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 your wrist.
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.
