SEIKO AUTOMATIC WATCHES: TROUBLESHOOTING
If your new automatic watch is running too fast or too slow or seems to have stopped, do not panic. An automatic watch is an investment of time and effort and unlike quartz watches (battery operated) it may take some time to start keeping good time. This is true especially for lower range automatic watches (i.e. not “chronometers”).
For your watch to start keeping good time, the main spring needs to be completely wound first. The way to do that is to use a watch winder or shake and wear the watch continuously.
There are some simple steps you can take to regulate your watch. Take the watch off at night and place according to below:
1. If your watch is running slow: lay it flat with the dial up.
2. If your watch is running fast: lay the watch vertically with the crown downwards.
3. If your watch is running too fast: lay the watch vertically with the crown up.
If you watch is still running fast or slow by a large margin the most likely cause is that the mainspring may have gotten itself caught. To get it freed up try this: Place the watch on your palm with the crystal down and slap the watch. If this freed up the mainspring it should start keeping good time.
