What is crown size of SS sub rep?

[rolexconfuse]

I need to get a replacement SS crown for my sub rep and I'm wondering what the crown size is on the Sub.

I've got a link to a bunch of screw down crowns but I'm not sure which is the right one, can someone tell me which one is the correct size?

The rep crown for a rep sub is 7mm. And what you need is another 7mm rep crown- hopefully one that fits your existing case tube on your sub. I could send you an extra crown, but there are no guarantees it will fit your case tube. You could PM me (hopefully you're in CONUS or Canada). There is a guy in Hong Kong that sells the crown and tube and they are rep, not authentic- but you'd have a set. Then you'd have to swap them over, or have a watchsmith do it for you.
