An English Service Manual for the Omega 860/861/910/930 movements
These scans are made from an Original service manual that I own.
Clicking on any of the small pages below, will open up a new browser window containing a larger ( 50 - 80 KB ) version.
This service manual will probably also cover the 911 movement, which became available AFTER this was published. The 911 movement is basically a 910, where the 24 hr indicator has been relaced with a constant second hand.
I don't think Omega will have a problem with me reproducing these pages on the internet. They are good enough quality that they can be used, but not so good that people can copy, print & sell them as originals.
I have written this page to share the limited knowledge & information I have. Please don't abuse me, my work or other peoples pictures. It's not a nice thing to do !
Finally, It pisses me off that I have to write a disclaimer like this !
