A question on Panerai crown seal

[Bruce]

I bought a new PVD crown (from Tourby) because my original crown literally broke off at the base of the spring holder. When I went to install the new crown I discovered that the seal for the crown was broken and curled back on itself between the crown and the case. The original watch came from DSN, and I find that I wear it alot; I like the flat PVD that David has. I would like to reinstall a proper seal but do not know what size to look for. I have re-assembled the watch for now but am afraid water will eventually work it's way into the beautiful 6497 swiss movement this watch has. Any help with correct seal size(s) would be greatly appreciated.

Here is what things looked like after dis-assembly:

This is after re-assembly (with no seal):

They pop up at ebay from time to time, but as a collection of 50+ different sizes o-ring seals rather than one or few. Even so, at the price they go for (50+ for some $10) they're worth every dollar.

Keep an eye on the 'bay' every so often
