This black and yellow smart watch features an impressive range of outdoor environmental sensors, including an altimeter-barometer, compass, and thermometer. New features include blood oxygen measurement, cardio load status, sleep measurement and analysis, sunrise and sunset time display, and moon age data.

Our bio-based resin watch band is made from renewable organic materials that reduce environmental impact and facilitate the shift to a circular economy.

The Smart Alarm function measures your sleep state and selects the optimal time for a sound or vibration alarm. Its rechargeable lithium-ion battery can be powered by USB cable or solar power, which means you'll never have to worry about running out of juice. So, whether you need a GPS watch for running, an all-inclusive watch for cycling, or a watch to track swimming laps, the GBD-H2000-1A9 is fully equipped for any and every sport you love.
