You must have more experience and better eyes than I do! I think I see what you mean, there's no gap between the indices and what looked like the metal ring - it's just worn down.

I found a submariner style bracelet in my collection that was a close fit - it'll do until I can source something that fits even better.

Thanks for all of your help!
