I have a watch that has a Miyota 2415 movement. I replaced the battery and it started only after I pulled out the crown to set the time. About an hour later it stopped, I went through the same steps again (also checked the new battery, OK) This time it ran for about 18 hours and quit again, again as I pulled out the stem it started running and is currently running also keeping Almost perfect time _2-3 sec in 18 hours. Can anyone tell me whats up. Was there a reset to be done? Or is the movement bad, which I found for less than 10 bucks. I also checked and the battery is in tight. Sorry for the crappy pics.
