When evaluating hardware, focus on the Processor (CPU); high-end models should feature Snapdragon Wear 4100+ or newer chipsets to ensure smooth UI performance. The RAM/ROM configuration is critical, with 2GB RAM and 16GB/32GB storage being the standard for supporting third-party apps. Additionally, verify the Display Type, prioritizing AMOLED screens for better sunlight visibility and power efficiency, and ensure the Battery Capacity is at least 400mAh to 600mAh to guarantee a minimum of 24-48 hours of active use.
