Ultra-Thin Premium Metal Design：2.8mm ultra-slim zinc alloy case (3x thinner than standard 9.8mm smart bands) with a refined square dial, delivering a striking, lightweight profile (~41.2g) that blends elegant style with all-day comfort—far slimmer and more eye-catching than bulky alternatives
All-Day Ergonomic Comfort Fit：Ergonomically curved body paired with your choice of breathable perforated silicone or smooth stainless steel mesh straps, wrapping snugly around your wrist for zero fatigue even during extended wear, whether at work, the gym, or overnight sleep tracking
24/7 Comprehensive Health Monitoring：Equipped with a precision optical sensor to track real-time heart rate and blood oxygen; scientific sleep analysis (deep/light/REM sleep + awake status); and dedicated female physiological cycle reminders (menstrual/fertile/safe periods) to empower proactive wellness management. Note: This is not a medical device; health data is for reference only
Accurate Fitness Tracking & Smart App Sync：Precisely counts steps, calories burned, distance, and active hours; supports multiple sport modes (outdoor/indoor running, cycling, etc.); syncs seamlessly to the Nx Wear app via Bluetooth 5.3 for real-time insights, goal tracking, and habit-building—compatible with Android 6.0+ and iOS 10.0+
Long-Lasting Battery & IPX8 Waterproof：Large-capacity battery with energy-saving algorithms delivers 7 days of daily use or up to 30 days of standby on a single charge. IPX8 waterproof rating (100m) lets you swim, dive, or shower worry-free—no need to remove the band for water-related activities
