But i's not a perpetual calendar, so it will need to be adjusted every other month-end or so.

Anyway, I pull out the crown to conserve power when I'm not wearing it because the capacitor has already deteriorated and doesn't hold much charge anymore.

Hmm, maybe!

It's actually quite hard to turn the bezel. Some people even think it doesn't turn because the friction is very high. 

I use the bezel to time things all the time. Like baking times, bus arrival times, etc. I do love timing bezels. 

Casio has a lot of cool watches in their back catalog. I really like their "game" watches and I wish they'd rerelease those.

It's the hinge for the chrono pusher. BTW, the left crown operates the internal slide rule.
