Wearing Your Watch
All-day wear and exercise
For all-day wear when you’re not exercising, wear the device on your wrist horizontally, a finger’s
width below your wrist bone and lying flat, the same way you would put on a watch.
For optimized heart rate tracking, keep these tips in mind:
1.
Experiment with wearing the watch higher on your wrist during exercise. Because the blood
flow in your arm increases the farther up you go, moving the watch up a couple of inches can
improve the heart rate signal. Also, many exercises such as bike riding or weight lifting
require you to bend your wrist frequently, which is more likely to interfere with the heart rate
signal if the watch is lower on yourwrist.
2.
Do not wear your watch too tight. A tight band restricts blood flow, potentially affecting the
heart rate signal. This being said, the watch should also be slightly tighter (snug but not
constricting) during exercise than during all-day wear.
