    Cleaning and Lube crown screw?

    I was wondering if we should clean and Lube the screw in crown from time to time?

    Sometimes it looks a bit dark and I used a tissue paper to clean up some of the 'dirt'. The paper does show some dirt which I'm not sure if it's just small metal from the screwing in and out or a lube that is used.

    I was wondering if I should put something like a grease (teflon grease or sillicon greas) or oil in the treads?

    Any tips is appreciated to help make the watch last longer.

    While your concern may be warranted, I wouldn't do anything without consulting Sinn first.

    I was told by a local Sinn Authorized reseller to apply a 'mild silicon based grease' if needed.

    You could try flossing the threads with waxed dental floss but be very careful if you give it a go as there was thread on WUS not long back and the poor guy had had got floss in his crown (sounds painful) and was looking at a trip to the watchmaker to put matters right. Just for info, I’ve got all sorts of gunk in my threads and so long as they work well they don’t get cleaned.

    Yeah, I think a careful cleaning is fine. Then a tiny drop of silicon would be ok too. But if it ain’t broke, don’t fix it.
    Too many flipped...

    +1 on the waxed floss trick (and the part about being carful). Has massively improved gritty threads for me in the past.
