4. Avoid prolonged submersion — daily splashes and rain are fine, but swimming, hot baths, or sauna sessions are not recommended.

If you are between sizes, select the larger size for the most comfortable fit, especially for the index finger where the ring performs best.

This feature works through the ring's built-in acceleration sensor (DA267) in combination with the companion app.
