The Una watch is presented as a sustainable alternative to traditional smartwatches, designed for repairability and an open ecosystem. Unlike sealed devices that often require replacement when a component fails, Una is built with a modular design, allowing users to easily replace parts like the battery or screen.

Key features include a 10-day battery life with a user-replaceable 280 mAh hard-shell battery, and universal USB-C charging. The watch focuses on core activity tracking for runs, rides, and hikes, with seamless syncing to Strava. Una also offers an open developer platform with an SDK, enabling users to build custom apps and experiences, and an accompanying mobile app for iOS and Android.

Developed in Scotland by engineers concerned with tech sustainability, Una aims to empower users with ownership and longevity, contrasting with the disposable nature of many modern wearables. The device boasts a 6-axis accelerometer, dual-frequency GPS, always-on HR monitoring, and a barometric altimeter.
