This is the Smartwatch QS16 PRO. The body is black, and the band is beige. I've used it for about two days! I'll also include a black replacement band. I bought it for about 2600 yen! No box. [Included Items] Main unit Replacement band Charger Instruction manual [Exercise Management] In sports mode, it records data on steps, calorie consumption, distance, and heart rate, allowing you to reasonably manage your exercise volume and time. [Health Management] You can measure your heart rate just by wearing it on your wrist, and after syncing with the app, you can see your health data at a glance. *Note: Measurement results are for reference only and are not recommended for use as medical diagnostic data. [Incoming Call Notifications/App Notifications] After connecting this smartwatch to your smartphone, you can receive not only incoming call notifications and email notifications, but also emails from apps such as LINE, Twitter, Instagram, Facebook, and Whatsapp, and they will be displayed on the smartwatch screen. You won't miss emails whether you're in a meeting or at the gym. You can reject calls on the smartwatch by clicking the screen. [Ultra-Long Battery Life & Compatible Models] With a 260mAh large-capacity battery, it can be used for up to 8 days after charging for about 3 hours! Compatible with smartphones running Android 4.4/iOS 8.0 or later, and Bluetooth 4.0 or later. [Various Style Watch Faces] Various main interface screens are available, allowing you to set your favorite main interface. [High-Precision Dedicated Chip] It simultaneously measures heart rate through a dedicated sensor built into the smartwatch, an essential function for health management. [3ATM Waterproof] It also has a 3ATM waterproof function, so you can use it without worrying about getting wet on rainy days, satisfying your daily waterproof needs. This smartwatch complies with the 3ATM waterproof level, so it can withstand 10 minutes of static water pressure at 30 meters, but it does not guarantee waterproofness in water at a depth of 30 meters. (※Note: It is not completely waterproof, so please avoid using it for diving or in places with steam, such as hot springs.)
