For fans of e-paper tech, the iconic Pebble brand has returned. The Pebble Round 2 smartwatch launched today, staying true to its roots of simplicity.

Featuring a 1.3-inch color e-paper display, the new watch solves the biggest complaint of modern wearables: battery life. Pebble claims it can last up to 30 days on a single charge. It eschews complex app ecosystems for focused health tracking, notifications, and quick replies, appealing to users tired of constant distraction.

At a time when smartwatches are becoming wrist-computers, the Pebble Round 2 bets on "calm technology."
