Una GPS smart watch – Repairable, USB-C charging, developer-friendly
Points and comments are a snapshot, not live.
A modular, repairable GPS watch with USB-C charging and an open SDK.
UNA is a GPS watch built for repairability and sustainability. It features a replaceable 280 mAh battery, USB-C charging, dual-frequency GPS, an always-on heart rate monitor, barometric altimeter, 6-axis accelerometer, and a 10-day battery life. The watch is fully modular, allowing users to replace components like the screen or battery with a single screwdriver. It offers an open developer platform with an SDK for building custom apps and syncs with Strava via a mobile app for iOS and Android. The watch is IPX5 rated (splash and showerproof) and non-submersible.
What commenters are saying
Commenters reacted with strong skepticism to the IPX5 water resistance rating, calling it a dealbreaker for a watch. Many noted that Garmin and Apple watches offer IP68 or better and questioned how a 'designed for life' watch could lack water resistance. A minority praised the USB-C charging and repairability, but the lack of spare parts on the website was also criticized. One commenter pointed out the phrasing is deceptive: the cable is IP68, but the watch is only IPX5.
Another camp focused on battery life: Garmin Instinct 2 users reported over a month between charges, making UNA's 10-day claim less compelling. Some noted that open devices often miss key use cases, and that water resistance seals degrade over time anyway.
