Band and charging

Strap fit and care

Where to wear it, how tight, and how to keep it fresh.

1. 01

   Position

   One finger-width above the wrist bone, snug enough that it does not slide when you rotate your wrist.

2. 02

   At night

   Slightly looser than daytime. A band that leaves a mark is too tight and will produce noisier readings.

3. 03

   Cleaning

   Rinse the knit strap in cool water weekly and air-dry. No soap, no machine, no direct sun.
