Do I oil the interface on these reverser wheels on a Bulova automatic 11ALACD?

Im working on this vintage 11ALACD. The diagram for the automatic mechanism is below. Do I oil the interface of the reverser wheels circled below? I read somewhere that I should treat the reverser wheels with epilame but I am not sure that applies here.

Yes.

Next question is what sort of oil to use.

There are a couple of Bulova service manuals around for similar watches. The first one also gives some information on checking the tension spring, but neither tell you what oil to use.

This shows what happens if you don’t oil them

Let me know how you get on. I have one of these in my project box waiting attention.

I would lubricate with a tiny bit of Moebius 9501. I am sure others will have other preferred lubricants but thats what I would use.

Seems my options for this application are KT22 grease or 9104 in my possession. Would you guys say one is better?

Also I already treated the reverser wheels with epilame. Doesn’t that mean the oil won’t spread over the teeth?

Between the 2 I’d choose 9104.
