Size of the red sherpa guide ring

I’m not at home now or I would measure one for you. Here’s one for sale with a “measurement”:


Caveat: I’m always suspicious of measurements that are exactly a whole number — seems wildly unlikely.

There are at least two different designs of indicator rings and how they mesh with the crystal and the bezel. The one in the auction is a later design. I’m not up on the exact differences. Hopefully someone who is will chime in.

No, different size. Thanks for posting though as I'm back and had forgotten.

I have two spare Guide pointer rings. Both are the later style with a "house" pointer and a "stepped" outer edge. I believe earlier pointers have a bevelled outer edge instead. When the retaining method changed, I do not know. I also do not know if it was done at the same time as when the pointer was changed from triangular to house style. While I have watches with the earlier rings, I'm not wildly excited about taking them apart just to measure. They are fragile after all.

I know one of the spare rings I have is aftermarket production, perhaps even both. They are different. They are fragile and precise measurements with a caliper are not easily done. Here's what I have:

inner diameter / outer stepped diameter / outer diameter

34 / 34.9 / 35.4

34 / 35.8 / 36.4

I see, yes mine is smaller at 30.9 / 32.2 / 33.4
You don't happen to know where I can find a bezel ring or insert for my Aqua graph, would you?

Outer bezels for aqua-graphs and jet-graphs are very hard to find. Occasionally they turn up on ebay but they are usually in poor condition.
