Movement Serial No.:
Case Serial No.:
I purchased this watch as is missing a crown and said not working. I got a battery from the local jewer but is was opened and I do not think it was new. However the watch is running slow and the day/date is not changing and the hands sometimes stop at the 1/2 past Mainly). I bought a new accutron stem and it seems to stick out to far, as if it the problem with the day day not changing .
I would appreciate any suggestions on whats wrong, I am able to fix it if it is not extremly complicated. Thank You in advance.
