Service: Junghans Max Bill Calibre 83

IMG_2505

A client sent in his lovely Junghans Automatic with a dial designed by legendary Bauhaus designer Max Bill. It’s preforming a little erratically and could benefit from a service.

Movement is Junghans all in-house calibre 83.

I start by removing some of the winding mechanism while the movement is still in the case.

Here you can see the hands and dial removed.

A very nice detail is the jewel barrel bridge.

Here you can see the gear train layout.

Here the movement has been cleaned and ready to go back together.

I have cleaned and oiled the old mainspring as I could not find a new one.

I see that the balance swings freely after oiling. Note the special shock protection system used by Junghans.

I start putting the gear train back in place.

It’s a little tricky to fit the train bridge in place as the third wheel has to fit inside a slot between the centre wheel bush and where you place the central seconds pinion.

This movement is in pristine condition.

Winding/setting mechanism back in place.

We now have a running watch. I have also fitted the winding mechanism. This movement is fully jewelled and top quality all over.

Watch is preforming very well.

I’m now ready for the dial and hands.

Movement goes into the case looking great.

I finish by fitting the oscillating weight

Very nice watch with an unusual and funky movement.
