A lot more than that. 2ma
Smaller packages may be more efficient.
Analog circuits are weird though

2mA minimum, and that’s just q current. It’s gonna be much higher when you’re actually using it for a clock.
I’m sure the casio’s main power sink is the display. I bet the refresh rate could be reduced for better battery life.

Isnt the refresh rate just 1 Hz?

Yep.
