5th generation of the Apple Watch and it still doesn't come close to replacing my Pebble, unfortunately. At least it's closer to an actual watch now, with an always-on screen, but it still can't last 24 hours on a charge.
Does Pebble have a sim? The biggest benefit of apple watch for me is that I can take it anywhere without my phone, play sports, shopping, running, the sim card in the phone is the best thing that keeps me away from staring at my phone screen while I am going out.
Still, I found my Pebble greatly reduced the time I spent looking at my phone because I didn't need to take my phone out of my pocket upon receiving a notification or to check the next item on my calendar.
