Una Launches Modular, Repairable GPS Watch for $249

Scottish startup Una has launched a modular and repairable GPS watch priced at $249, aiming to disrupt the wearable technology market with sustainability and open-source design. Founded by Lewis Allison, former CTO of Shot Scope, the company promises a device built for longevity—but with some trade-offs.

Una Launches Modular GPS Watch

Scottish startup Una has introduced a $249 GPS watch designed to be modular, repairable, and open-source. Founded by Lewis Allison, former CTO of golf watch company Shot Scope, Una positions its product as a sustainable alternative to traditional smartwatches. The company’s slogan, "one watch for life," underscores its commitment to longevity and user-driven repairs.

The Una watch features a 1.2-inch Memory In Pixel LCD display with 240 x 240 resolution, a Cortex-M33 microcontroller, 2.5MB of RAM, and 4GB of eMMC storage. It runs FreeRTOS, an open-source operating system designed for embedded systems, and is powered by a battery expected to last 7–10 days with 20 hours of GPS performance.

Una has made replacement parts available, including displays for $50 and batteries for $40. The watch is IPX5-rated, meaning it can withstand rain and sweat but is not fully waterproof. The USB-C port, however, carries an IP68 rating for better protection.

The company has released its software, housing, and circuit board designs on GitHub, inviting community collaboration and customization. While this open-source approach is novel, the watch’s functionality and durability lag behind established competitors like Garmin and Suunto. According to Engadget, the Una watch received a rating of 7.8 out of 10, with praise for its repairability but criticism for its limited features and ruggedness.

Why Modularity Matters in Wearables

Modular and repairable devices are gaining traction as consumers and regulators push for more sustainable technology. Companies like Fairphone and Framework have pioneered this approach in smartphones and laptops, respectively, by offering devices designed for longevity and user repairs. Una’s entry into this space with a GPS watch reflects a growing trend toward reducing electronic waste and empowering users to maintain their devices independently.

However, modularity often comes with trade-offs. For instance, the Una watch’s design prioritizes repairability over ruggedness, making it less suitable for extreme conditions like muddy trails or water immersion. This balance between sustainability and durability is a challenge for startups aiming to disrupt established players in the wearable market.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

Una’s launch is a bold experiment in merging sustainability with wearable technology. For founders and operators, it highlights two key insights: first, there’s a growing appetite for products that prioritize repairability and open-source collaboration, even in niche markets like GPS watches. Second, modularity isn’t a silver bullet—it introduces design compromises that may limit the product’s appeal to hardcore users, such as athletes or outdoor enthusiasts.

The Una watch’s open-source approach could also foster a community of developers and tinkerers, potentially accelerating innovation. However, startups must weigh this against the risk of fragmentation or a less polished user experience. For now, Una’s watch is a promising first step, but its long-term success will depend on whether it can bridge the gap between sustainability and performance.
