All-day Wear and Exercise
Wearing Your Watch
- 3 -
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.
