14060 would have the white gold surrounding the pip. Apparently the seller didn't know what he had. That said I'm not convinced it's the service replacement for 5508 if there is one. It looks like the regular service replacement for old subs. The difference in the outer diameter between 5508 vs 5513 is about .2 mm if my memory is correct. Too small to b noticeable. Nowadays most watch makers would just fabricate the regular insert to fit the 5508 bezel.
Nice 5508 btw. [emoji122]
I blame it on the autoconnect.
