Wanted to put this out there for some of those more knowledgeable members. I have a JF V5 15400 and the second hand stops at the same spot all the time, even at a full wind. Long story short is one of the screws was lost on the bracelet. I found a source to get a new screw but it took almost a month to get. I’m the mean time my watch was sitting in my watch box face up for that entire time. Screw came I installed it but when I went to wear the watch the second hand is stopping at the same spot every revolution. I tap it against my hand and it starts again only to stop at the same point the next time around. The watch worked perfectly before I let it sit for a month. My question is could it be some gunk or something stuck in the gears? Is it too cost prohibitive to buy a new movement or get it serviced? It’s the myota 9015 I believe. Any help or recommendations would be greatly appreciated.
