Should I lubricate the teeth of the winding pinion?

[GPrideaux]

Today I replaced the winding pinion in my 1940s Bulova Pocketwatch. The old one was so worn that in some places it was slipping under rather than turning the crown wheel.

This wear got me thinking. I don't usually lubricate the teeth of the winding pinion, but should I? A little bit of Moebius 9504 or similar might reduce the wear on both this and the crown wheel.

It won't do any harm.

If you've ever watch Joe " The nekkid watchmaker " you’ll notice that he always adds lubrication to a few of the teeth. Its not the sort of tooth meshing that interferes with power delivery, and unlikely to spread anywhere. 

Ah just looked again at the damage, its the clutch teeth that Joe lubricates.

Is it possible to fit the crown wheel upside down on this movement. Cogs perpendicular to each other need  bevel cut to mesh together.

I always oil a couple of the teeth.
