It doesn't have a fancy metal case, built-in cell connection, or other unnecessary add-ons. What the Pebble 2 Smartwatch does have is a solid mix of features and value. Like most wearables, it does activity and sleep tracking, leveraging the built-in heart rate monitor for added accuracy. It also displays notifications, keeps a timeline for an at-a-glance look at your day, and provides access to a rich ecosystem of apps. But unlike most smartwatches, it can run for up to seven days on a single charge, is water resistant to 30 meters, and has an ePaper display that's always on, so you're never wearing a blank black box on your wrist.
