Need advice on how to repair this watch.
I received a modded Seiko watch as a gift a while ago and I absolutely love it. Unfortunately recently I have had some trouble with it. The watch stopped working, to which I obviously put a new battery in it, but I am still having issues. I run the stopwatch function on the watch which works perfectly, once I stop it, the secondary second hand on the watch will run normally but will then stop after 10-15 minutes of it running and will not resume until I use the stopwatch function again. Not sure why this is the case, or why it's doing this, but I'm currently looking for someone or someplace to repair it but I'm sure where because it's modded. I considered taking it to the person who made it but it seems they're now defunct. If anyone has any ideas I what I could do I would greatly appreciate it!
