Hi all.  Engineer of 30 years recently taken to watch repair due to a broken ETA 2894-2. The cost of repair was more than the value of the watch so with nothing to lose I did loads of research and had a go.  I have had good results replacing the balance wheel and third wheel and the watch now runs well.  The only thing left to repair is a broken seconds hand on the subsidiary dial (hope that's the correct terminology) so will be looking for help with rebuilding the Chronograph Module.  I understand you are not advised to take this module apart but as I said its scrap anyway so why not have ago. Thanks.

Hi Have a look on gleave & co   Tech hub there is a pdf and on page 24 there is some info on the chrono.
 

Many thanks I had seen that bit. In your experience is that as much info as I can expect and is that because it’s not really a serviceable module. Thanks again.

Just to place things in the right perspective, technical information and parts availability aside, working on chronographs is definitely an advanced watchmaking task. 

 

I couldn’t agree more but as I said the watch is effectively scrap. As I said I have 30 years experience in engineering and nothing has beaten me yet. I am sure with the great help I have received so far I will get there in the end.

      Yes, I was referring to the (jewelled) gear train with HP (most of the time, I use 1300, but when Rolex says 1000, I'll use 1000).

      I suppose it would depend upon what your lubricating with those? for instance what does the manufacturer say about those lubricants? I have a PDF from the manufacture and a rather peculiar statement found on the bottom of the chart. my suspicion is the reason the recommending would be without epilam the HP oils like the spread except when they're in Ruby jewel's with steel pivots. tableEN lubrication 2020.pdf

      Is this a 'hack' ?

      By oldhippy · Posted

      These types of hairsprings become weak with age and very fragile. Which I expect it is that giving you trouble, and that wheel is not the correct one, if it were not bent I don't think the movement would run as the teeth are not the correct height. The problem you have is price which depends on you. It can be repaired but is it worth it to you, because there is little value in the clock. A wheel can be made and hairspring replaced. Or hang on to it and keep looking on ebay which is your best bet for replacement parts or even a complete movement but it will be like finding a needle in a haystack.
