The Y68 smart watch is a popular, entry-level fitness tracker. The letters "UKGF" in the product name likely refer to a specific seller or marketplace designation and not an official brand name. The watch is known for its minimalist design, direct USB charging, and basic smart functions. 
Key Features and Specifications
Design & Comfort: Features a lightweight design with a skin-friendly soft TPU (Thermoplastic Polyurethane) wristband, making it comfortable for all-day wear. It often has a rectangular case shape and single touch key for operation.
Charging: Utilizes a unique, quick-release detachable wristband design that reveals a built-in USB-A plug, allowing it to be charged by plugging directly into any USB interface (like a power bank or laptop) without needing a separate charging cable or stand.
Connectivity: Uses Bluetooth 4.0 or above to connect with smartphones running Android 5.0 or above, or iOS 9.0 and above, through a companion app (commonly FitPro or Da Fit).
Functions: Acts as a "smart life assistant" by monitoring various health and activity metrics.
Activity Tracking: Tracks steps, distance, calories burned, and multiple sport modes.
Health Monitoring: Includes sensors for heart rate, blood pressure, and blood oxygen (SpO2) monitoring. Note: Data from these consumer-level sensors should not be used as medical reference.
Smart Notifications: Provides vibration alerts for incoming calls, messages, and social media notifications (SMS, WhatsApp, Facebook, etc.).
Other Features: Includes sleep monitoring, sedentary reminders, alarm clock, and remote camera control.

Product Limitations
Water Resistance: Most listings specify it is only "life waterproof" or "surface splash waterproof" (e.g., IP67 rated on some listings, but effectively splash-proof only), meaning it can handle hand washing and sweat but should not be worn for swimming, showering, or soaking in water.
Accuracy: Health tracking data provides general wellness insights but lacks the clinical precision of medical-grade devices.
Operation: Typically operates via a single touch key interface, not a full touchscreen.
Battery Life: Generally offers a usage time of 2 to 5 days on a single charge, with a standby time of around 7-10 days. 
Overall, the Y68 is a highly affordable entry into the smartwatch market, offering essential fitness and notification features for everyday lifestyle tracking.
