Not something you will see every day, and as it’s a rare Junghans, it belongs of course to Torsten. The watch has a great looking black dial, red second hand, and, above all, a power reserve indicator at 6 o’clock.
Performance isn’t that great, and a service is in order.
First peek at the movement.
The bottom plate with the power reserve indicator.
The hands need new luminous compound.
The auto winder gears.
The base movement with the auto winder removed.
And the gear train below the wheel bridge.
The mainspring barrel has a set of gears to drive the power reserve indicator, which has to capture the angular difference between the barrel and the barrel arbor.
A closer look at the gears.
The mainspring has definitely had it. Now I can take the bottom plate apart.
All goes into the cleaning machine.
And I start off with a new mainspring as usual.
The mainspring barrel looking nice and clean again.
Before putting the barrel in, parts of the bottom plate have to be reassembled.
The auto winder gears are in place.
And the bottom plate is complete.
Nice amplitude again.
I case the movement and put the rotor on.With a replated case and the new luminous compound, the watch is looking quite spritely again!
