Discover the $199 GPS sports watch that’s modular, repairable, and open-source.

The Una Watch has seen a price drop from its Kickstarter launch of $350 to a more wallet-friendly $199, making it a competitive option against many Garmin models. What really stands out is its modular and repairable design. It sports a 1.2-inch MIP LCD display and boasts up to 10 days of battery life, comparable to the Garmin Forerunner 70 and the Pebble Round 2 I preordered earlier this year. Unlike Pebble’s current offerings, the Una Watch comes packed with more fitness features right out of the box and embraces an open-source philosophy, including its SDK, housing, and circuit boards. Una encourages users to create their own apps, even allowing for vibe coding—users can leverage an AI coding assistant to navigate the developer documentation, generate code, troubleshoot issues, and enhance their applications.

Every component of the watch is designed to be “accessible with a standard tool,” enabling users to repair or upgrade it on their own. The open-source mechanical parts also invite creativity, allowing users to design and 3D print custom accessories or modifications, such as transforming it into a cycling computer.

On the tech side, it includes dual-frequency GPS, continuous heart rate monitoring, a barometric altimeter, a six-axis accelerometer and gyroscope, a three-axis magnetometer, and a replaceable 280mAh battery with USB-C charging. However, it’s worth noting that the Una Watch is only rated IPX5 for splash and shower resistance, meaning it’s not fully waterproof.
