A modular smartwatch designed for user repairability and long battery life is now available directly from its manufacturer. Priced at £240, the UNA Watch can be ordered immediately, with international customers advised to review revised shipping policies that include additional delivery charges calculated according to the destination country.

A Design Built for User Repair

The device’s construction reflects a shift toward sustainable electronics, eschewing proprietary fasteners in favor of standard screws. This deliberate design choice allows owners to open the chassis for self-service repairs. Crucially, the modular approach extends beyond routine battery maintenance, enabling components like the screen to be swapped out entirely. This paves the way for potential hardware upgrades rather than full device replacement if a single module fails or becomes obsolete.

Core Hardware and Energy Efficiency

At the heart of the wearable sits the UNA Core module, powered by an ARM Cortex-M33 microcontroller unit with 4 GB of eMMC storage, running a fork of the FreeRTOS real-time operating system. Visuals are rendered on a 1.2-inch MIP display with a resolution of 240 x 240 pixels. The memory-in-pixel panel uses LED backlighting but relies primarily on ambient light, providing strong readability in direct sunlight while conserving energy. A 280 mAh battery supplies the watch, delivering a minimum of 10 days of operation on a single charge.

Fitness Tracking and Important Limitations

The UNA Watch features an extensive sensor suite to support outdoor navigation and fitness training. It includes a dual-band GNSS module for precise location tracking, along with an accelerometer and a barometer. Optical heart rate monitoring provides data on workout intensity to help users evaluate training effectiveness, and the platform supports full Strava synchronization. While the device complies with the IPX5 water resistance standard for protection against water jets, the company explicitly clarifies that the watch is not designed to withstand submersion and should not be used for swimming.
