With this ultra-performance GPS multisport smartwatch, you can reach goals beyond the 100 km mark. Cutting-edge solar technology, an energy-efficient processor, and a more powerful battery extend the runtime to 80 hours in standard GPS mode and up to 65 days in smartwatch mode. There’s enough extra power for the longest ultraruns without constantly having to think about recharging. Innovative training and analysis features, along with heart rate measurement using a Pulse Ox sensor, help you get the best out of yourself while keeping an eye on your reserves. Features like the trail running-specific V02max calculation, the optimized ClimbPro function with detailed downhill information, and the ultrarun app with a rest timer enable perfect competition preparation and execution. Thanks to multi-satellite reception, track navigation, and ABC sensors, you can maintain your orientation even in challenging terrain. The UltraFit nylon strap ensures a perfect fit and additionally reduces the weight of the watch.
