Digital wristwatch LCD draw
LCD watch draw: 1 µW; representative; range 0.1 µW–10 µW.
A representative 1 microwatt draw for a simple always-on digital LCD wristwatch. Movement electronics, display drive, alarms, illumination and battery losses vary by design.
Defined examples — our methodology
The marked LCD watch draw is calibrated. Unmeasured illustration details are representative.
Quartz watch
Power: 10 µW; example.
A chosen 10 µW average draw; design and functions affect consumption.
