Lubricants?

G Grimbergen

Hello,

This is my first post. I was considering using Krytox for the lubrication of watch movements (seagull 1901). The idea is very attractive, as within my watch rotation probably the lubrication would last a lifetime (comparing synthetic oils with Kritox is like comparing a bike with a space shuttle).

Maybe the oil would spread and damage the movement. Has anyone tried this? I'm thinking in Krytox 103 instead of moebius 9010 and 9415, Krytox 106 instead of moebius HP1300 and Krytox 205 instead of moebius 9504, 9501 and 9415 (lubricants taken from ETA 6497). I do have ample supply of Krytox 105 oil and 205 grease, both with stellar performance compared to synthetic oils.

Removing these lubricants is very difficult, as fluorinated solvents must be used, and cleaning afterwards would be likely impossible. This would be a one time lubrication, and if any issue arises, the movement would have to be replaced by a new one. As these oils are that good, any swarf, dust or impurities within the oil should not affect its performance.

Maybe I will try it, maybe not (probably not), but has anyone tried using fluorinated lubricants in watch movements? I would especially appreciate Archer opinion on this. If the movement worked for one week, I'm confident it would work without maintenance for 25 years. Probably it would not even work at all.
