Sony SmartBand 2 SWR12 - Black

The heart rate monitor constantly takes your pulse, so you can see what makes your heart race or how hard you’ve pushed during a workout. See what makes you calm, excited and everything in between. Using heart rate variability (HRV), the milliseconds between each heartbeat, SmartBand 2 measures your pulse and stress level during everyday activities. By tracking your recent activity data including exercise, stress and sleep quality, SmartBand 2 gives you insights to know yourself better.Feature- 3 LED indicators- Notifications- Bluetooth® 4.0- NFC- Waterproof* IP68- Standard micro USB for charging- Keep going for up to 5 days in STAMINA mode- SmartBand 2 host app (Android™ or iOS)SpecificationProduct Model:Sony SmartBand 2 SWR12 - BlackSystemOS:AndroidWirelessBluetooth:V4.0FeaturesColour:WhiteSizeDimensions (L x H x W):40.7 mm x 15.3 mm x 9.5 mmWeight (with battery):25 g
