There is a watch-shaped ring around my left wrist, a permanent tan-line. I've worn a watch since I was a kid. I've always liked to sleep with my watch. To shower with my watch. To swim with my watch. Not everyone likes to do this.

The new Apple Watch is faster; has a far better OS; onboard GPS; a brighter display and is waterproof to 50 meters in salt or fresh water

Same battery life, mostly; GPS activity causes a big hit on battery life for running; Lacks always-on display; A tad thicker and heavier; Requires an iPhone to work

The Series 2 is simply what the Series 1 should have been. It has been improved in nearly every way and is finally an all-in-one legitimate fitness tracker with the addition of GPS and water resistance (it should be noted, though, that the new Apple Watch cannot measure elevation, so climbers...

GPS; waterproofing; S2 dual-core processor

Wrist raise still not fixed; doesn't track elevation; increased size and weight

In many industries, but especially in technology, there's a common wisdom about waiting for the second or third iteration of a product before purchasing it. This is based on the idea that the first version of a product will often be the most flawed or compromised - a product still trying to find its...

The Apple Watch 2 was a while coming. The constantly evolving

The Apple Watch Series 2 is the best smartwatch-fitness tracker hybrid we've seen, and better than the original watch thanks to a brighter screen, faster performance, and a waterproof design.

Built-in GPS; Waterproof to 164 feet; Brighter screen and faster performance than original Apple Watch; Accurate fitness tracking; Plenty of third-party apps

Expensive; Battery life has not improved from predecessor; Lacks integrated sleep tracking and continuous heart rate monitoring when not working out

The Series 2 (and Series 1) is in no way worse than Apple's last version, and it serves its purpose with aplomb. It's still the best smart watch choice for iPhone owners, and that's unlikely to change any time soon.Don't write off the Series 1 either, though.

Using an Apple Watch during the past 16 months was a mixed experience: one that saw Apple's first wearable launch amid high praise, confusion, and skepticism of just how much a tiny wrist-worn computer should be able to do.

Finally; fast and reliable performance; Screen is easier to view; even in the sun; Built-in GPS; Water resistance is a nice feature for anyone to have

Battery life is still a day; two at most for non GPS users

It's been a while coming. The constantly evolving iPhone and iPad line-up has taught us to expect Apple products to be updated on a yearly basis, but the first-gen Apple Watch was on the market for 16 months before Apple delivered its successor.

Equipped with a noticeably faster dual-core S2 processor, its own standalone GPS radio, and now with a waterproof design, the Apple Watch Series 2 is a worthwhile and fantastic upgrade from the first-generation model. It's also a great jumping on point for new buyers.

Still the best smartwatch around…; … and now one of the sportiest; Beautifully made and very customisable with straps and faces; Longer-lasting battery;

Many rivals sport/smart watches still last longer; Overkill if all you’re after is wristy notifications;
