How to set the minute wheel on a ETA 940.111


Clive

Recommended Posts

 I have been given a watch in pieces  (movement is an ETA 940 111). I have replaced the minute wheel as it had teeth missing and now I am ready to put the dial and hands on. One problem I have is that its a 2 stage stem i.e you pull out a little to get the date to move and then pull out further to get the time adjusted. My challenge is that when the stem is pulled out to adjust the time, at no point does the date move on and so I am at a loss how I determine the tipping point for the date. Is there a known /recommended way of doing this or do I put the hands on and then wait for the date to change and then adjust the hands accordingly?

I wonder if you have everything back as it should? You pull the stem out to set time. Then wind it until it shift date. Put the hour hand  at 12 a clock . Wind it one more time 24 hours and see that it shift  right. With the hour hand at 12 set the minute hand over the hour  hand. Then it should work. If not there is something wrong.

Thanks for the  replies. It is as per Mr Roundel's explanation, I just can't figure out how to set the hour wheel up correctly. I think my only option is to run the movement and then hope I can trim the time down to when it changes date. Any advice greatly appreciated.

    • Here are the pics of the bridge. Looks correct, but as soon as I screw on the rotor, the watch stops. Video here: https://1drv.ms/v/s!ArG5E62RGctxjokY5ws85BzuJLVakA   Pics. Might have figured it out. I have been working on this watch for a while and since I got it as a non runner in a terrible shape, there was no guarantee that parts were proper. I think the main screw that was used on the rotor was too long, so it was stopping the main train. As soon as I fished out a much shorter and larger headed screw, things were good again. Please celebrate with me.  
    • One-dip or naphtha should be safe, but are you sure it isn't magnetized?  I would also check that.  Although, if that balance is from an Elgin 760 0r 761, I would think it would have a hairspring of non-magnetic alloy.
    • Hi, Is there a spell check function available when you are posting ? Regards CJ
    • Hi John I just did a Seiko Lord-Matic a front loader without a split stem, I used a crystal lift to remove it, although I had to have it that tight I though I was going to break the lift before the crystal would budge. So I decided that the press would be a better option as I think crystals with tension rings resist a lot of compressing. I used a crystal press to repalce it and the bezel with no issues, obviuosly a different watch to the Omega. I just took my time and kept inspecting the installation progress bit by bit Regards CJ
    • Hello All, I’m replacing the crystal in an Omega Dynamic, # 165.039, which houses a cal 552, installed through the front of the case. The replacement Sterncreuz crystal is, like the original, with tension ring. I removed the crystal using a compressed air technique to pop it out.  (I have a crystal lift, but I’m always fearful of marking the crystal edges and so avoid using it as much as possible). Now to the replacement -  any tips on putting the crystal back in?  Am I obliged to using my dreaded crystal lift to complete the task, or how about a crystal press?  I’ve put lots of crystals in using a press, but never with the movement in the watch. The thought of using one with a front-loader makes me very nervous, with the fully assembled watch sitting under the press. How would more experienced folks proceed here? Any advice, gratefully received… John Down Under…
