Like many other early Android Wear pioneers, ASUS thought that it was hip to be square. It made sense, since smartphones have square displays too, not to mention the (then) scarcity of truly-round displays. ASUS trimmed the price to make the Zenwatch cheaper than its rivals, and curved the glass over the face to offer an illusion of greater ergonomics. The end result is a watch that made square faces look reasonably stylish, even if it would only ever cater to a niche.

Two years down the road and ASUS has firmly grasped a copy of the fashion watch design playbook and is holding it firmly with both hands. The Zenwatch 3 is packing a rose-gold inlay, a chunky crown and double pushers, making it look less like an Android Wear device and more like a Longines. It's the sort of watch that goes down well with business types who want to be seen wearing their money on their wrists.
