Hello cherylfromsutter creek,
Yes, Apple Watch is capable of tracking Sleep Cycles (Awake, REM, Core, Deep), total time asleep, respiratory rate, and heart rate.
- Track your sleep with Apple Watch - Apple Support
- Track your sleep on Apple Watch and use Sleep on iPhone - Apple Support
I hope this helps!
