Apple Watch Battery Life

Apple is very big on their all day battery life, but with the advent of the forty five millimeters, series seven that iy got this fall, it got me wondering. The screen on that watch is almost identical in a lot of contexts, other than for things like seeing the second hand tacking across,. Half the time, i can't even tell if it's down or up. And essentially can figure it in a few ways to say, hey, what really matters to me right now is battery life. I woud care about battery life like it can last a very long time.
