Service Pallas automatic alarm/calibre: AS 5008

IMG_5905

Torsten has sent in, what is in my view, one of the best automatic alarm watches ever made. It’s due for a service.

This complicated beast comes with a nice micro regulator.

I start by removing the auto winder mechanism.

A nice touch is that the auto winder not only winds the time keeping mainspring, but also the alarm mainspring.

I appreciate how they have made both stems identical.

The dial and hands are is in excellent condition.

I now start making my way down the alarm setting/triggering/winding mechanism and the winding/setting mechanism.

I take a lot of photos to help myself with putting the watch back together later.

I remove the date support disk.

Movement is fairly clean, but the further down I get, the more dirt shows up.

IMG_5924

Almost done with the complicated part;)

IMG_5927

I now start taking the base movement apart.

Fairly compact gear train layout.

Old mainspring.

What looks like an infinite amount of parts are cleaned and ready to be put back together.

I start by putting the base movement back together.

The alarm train and hammer is fitted in one unit.

Now the fun begins.

Making slow but steady progress;)

IMG_5988

I put the date support disk back in place.

IMG_5990

Date and week disk comes back in place.

IMG_5991

Movement in the case and ticking.

IMG_5983

Great performance.

IMG_5992

Auto winder mechanism back in place and I’m all done! I find these a little complicated and time consuming, but enjoyable to work on when in good condition.

Very nice watch! Imagine the price these would go for if it had a certain crown logo and Oyster case;)
