Lubrication for seconds Pivot of Tissot 781-1

[JeremyLaurenson]

What sort of lubrication should I be applying to the seconds pivot for the 781? I would assume D5... but....

By the way, thanks so much for the post,  @VWatchie - I believe the 781-1 is only a slight revision.

D5 would be too thick. I recommend a tiny amount of Moebius 9010. And, of course, 9010 for the pivot once you have mounted the train wheel bridge.

Thanks, you're welcome! I don't know what differences there might be between the 781 and 781-1 versions, but as you say it's probably just something minor.

Previously somebody was asking about the 783 which falls in the series from 781 through 784. There was one last document which I did not physically scan when I was scanning the others because I really despise scanning altogether I really have to pay attention we end up with duplicate pages etc. and then I get annoyed and start over. But fortunately your question is one piece of paper front and back so I scanned it for you. I'm attaching the PDF so now you have an answer what the differences is. Then if you need the other service information you can find it at the link below.
