The Apple Watch Series 2 is what the company should have put out last year: It's faster than the original, with longer battery life, a more intuitive OS, brighter screen, built-in GPS and waterproof design. If this were Apple's only new smartwatch, we would have given it an even stronger recommendation than we actually did. The problem is, the company does indeed have another wearable on offer. The Series 1, as it's called, costs a hundred dollars less and is basically last year's model, upgraded with the same dual-core processor used in the Series 2. It, too, runs watchOS 3 out of the box. As an all-purpose smartwatch, then, the experience should be similar to what you'd get on the souped-up version.
Meanwhile, though the GPS inside the Series 2 mostly matches readouts on other devices, the difference is often big enough to have big implications for estimated pace. That shouldn't be a big deal for walkers, but more serious athletes who train for events where speed matters won't want to give up their dedicated sports watches just yet. Given that, the Series 2 mostly makes sense for either swimmers or people who want distance tracking but don't care about accurate pace tracking (like we said: walkers, hikers and joggers). Everyone else, save yourself a hundred bucks and get the Series 1 instead.
