This listing is for 2 pieces of a .7mm aftermarket bezel gasket made for the Seiko SKX007 family of divers as well as the new Seiko 5 Sports SRPD or "5KX" models. 

We are professional watch modifiers which is why we have these parts. Check out our eBay store :)

Please feel free to contact me with questions. I'm glad to help and thank you for looking.
