Razer's first experiments with wearable tech had their share of problems (notably months of delays), but the company is willing to give it another shot... with a bit of a twist. Its just-launched Nabu Watch has the activity tracking, smartphone notifications and shake-to-share features of the original Nabu and Nabu X, but in a rugged sports watch design. Don't call it a smartwatch, though. While it technically fits that bill, Razer sees this more as a drop- and water-resistant chronograph that just happens to keep track of your app alerts and fitness. On the upside, that limited functionality leads to a seven-day battery life.
