Pebble

• Core 2 Duo

  An open-source e-paper smartwatch from Core Devices, priced at $149 and based on the original Pebble design ethos. The Core 2 Duo uses a 1.26-inch black-and-white e-paper display for always-on readability and remarkable efficiency, delivering up to 30 days of battery life. It adds a speaker, a linear resonant actuator for haptics, a barometer, and a compass, and runs the open-source PebbleOS with access to a community appstore and developer tools. Its design philosophy favors simplicity, long battery life, and user control over the polish and sensor breadth of mainstream smartwatches.

• Core Time 2

  Core Devices' higher-end PebbleOS smartwatch, priced at $225, featuring a 1.5-inch color e-paper screen that keeps the platform's hallmark always-on visibility and long battery life while adding color. Like the Core 2 Duo, it runs the fully open-source PebbleOS stack — operating system, companion app, developer tools, and appstore backend — and includes hardware buttons and haptics in the classic Pebble style. The Core Time 2 targets enthusiasts who want a larger, color e-paper watch with the openness, hackability, and multi-day battery life that defined the original Pebble experience.
