Hi. I got myself a 40mm Seiko NH70 diver watch from DWC. I tried installing it and it was working. However I noticed that oncd awhile the second hand got stuck on the minute hand. If I tap the watch gently, it will be able to move pass it. Can someone advise what is wrong?
One of your hands isn’t level, and the second hand is getting stuck on the minute hand. Easy fix; pop the movement out, put it on a level surface, look at it from the side. Each hand should be parallel. If the minute hand is at an angle, you can GENTLY nudge it with tools without removing it. I’ve done it just using the plastic hand pusher tool against the tip of the hand, but I’m not stressed about leaving tiny scratches. Some people like to place their hands during install with rodico to avoid scratching, so I assume this could work similarly.
If it’s the second hand, place the hand pusher tool on top of the second hand as though you’re installing and with gentle pressure, lean it the correct direction.
Rotate the hands a quarter of the way and check clearance again. Then another quarter, and another.
