This is Bert’s Kiva, and I must say she’s a beauty!
It stops from time to time, and needs a service.
A first look – this is the FB222 movement, made by Förster in Germany.
Very weak amplitude, so it definitely needs a service.
The auto winder works in both directions.
The gear train.
The date change is very snappy and well constructed.
Just the jewels to take out.
And ready for cleaning.
I start putting the wheel train together.
The balance is in, and the movement is ticking.
That’s a lot better!
With a new crystal, the watch look gorgeous again.Bert chose a great strap for it, that suits the watch very well.
I put the watch on the autowinder, and it loses 5 minutes at a time, only to then keep time again. I’m a bit thrown by this, but finally find the problem. The clutch on the great wheel slips only from time to time. As it’s very hard to adjust, and I have a spare great wheel, I swap a wheel with a good clutch tension over, and everything is well.
