Quartz watch vs Pacemaker average electrical draw: power comparison
The power of a quartz watch is approximately equal to the average electrical draw of a pacemaker.
ENERGY EACH SECOND
The average electrical power consumed by a quartz wristwatch during operation.
Pacemaker average electrical draw is the typical amount of electrical power consumed by an implanted cardiac pacemaker during operation.

Quartz watch
Power: 10 µW; example.
A chosen 10 µW average draw; design and functions affect consumption.
Defined examples — our methodology
The marked power is calibrated. Unmeasured illustration details are representative.
Pacemaker average electrical draw
Power: 10 µW; approximate; range 5 µW–50 µW.
A curated pacemaker average electrical draw comparison anchor. The representative value and any stated range preserve the backlog measurement convention; operating or experimental conditions can change real observations.

Why this measurement?
Why we use 10 µW
We compare the power of a quartz watch. This is an illustrative comparison value, not a claim that every example is the same.
A chosen 10 µW average draw; design and functions affect consumption.
