My husband‘s work is finally allowing him to wear a smart watch. Long story.

For years he has wanted one so that he can track his health stuff but mainly, his sleep. The past three nights that he has had this watch, this is what he’s been getting:

My watch (series 8 45mm SS) gets this information:

(The last two days for me I had to input the information manually because I fell asleep before putting my watch back on from charging it 😩)

Is there something he needs to specifically do for the Ultra 2 to track his REM, deep, etc. sleep? He set up his stuff in the watch and health apps the same way I have.

Thanks in advance!
