I have a PAM25 which is just over a year old. I haven't worn it for about 4 days so when I put it on this morning I needed to move it to put some power in it. Since giving it a good shake the small second hand is rotating smoothly as it should, but the minute hand is not moving it's as if the watch is still stopped, but it's not as the seconds are moving and you can hear the ticking... Any ideas?
