oooooh, that "special oil"....woo hoo!:think: :-( :roll:Their own special oil, and the usual engraved rotor. Nothing else.
You may think little of the special oil, but I had an intersting discussion with Lothar Schmidt about it, and it not only simplifies service, it is also purer than the standard oil ETA uses. This is important concerning what remains of the lubricant in the movement to do damage once the oil dries out over time.oooooh, that "special oil"....woo hoo!:think: :-( :roll:
You know, now that I think it through, I've got no room to jest; I've been a firm believer in "full synthetic" motor oils in my vehicles for years...I s'pose the same basic principles apply here as well...thanks for making me use my brain for a rare moment or two!:-! :thanksYou may think little of the special oil, but I had an intersting discussion with Lothar Schmidt about it, and it not only simplifies service, it is also purer than the standard oil ETA uses.

Perhaps there will be comparative pictures of the special oil and the standard ETA oil in the next catalog - I suggested as much to Mr. Schmidt.
Not´to mention that the special oil increases the temperetaure range in which the watch will be less affected.
I'd guess that they make the movements with perfectly good oils; but with Lothar's nose for innovation, he found something a little better. In my example above; everyone from Ford to Mercedes sell their new cars with perfectly good motor oil, but there is better available in full synthetics....
As far as I understand, the problem is that ETA recommends sevearl oils for different parts of the movement, thus opening the possibility for incorrect servicing. Sinn use the same hi-grade oil throughout, with extra purity. I guess in terms of workshop logistsics, the Sinn way has advantages - in addition to the greater temp. range.
