The Fitbit Blaze - an intelligent fitness watch - helps you get the most out of every workout and every day. This revolutionary device features cutting-edge technology with a versatile design, tracks your workouts, monitors your performance statistics, and measures your progress. Features like continuous heart rate monitoring with PurePulse and the multi-sport mode enhance every workout. Next-generation functions such as GPS connectivity (phone must be nearby) and FitStar workouts on your wrist help you take your fitness to the next level. The internal memory records detailed, minute-by-minute tracking of movement data (for up to 7 days) and the daily totals for the last 30 days. Heart rate data is recorded during workouts in 1-second intervals and in 5-second intervals at all other times. The Blaze is not suitable for swimming, and it is recommended to remove the tracker before showering, as it is best for the skin to keep the band dry and clean. With interchangeable bands and frames, as well as a customizable watch face on the high-resolution color touchscreen, you can adapt your style to any occasion. All this and more is offered by the Fitbit Blaze. With this elegant timepiece, achieving your goals becomes a breeze. Size S fits wrists with a circumference of 14 - 17 cm. Size L fits wrists with a circumference of 17 - 20.5 cm. If the Fitbit Blaze gets wet or if you sweat while wearing it, remove it and ensure the band is completely dry before putting it back on. Occasionally take off the band to give your wrist a break. Clean the band and your wrist regularly.
