IWC 3717 Case-back gasket

[PAN29824]

Hi all. Newbie here.

Picked up a used 3717 on the other forum last week and when I took it apart to clean and see what I had bought, I saw it didn't have an o-ring on the rear case-back. Any thoughts on where to pick up one?

Literally any watch parts dealer sells o ring selections for only a few dollars. There are hundreds on eBay or any auction site.

Otherwise watchbitz is a supporter here

Cool. Thanks.
