. Good luck with whatever you decide.
