I'll bet the central gold ring moves; I think it may be a solstice calculator or somesuch (JASOND being the initial letters of the last six months)

I bet the other side of it says JFMAMJ

[THECORBYLOON]

Stews, do you own an antique shop? :)

[stewey]

THECORBYLOON, You got it; however the best answer goes to society for the humor:)

Looking back, Corbyloon really didn't answer "What is the name of this thing". It's called an Aquitaine ring. Anyway, he was close enough.
