Update: The demagnetization only helped temporarily, maybe it pulled the wheels into a position where they liked each other. I have to adjust the sub second hand as it is a bit angled upwards and catching the minute hand stopping the whole movement but before this happened there were some wild deviations. HWGIKE#58 Alarm clock, cooked in hot cleaning fluid and oiled gently. This is a movement so I count it. 🙂 A while ago it tried to fly away one day, it was on my windows sill, we had strong wind the curtain flew like a flag and doing so encouraged my clock to do the same... went out and ended up on the roof above the entrance door, its door in pieces but the clock itself suffered no damage otherwise. The original glass was already broken when I received it I still have the bottom part in two pieces. The new "glass" is acrylic. It also had a paper in the back in the case inside but it disintegrated, I still have a little bit of piece of that too. HWGIKE#59 Durowe 870 / Times M84 This particular instance is a D870, when I saw its worn out contact pin I thought that it must be a design flaw, and here we go: https://17jewels.info/movements/d/durowe/durowe-870/ An incredible movement again where the balance wheel drives the train and has two magnets one for the balance wheel/coil and one for the pallet. The magnet for the pallet is basically the "draw" one direction. The coil is about 1.8kOhm and one end is in contact with the main plate and the other end is soldered to a contact pin which is insulated by the means of putting it into a jewel and this contact pin is rubbing against a wire getting the energy/impulse as it is passing. Behind the contact pin there is an "impulse jewel" not sure why is it there... the wire seems to hit the impulse jewel first then the contact pin but maybe it is there only for insulation purposes? I was almost certain that the screw holding down the battery - (minus) clamp had no insulation washer.. i only noticed the green stuff around it coming from battery leakage... anyway the + and - had a shortcut which took me a while to realize.. had to fabricate one insulating washer on my own. The jewel settings were dirty but not it is all cleaned and oiled. The contact pin might work for a while but I am sure it has a short life. It is a front loader the whole thing is held together by the case so it is not possible to regulate it without putting it all together and taking the movement out of the case again, very inconvenient. A wonderful movement but not made for eternity only for the consumer market. -
Is it a crystal or an acrylic and just foggy with age? -
The point I missed to make ! is ; moisture in the movement is the main problem, it can ruin electronic components. -
@VWatchie I believe that function to turn ads off is a Patron and moderator perk as they contribute to the site with money or time respectively. Tom
