Both, but much more of my days are an Apple Watch SE2 than my DW5600.
I use it as a HUD - I want to know the exact time for work, current temps high/low, sunrise / sundown times, and a pop up for screening phone notifications helps me quite a bit with not checking my phone as much. I also appreciate wrist heart rate (for keeping anxiety in check,) compass is neat, and knowing the local dB is helpful for keeping my tinnitus from getting worse.
I never thought I’d like a smartwatch until I tried one.
