What hackers pick instead
- Pebble Time 2Recommended as an open-source smartwatch with tactile buttons, always-on sunlight-readable display and long battery life. Critics note broken screens and smartphone dependence.53recommend
- Pebble Round 2Recommended for a thin, stylish smartwatch with weeks of battery life and a simple button-driven interface; the main caveat is the 30-day manufacturing warranty.38recommend
- Pebble 2 DuoRecommended for its readable display, long battery life and open third-party apps. The most common caveat is rubber buttons that crack or fail, plus shipping delays.17recommend
- SQFMI WatchyOpen, hackable e-paper smartwatch that you can program yourself, with reliable timekeeping. The most common caveat is that it is bulkier than expected and not built for daily wear.6recommend
