I'm going to order a few items from ofrei and I'm thinking of picking up a few crown gaskets. I'm new to the amateur Rolex business so I'm not too sure if there is one or 2 sealing gaskets. I do not see a gasket on the inside of the crown right now. I do see some green corrosion on the inside of the crown of which concerns me slightly because theoretically nothing in that area should be copper plated. The crown should be solid gold and the case stainless so I'm not sure what the story with the greening is. In any event, can you guys point me in the right direction on the gaskets?? Thanks guys.

The crown is a gold cap on brass plug and the tube is steel you have one O'ring in the tube and one flat gasket inside the crown the green is corrosion from body skin acid and will eventually lock the tube and crown together if not cleaned properly. Hope that helps. Rikki

The green corrosion could be from nickel in steel. Nickel content in 904L steel is about 25 %
