Heart rate readings on your smartwatch seem wrong
The sensor on your watch probably isn't making good contact with your skin. The quickest fix is to take the watch off, clean the back, and put it on again about a finger's width higher on your wrist — the sensor needs a firm, flat contact with your skin to read your pulse. Try it on right now and do a quick test.
Your watch reads your heart rate by shining a light through your skin and measuring how much blood is flowing. If the watch is loose, dirty, or on the wrong part of your wrist, the light can't read your pulse properly. Putting it on tighter, cleaning the back, and wearing it higher on your forearm solves this for most people. If the readings are still wrong after that, the sensor itself can be damaged.

Skip — I just want a technicianCommon mistakes to avoid
- Wearing the watch too loose — the sensor needs firm contact to work
- Checking heart rate while moving or talking — the sensor needs stillness to read your pulse
- Keeping the back of the watch dirty — sweat and dirt block the sensor light
- Wearing the watch on your wrist bones instead of your forearm — the artery is higher up
Signs you need professional help
- You've tightened the band, moved it to your forearm, and held completely still, but it's still off by more than 10 beats
- The watch shows zero heart rate no matter what you do
- It worked fine before and suddenly stopped working completely
