This is an itDeal W8 smartwatch. I used it once and then stored it. I have confirmed that it works. The box is dirty, but the spare band is unused. You use it by downloading the HBand app and connecting via Bluetooth. It has features like running, pedometer, vital signs monitoring, sleep tracking, stopwatch, and notification functions. You can also choose from several watch faces! The color is navy. I'm sorry, but there is no instruction manual. Everything in the photos is included. To charge it, simply remove the bottom band and plug it into a USB adapter. Please note that I am also selling this elsewhere, so I will prioritize the first person to purchase, and may cancel the sale in some cases.
