• Upgraded AMOLED Screen: The smartwatch has a 1.95-inch HD AMOLED touchscreen that shows bright and colorful pictures, even in sunlight. You can always see the time because the screen stays on all the time, and it saves energy—up to 40% less power than other screens!

•Waterproof and Tough: This smartwatch is IP68 waterproof, so you can wear it in the rain, wash your hands, and even swim! It has passed 15 tough tests to make sure it can handle all kinds of weather, from deserts to rainforests. (Just avoid keeping it underwater for too long to make it last longer.)

• Bluetooth Calls and Messages: Stay connected without your phone! You can make clear calls and listen to music right from the watch. It also gets your text messages and notifications from apps like Facebook and WhatsApp, so you won't miss anything important.

•100+ Sports Modes and Long Battery Life: With over 100 sports modes, you can track activities like walking, running, and cycling. The battery charges in 2 hours and can last 5-7 days of use, or up to 5-10 days on standby. Stay motivated during your workouts!

• Heart and Sleep Tracking: The smartwatch keeps track of your heart rate, blood oxygen, and blood pressure in real-time. It also monitors your sleep patterns, showing how well you sleep. You can use the app to check your health reports (but remember, it’s not a substitute for seeing a doctor!).

• Voice Control and Compass: You can talk to the smartwatch to make calls, check the weather, and play music. It now has a compass for navigating outdoors, plus useful features like alarms, calculators, and reminders to drink water.

• Interchangeable Straps and Custom Dials: The smartwatch comes with two straps—stainless steel and silicone—so you can change your style easily. With the app, you can choose from over 200 cool watch faces or use your own photos to personalize your watch.

• Charging Tips: Use a low-power charger (no more than 5V-1A) to charge your smartwatch. If you use a charger that's too powerful, it can cause problems. The safest way to charge is with your computer's USB port.
