I took my Seiko SKX009 out of the drawer today and adjusted the time. As always, I :
- Unscrew the crown and pull the crown to position 1
- Adjust the day and date to yesterday's day and date
- Pull the crown to position 2 and cycle the time until the date changes, then set the correct time +1 minute
- Wait until the seconds hand reaches 0 and turn the crown backwards to that I manually "hack" the seconds hands to stall at 0
- Turn the crown forward a bit once the seconds are synchronized with another clock so that the seconds hands gets released and going ("unhacking")
- Push the crown back in and screw it back
After a while throughout the day, I check my computer clock to see how much my time has drifted and I see I am 3-4 seconds earlier so I decide to synchronize again going to the next minute and waiting at 0 seconds. However, to my surprise turning the crown backwards (position 2) doesn't stall the seconds hand anymore. This is the first time this happens to me in months and months of wearing and adjusting time on this watch.
What is going on ? What causes this ? Any fix that could be done without bringing it for a full maintenance check ?
Let me know if a video demonstration would help understand my problem.
