Service/restoration Lemania calibre: 3170

The movement is in very good condition, but the case has some bad corrosion marks and will be sent off to be restored with Replated in Canada

The dial and hands are in pretty good condition.

Hands and dial removed and you can see the winding/setting mechanism.

The third wheel has two driving wheels on one axel, the upper wheel drives the central seconds wheel and the lower drives the forth wheel.

Plenty of dirt around the pivot holes.

The old mainspring.

After some weeks the case comes back from Replated looking like new. I fit a new pendant tube.

The parts have all been cleaned and are ready to be put back together.

The main difference between the 3060 and 3170, besides the plating colure, is that the 3060 has a Breguet Hairspring with a catch device for the hairspring and the 3070 has a flat hairspring with regular regulator pins. Here I can see that the hairspring moves freely.

Here you can see the gear train before fitting the train bridge.

Setting/winding mechanism coming back together.

Movement back together and running. It’s time to adjust the timekeeping.

Thats pretty good in my book for a 50+ year old;)

Movement ready for dial and hands.

The old compound was crumbling, so I replaced it with some aged new compound.

Movement goes back in the case looking good.

Great watch in great condition.

Functional and clean design.
