THE LUBRICATION INSTRUCTIONS FOR A GENTS WRISTWATCH ACCORDING TO BRITTEN'S HOROLOGICAL ENCYCLOPEDIA. NOTE THE ABSENCE OF INSTRUCTIONS TO OIL WHEEL TEETH AND PINIONS AND THE SPECIFIC INSTRUCTION TO USE FIXATIVE TO PREVENT TRAIN CONTAMINATION.
GOOD LUCK WITH YOUR WATCHES.
For an average size jewelled gents wrist watch movement
Mainspring- Mainspring grease
Barrel arbor- Pressure resistant oil
Centre wheel pivots- light clock oil
Third wheel pivots- Fine watch oil
Forth wheel pivots- Fine watch oil
Escape wheel pivots- Fine watch oil
Pallet arbor pivots- Fine watch oil
Balance pivots- Fine watch oil
Pallet stones- Fine watch oil
Before oiling dip escape wheel, pallets, cap jewels, shock proof jewelling, and sweep wheels in a surface fixative, this keeps oil from spreading and contaminating the train and balance assembly.
Crown wheel- Pressure resistant oil
Click- Fine watch oil
Stem pilot, square- Fine watch oil, bearing- Thick grease
Clutch wheel and winding pinion ratchet teeth- Thick grease
Yoke pivot- Pressure resistant oil
Yoke/setting lever friction surfaces- Thick grease
"huff", Greg. My comments about applying a TINY bit of oil to a watch movement's gear teeth, are based upon MY personal experience and I would not be recommending this if I had found that it caused problems. I note in your quoted lubrication instructions that it says "Pallet stones- Fine watch oil" which indicates that it is appreciated how sensitive this area is to contact friction and that there is a need to minimizing it in order to ensure accurate timekeeping. That "fine oil" works by eventually getting distributed to all of the escape wheel teeth.
My point is that ALL of the OTHER intermeshing tooth surfaces in a mechanical watch movement will ALSO benefit from this treatment to reduce friction and wear there.
For example, only a few years ago I needed to service a favorite automatic watch that I wore every day for the prior 3 years which had been running continuously for that time. I was the original owner of the watch when it was new and it had a Miyota Automatic movement that, after careful regulation, kept near perfect time. I was thrilled to have a mechanical watch keeping quartz watch accuracy. Suddenly, one day it began to lose about ten seconds per day. About three days after that, it stopped and would only run sporatically if shaken. Then it would not run at all even though it was fully wound!
After cleaning the movement and lubricating it, including the gear teeth, it ran strongly again (TOO strongly, unfortunately, because, during the cleaning, I had accidently damaged the hairspring!). I then placed the cleaning fluid into a white tea cup and let it sit there for several hours. Sure enough, a fine silvery grey "silt" collected at the bottom of the cup. From past experience, I knew that if examined under a microscope it would consist of MICRON sized steel particles! There's only ONE place they could have come from...the side tooth surfaces of my watch's gears. Most likely, the teeth were not lubricated at the factory and as a result the watch only ran for 3 short years before friction caused by the accumulated grit between the gear teeth rendered it unusable. IF they had lubed the teeth a bit at the factory, then it probably would not have needed to be serviced and I might still be wearing that watch today.
