Omega speedmaster pro (861) walkthrough?

Question

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?

    • Okay so the cap jewel was placed the wrong way and the dome went inwards... Should've checked that earlier... Thanks for all the answers!

    • Hi Everyone I have cleaned and reassembled a mantel clock, the Westminster chimes work on each of the quarter hours but it does not strike the hour strike. Any suggestions please.

    • If the broach starts to bind in the hole a little oil will help. For your first attempt you have done well. I’m not too sure of the bush you have chosen the hole has very little depth to the pivot and plate. This is why I always made my own. Here are two sorts of bushes that I recommend. Bergeon and KWM I wouldn’t use them. Bergeon clock brooches cutting and smoothing are one of the best, I don’t think they cover the sizes you would need for Longcase (grandfather) clocks I might be wrong. There is another type of bushing when you have experience, that is called invisible, that is when you can’t see that the clock has been bushed.     https://www.cousinsuk.com/product/mantel-clock-general https://www.cousinsuk.com/product/english-clock-bushes
