apple watch downtime

My apple watch series 8 (V. 9.2) goes into downtime everyday at 10PM and goes off at some point in the morning (I believe 8 but as of this question being written i’m on vacation so i haven’t gotten up before 8 to confirm this). My phone does not have downtime enabled (at all), and I turned off all my scheduled do not disturbs that I have set up for during the week. Why does my watch still go into downtime, and how do I fix this so I can use my watch after 10PM?
