Speedmaster Subdials

I was asked an opinion on an early 2998 and I could not see any rings on the subdials. The seller said that this early 2998 does not have them, and on quick glance mine don't.

One of the problems was that we were communicating via this site, which does something to the images, which in the case of these rings, hides them. So it might be that on publication here, you cannot see the rings. In which case I have linked below to www.sp101.net for full images, and more of them.

However, on close inspection there are concentric circles, albeit feint:


These are hard to see - but there.
Here is another 2998 showing clearer rings:

Feint but there.

I am curious if other 2998 owners can check their collection and let me know about the state of the rings on their subdials?

Yea they just get lost in the noise by the looks, its not surprising, particularly straight on, I find they're a lot clearer at angles.
