I do similar, bed around 10pm and sleep until I wake naturally. I have my watch alarm set for 7:30am (just in case), but haven't needed it for months. I just wake up when my body is ready, usually around 5:30am. Not having an alarm jolting me awake and letting my body wake at the right time in my sleep cycle has made a big difference to the energy I have, especially at the start of the day. I hit the office at 6:30am, couple of golden hours to go deep without the phone ringing... and home every evening on time.
