Multiple Sports Modes for Active Users

• Workout duration
• Steps & distance
• Calorie burn
• Heart rate during exercise

Reviewing these stats in the H Band app helps you understand progress, adjust intensity and stay motivated.

Week-Long Battery Life & Fast Magnetic Charging

Inside the sleek body is a 180mAh lithium polymer battery that’s optimized for real-world use:

• Up to 7–10 days of standby time
• Around 3–5 days of typical daily use

You can comfortably wear the watch through workdays, workouts and weekends without daily charging. When it’s time to top up, simply snap on the magnetic pin charger for a clean and hassle-free experience.

Bluetooth 5.4 – Stable, Low-Power Connectivity

Thanks to Bluetooth 5.4, the YES Curve Flex maintains a strong, energy-efficient connection with your smartphone. Once paired with the H Band app, you can:

• Receive call notifications, SMS and app alerts on your wrist
• See message previews without taking out your phone
• Use the built-in speaker and microphone for hands-free calling when connected

This makes it ideal for busy professionals and on-the-go users who need to stay connected while keeping their phone in pocket or bag.

Premium Aluminum Alloy Design – Light, Strong & Stylish

The Curve Flex is crafted with a full aluminum alloy middle frame and back case, combining durability with a refined, lightweight feel.

Available in Dark Gray and Rose Gold, it looks just as good with business wear as it does with sports outfits. The soft silicone straps offer all-day comfort and can be easily swapped to match your style.

The IP67 waterproof rating means the watch is protected from sweat, splashes and rain – perfect for everyday wear and intense workouts.

Global Multi-Language Support

The YES Curve Flex is ready for a global audience. Both the watch interface and the H Band app support multiple languages including English, Chinese, German, French, Spanish, Japanese and many more.
