I would love to see a video or photographic walk through of the dissassmbly and assembly of an Omega 861 (Early Speedmaster). I have to restore my personal Speedmaster (given to me new in 1974 by my parents). I have worked on several chronographs in the past but with guidance from books or videos but I would be much more at ease with visual guidance. I looked everywhere for the 861 takedown and couldn't find any detailed work. I also searched for the similar Lemania 1873.

Have a look at Lemania 1873 in the forums walk through section . Same movement. 

Knowing that they were essentially the same movement I had already done a page by page search and a system search for 1873 and all I found was Brian3's interesting post concerning the manufacturing of a part. I repeated the search just now and still come up empty handed.

No walk through of the Omega 861 or Lemania 1873 that I can find. If I am somehow missing the thread would you please offer a link?

Thanks!

My fault as i didn't read the whole thread.i thought is was a walkthrough? 

As you say i can't see anything about either the 861 or the Lemania

1873?

Have you search the net for Tissot cal 27? Same same but different. 

The only services with pictures i can find is watchguy.co.uk . He has done both Lemania and Omega and Tissot.

Thanks rogart63. I'll start searching today. I'm not highly concerned as I already know where the eccentrics are located and how to adjust the chrono finger and jumper as needed.

A walkthrough is one way to keep me from over reaching and going too fast. I have made mistakes born from overconfidence.

You are not the only one?  It's great that someone done the mistakes before i do them. 

Would be very nice to now how to service a 861 movement. Or a Tissot cal 27 . Have one that runs okay but will certainly need some attention in the future?

      Movement holder made with 3D printer

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      Setting lever spring

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.

      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.

      Epilame / Fixodrop

      By JohnR725 · Posted

      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.
