The Garmin Instinct 2 Solar is a rugged outdoor GPS smartwatch built to US MIL-STD-810 durability standards, aimed at hikers, campers and outdoor users who want a tough, simple watch with exceptional battery life rather than a data-dense running or triathlon computer. It has a 45mm case with a monochrome, always-on transflective MIP display at 176 x 176px protected by Garmin's Power Glass solar-charging lens, wrist heart rate, Pulse Ox, and a broad set of outdoor and fitness tracking modes, finished in this Mist Grey colourway. It is rated 10 ATM water resistant and built with a fibre-reinforced polymer case and stainless-steel bezel. Battery life is the headline feature: up to 28 days in smartwatch mode without solar, extending toward unlimited battery life with sufficient daily sunlight (Garmin quotes around 3 hours per day at 50,000 lux for indefinite runtime), and up to 30 hours in standard GPS mode, extended further outdoors by the solar lens. This is a meaningful upgrade over the standard (non-solar) Instinct 2 in this catalogue for anyone spending long, sunny days outdoors between charges.
