Q: Do I have to wear my ReadiWatch 24 hours a day for it to have accurate sleep readings?

A: No, ReadiWatch does not require that you wear your ReadiWatch 24 hours a day for it to have accurate sleep readings.

Q: Can I spend most of the day without my ReadiWatch on and then wear it just to track my sleep?

A: In general, yes. While wearing your ReadiWatch during your wakeful hours has many benefits (such as Fatigue Alerts and fitness features), ReadiWatch does not require that you wear your device during wakeful hours for accurate sleep tracking.

However, for optimal sleep readings, you must put on your ReadiWatch 5 - 10 minutes before you go to bed, ideally when still moving around. Similarly, it is recommended that you wear your ReadiWatch for 10-15 minutes after waking up for ideal sleep accuracy.
