I am trying to puzzle it out.
Just picked it up to swirl it in my hand and it runs for a few minutes.
But watching it closely I see it stops dead when the second hand reaches the minute hand.
It has stopped on it 3 times since I have just been " swirling it, every time dead on the minute hand.
So I think that something is sticking.
To add to it, this is only happening during the " date change" time zone 11pm-ish.
I have just reset the time to the correct time and it is running fine, I had it run fine all day yesterday it was only last night at, as I said, about 11.30 that it got stuck.
Could this be because he has set the date between 10-2pm? Trying to reason why.
So to summarise.
Second hand stops on the minute hand during the date change "zone", irrespective of the PR "volume".
Swirling it kicks it back to life for a minute or two, then it stops on the minute hand again.
Seems to run fine otherwise. It has ran smoothly for the last 2 hours ( set to the correct AM time, but I am sure that at 11:30pm-ish tonight it will stop dead with the second hand right on top of the minute hand.
The date wheel is half way through it's switching over when this all occurs.
As for the power reserve, it may actually be decreasing even when the hands "stick". Not 100% sure will check tonight, as I'm just letting it run at the moment.
