Most of those features got rolled out to previous Apple Watch units as well, as I outlined here. But in reality, most of the new features actually came with watchOS 4, which was introduced at the same time. It also gains an altimeter, for better tracking of elevation. What it gains though in ‘GPS+Cellular’ edition is…well…cellular service (and the associated magical red dot). In theory, it’s got the same heart rate sensor, as well as the same GPS capabilities. Of course, in many ways the Apple Watch Series 3 isn’t appreciably different for sports usage than the previous Apple Watch Series 2 unit. Of course, I’ll briefly touch on those things below, but my focus here is how well this performs while working out or racing. This review is all about sport and fitness, since there’s a gazillion other places you can read about general stuff like looking at the pretty apps screen above. Over the last 6 weeks I’ve been wearing the Apple Watch Series 3 Cellular edition to see how well it works not just in daily use, but more importantly sport and fitness use.
