Lubrication of Automatic Winding Mechanism Clutch in Hamilton 662

[JLipinski]

I have a Hamilton 662 which uses the clutch mechanism (pictured below) to transmit torque from the automatic winding rotor in one direction and disengages the rotor when the crown is turned. I haven't seen something like this before, so I'm curious what the proper way to lubricate this would be and if there is a name for this type of mechanism that's typically used. There is an undercut on the internal recess, allowing the spring and pivot with pinion to be slid into place. These images, excepting last one of all three parts disassembled were taken during disassembly, so take the volume and consistency of visible oil with a grain of salt.

Moebius 9010 on the internal surfaces of the recess?
Lubeta V105 the whole thing? That doesn't seem right, since only the internal surfaces are friction points, no need to lubricate the teeth of the wheel. V105 the pinion and spring then assemble into the wheel?

Would like to hear your thoughts on this.

An update including some investigation into this specific caliber.

This assembly seems to be identified as a 'Coupling Clutch'. Information on the 662 is sparse, but thanks to this post at hamiltonchronicles, it appears that the 662 is essentially the 661 with the addition of the date complication. Luckily more information is available on the 661, ranfft indicates that it is based on the Certina 25-45 (or is it Kurth Frères). Which vintagecertinas has parts lists for, thankfully. This identified the assembly as Certina part 25-45 1520 which is readily available as new old stock, and labeled 'Coupling Clutch' in most of those listings. So that's one part of the mystery solved.

Unfortunately, the question about lubrication was asked back in 2016 by sstakoff who was also puzzled regarding best practice. I've scoured the web for 25-45, 25-451 info or service videos, but so far haven't found anything regarding technical manuals or what people have used in servicing. Seems that Hamilton service bulletins 207 and 207A cover these calibers manufactured for Hamilton. These are available from the NAWCC library, so I think I'll use this excuse to become a member. With any luck, they have lubrication details in those.
