Casio has released a ring in the form of its iconic watch

The original announcement from Casio said they'd be making a ring version of the venerable DBC-611 calculator watch as well: https://www.g-central.com/casio-to-release-casio-watch-ring-...

It looks like they've instead made a ring version of the CA-53W, which - in the staggeringly few times I see someone wearing a calculator watch - is usually the one they're wearing.

I still wear a DBC-610 as my daily driver, and I do use the calculator and countdown timer features quite often.

I am glad I learned abacus method to not rely on these gimmick watches with calculators.
