Still sealed in original Rolex blister. I read somewhere that they are made out of Titanium.
Not an easy part to find and I believe that there are no after-market replacements available.
I only have a couple of them left. Once they are sold, there will be no more...
Face-to-face transactions in Western MA are encouraged. Otherwise, fully insured shipping within the U.S. would be $8.
For overseas buyers, shipping will be at cost and I would be happy to let the buyer choose the shipping method.
3 day return policy if the part that you purchase is not as described. Shipping fees are not refundable and the valve would have to be returned in the same SEALED packaging as received. (Once the original Rolex packaging has been opened, the sale is final...)
