This series now has an always-on display and for the first time, cases are made of 100% recycled aluminum.
You no longer need to raise your wrist or touch the screen to see the time because the display never sleeps.
So whether you are riding a bike, cranking out some crunches or counting the minutes in a meeting, all you need to do is glance to find the time or your workout metrics right there where you want them.
The display dims when your wrist is down, yet key features, like watch hands, remain visible at all times.
The Apple Watch case is made from 7000 series aerospace-grade aluminum that is lightweight, beautiful, and now 100% recycled — culled from the iPhone XR production process.
A new low-power driver, ultra-efficient power management and a new ambient light sensor work together so the display can stay always on with up to 18 hours of battery life.
I have the Apple 3 series - its waterproof, battery lasts long enough not to ever be a problem.
The only problem is it never records my heart rate when I run ( i don't use a heart rate monitor band). I can see it live while i'm running, but when i download the file to see my per km splits its always blank. Anyone else have that problem?
