Thank you for viewing! This is a brand new, unused item! I purchased it last year and have kept it at home for a while. Thank you for your purchase if you understand. WAPIK Smartwatch S10 Color: Black 【Bluetooth Calling Function】 The smartwatch has a high-performance calling function, and you can have clear conversations with the built-in microphone and speaker. By linking with your smartphone, you can not only reject calls but also make calls. If your hands are busy with housework or exercise, you can make fluent calls without taking out your smartphone. The name or phone number of the other party will be displayed on the smart watch screen. Furthermore, you can synchronize your contacts and display your call history. You will be convinced of its convenience once you use it. (Note: When using Bluetooth calling and music playback functions, you need to connect "S10" audio Bluetooth pairing.) 【AI Voice Assistant, Music Player & 3D Dynamic Watch Face】 With the latest voice assistant function, you can simply talk to the voice assistant to play music, set alarms, call up your smartphone's Siri, access news, check the weather, make calls, and more. 【IP67 Waterproof & Multiple Sports Modes & Long-Lasting Battery】 It has IP67-level waterproof and dustproof performance, and is compatible with sweat, rain, and splashes. You don't need to remove it when washing your hands or face in daily life. * Bathing, saunas, hot spring water, steam from hot springs, and high water pressure will cause malfunctions. Equipped with a 290mAh large-capacity battery, it lasts for about 7 days with a full charge of about 2 hours. This saves you the trouble of frequent charging. Charging starts when you connect the included magnetic charging cable to the charging terminal of the sports watch. (The sustainable usage time varies depending on individual usage.) 【Compatibility】 Compatible with smartphones with IOS9.0 / Android5.0 or higher.
