S99: Advanced dual-frequency GPS navigation
You lace up your running shoes and head out the door. Your phone stays on the kitchen counter. The S99 GPS sports smartwatch handles everything else: accurate route tracking, heart rate monitoring, and even that call from your spouse without breaking stride.
Under the 1.43-inch AMOLED screen, dual-frequency GPS locks onto satellites quickly, even in dense urban canyons or forest trails. The 500mAh battery lasts up to 10 days, so you charge it less—and wear it more. At night, it tracks your sleep stages, giving you a readiness score for the next day. Need a moment to relax? The breathing training guide syncs with your heart rate to calm you down.
With 100+ sports modes and Bluetooth calling, the S99 adapts to your active life. Check the weather before your hike, control your music during a workout, and read notifications without pulling out your phone. It’s a daily companion that fades into the background until you need it.
