Smartwatch heart rate monitor not reading or showing dashes
A smartwatch heart rate monitor needs direct contact with your skin and takes a few seconds to read. Make sure the watch is snug on your wrist, the back sensor is clean, and you are wearing it directly on your skin with no clothes or sunscreen in the way. This fixes it in seconds for most people.
The heart rate sensor on your watch needs skin contact, moisture, and proper positioning to work. A loose watch, a dirty sensor, wearing it over a sleeve, or having sunscreen or lotion on your wrist can all cause it to fail. We will check the fit, clean the sensor, and make sure you are wearing it correctly.

Skip — I just want a technicianCommon mistakes to avoid
- Wearing the watch too high on the arm instead of on the wrist bone. the sensor needs to be over blood vessels
- Having lotion or sunscreen on the wrist that blocks the sensor
