Good luck.

Thank You...I might be picking your brain later. I was careful to remove the regulator 1st and unhook/unscrew the balance wheel hairspring before doing anything else. I'm looking into a product called One Dip to see if there is a consensus on its beneficial use.

I had a bit of luck while looking for parts movements and picked up what looks like a NOS round case bumper. I'm not sure if it's a 607 or a 618 because I'm trying to locate a tool. I thought a "screw-ball" would do the trick but it is really stuck.

Beautiful though and almost/maybe 70 yrs old.

Now for cleaning...

1) Zippo ultrasonic bath for 5 minutes for everything except the escape wheel, pallet fork & balance/hairspring.

2) Remove from bath and peg wood all jewel holes & anything else that looks dirty.

3) Zippo ultrasonic rinse for another 5 min.

4) One-Dip escape wheel, pallet fork & balance+hairspring. Hand clean end stones & jewels on regulator w/ One-dip also.

5) Treat escape wheel & pallet stones with Epilame.

Epilame did not exist at the these watches were made, yet they could attain remarkable "railroad" precision. One wonders if it is really needed for beginner then. 

In my opinion a better approach would be to avoid smoker's products and maybe use a specific product to brighen the movement.

All clean and waiting on a spring winder from the UK. I started to assemble it but had to stop.

Everything went well except I think I'll wash the barrel & lid with the main plate next time because they were so dirty that they needed an additional rinse. 

I found 3 tiny screws in the dirty solution that I didn't remove from the watch. That was puzzling. They look kinda like those screws on the balance wheel and are about jewel cap size but are steel. I never used my orange (0.05mm) screwdriver once but they are that size with a really pointy end.

Also, the yoke spring was horrible looking and appeared home made. It also looked like someone smashed it in there with a center punch & was a real problem to get out. Not sure what I'm going to do about that.

Are the screws for the dial?  They vibrate out sometimes.

They have a shoulder and are smaller. The only screws I've seen with a sharp point. No clue where they came from.

I did ultrasonic my oscillator bridge but the jewel cap screws are still on it. Plus, there are 3 of them???

The most satisfying tiny little click was when the train bridge dropped into place. I was tickling it for so long that peg wood fibers were accumulating on the gears. (about 30 min)

Next up was oiling the center wheel and I totally messed that up. I approached with a large drop of 1300 and it sucked it in so fast that I couldn't pull the oiler away in time. Lesson learned. No way I'm pulling the bridge off to clean the excess oil. I tried sopping it up with rodico but I'm pretty sure there is still too much on there.

The 9010 went fine. I switched to a smaller oiler and only put enough on it to lubricate the bearing. Same thing though, it sucked it in very quickly.

The pallet fork & cock where easy. Still waiting on the winder from the UK.

as you're a beginner it seems like may be perhaps rather than spending money on Epilame you could probably find something else to spend your money on better.

Then the second paragraph above cryptically at least it was cryptic for me is indicating he should look at some of the discussions we've had on cleaning products. It's amazing what these modern cleaning solutions for watches can do for you. Because spending time and effort with marginal cleaning fluids long term is not going to have the desired results you want and even if you do use surface treatment on a few components the other components are going to have issues eventually.

Yes...I think I walked into a discussion about Epilame that was over my head for a beginner. I also found the topic of cleaning solutions to be very confusing and so I went with something I thought was simple. Everything is new to me and I'm trying to make sense of it all. So far I have not destroyed or lost anything so I'm feeling pretty good about that.

IT LIVES!

I haven't done the 9015 yet but the little fellow just really wanted to tick again.

The winder came today and it's good that I had an old spring to play with because this happened twice when I was trying to reposition my fingers to feed the braking attachment into the winder. I got the hang of it after a few tries and my new spring went together without too much drama.

All back together & a new strap.

Apologies to Markr, the screws were from the dial & the 3rd one was the hairspring stud retaining screw.

The timegrapher results were mixed. I have to work on correcting beat error & getting better at oiling.

And yes...It bump winds!

    • I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong. 
    • Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.
    • this is something I've never quite understood about the some of the Swiss companies. In 1957 Omega was using 9010 for the keyless parts with epilam. there's been a slow migration towards using heavier lubrication's but still typically oils and epilam to keep them in place. When it seems like 9504 works so much better.  
    • OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.
    • Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.
