Digital wristwatch LCD draw
Digital wristwatch LCD draw is the electrical power required to operate the display of a basic digital wristwatch continuously.
How big is it?
1 µW of power
LCD watch draw · representative
Typical recorded range: 0.1 µW to 10 µW.
A little perspective
Quartz watch is about 10 times larger on this measurement.
