No harm in asking.

As shown in the photo below, the Enicar Sherpa Dive should have a ~31mm red ring that fits inside the bezel. It rotates and has a triangular pointer with a small hole. Please let me know if you have or see a spare. Many thanks. -Dan

 

Fun watches these Enicar Divers. Good luck in your hunt!

 

Dan you can also use the Bezel of the Aqua Graph. On Ebay you can often find some repros for them.
Good Luck!

 

Thanks Nico, I will keep looking. I often see rings for the Sherpa Guide, but they are too large.
