Another clarification, the display of the Bip(and Pebble, Garmin and others) is not a transreflective type but a SHARP Memory LCD where pixels only need power to change their state but need almost no power keeping their current state, like e-ink, but better, so it looks like transreflective in the sunlight.

The transreflective LCD type of the Gameboy would absolutely nuke your battery life as it needs to be actively refreshed even on stationary images.

I'm deeply saddened this type of display is not more popular among wearables vs OLED. Who doesn't want 30 day+ battery life and always-on sunlight visibility?
