The 861 movement is extremely dirty.
Removing the case ring shows first signs of rust..
Yes it will get a new stem!
Wonder how it looks underneath the dial.
Dial is covered in corrosive particles.
Not too bad! Only the setting lever screw, winding pinion and sliding pinion needed replacing.
I start taking the chronograph layer apart.
I’m down to the base movement.
The winding pinion has fused together with the sliding pinion.
Movement first gets a manual clean and then two rounds in the cleaning machine…
I see that the balance moves freely after fitting shock jewels.
I put the gear train back in place.
Looks a little better with new parts..
Setting/winding mechanism almost back together.
I clean up the setting lever spring and we can once again wind the watch!
For the first time in a while this movement is ticking again.
I start putting the chronograph layer back in place.
Now that looks a lot nicer than when I started!
Resetting the hour recorder was almost impossible and I noticed the corroded surface on the hour recorder stop lever.
I file down the surface and now we’re back in business.
Movement now working like it should and ready for the dial.
I cleaned the dial up a little and applied new aged compound (sorry patina purists) I test the hour recorder a little while making sure there is no creep.
Watch preforms well after settling.
I’m happy with how this watch turned out!:)
If I may,
What is creeping?
p.s.The dial turned out great! Also the rest 🙂 How did you take off the old lume? Microscope and elbow grease?
It’s when the hour recorder moves when not engaged. Yes Compound is both removed and applied under the microscope.
Thank you! That is one steady hand under the microscope!
