Valjoux 23/72 Oil Chart

[Negot8or]

Hi.  Does anyone have an oil chart for a Valjoux 23/72?

Thanks!

Any oil chart that may exist for those calibers would say "fine watch oil" or "grease" for the relevant points.

Thanks, nickelsilver. What's the implication of that?

I've seen some for other "old" Valjoux movements... so I was hopeful.

Just that "tech guides" for many old watches amount to a parts list, and when they were really motivated they'd say fine oil here and there and grease here and there. The Valjoux 23/72 family is pretty old, so...

Oil the train, grease the high friction points, like you learned in school right? (haha) When these watches were made nobody imagined they would be serviced by a nonpro. Now we have tech guides that tell you to use 8 different oils and pitch certain parts because you can't oil them like the factory does.

These Valjoux calibers are tractors. Moebius 9010 on balance pivots, 9415 on pallet jewels, pretty much whatever Moebius oil on the rest of the train. Grease the winding and chrono functions, and when these were made a lot of guys would have used Moebius 8300 or Vaseline for that. That's about it. It's not a Frederic Piguet where 9020 where Jismaa 124 is needed will result in disaster- it's a real watch.

Tractors! Yes in a sence but the 72C is one of my absolute favorites. 
I made a compilation of how one could lubricate this beaty out of some old service instructions.
The rest of the watch one can service as an ordinary movemment just as @nickelsilversaid.
