Advanced Health and Fitness Features
Despite its smaller size, the 43mm model retains flagship capabilities including the 60-second Health Check-In feature, enhanced dual-frequency GPS, and OnePlus’s unique dual-engine architecture. The Snapdragon W5 Gen 1 chipset ensures smooth Wear OS performance while maintaining impressive battery efficiency.
The watch promises up to 5-day battery life from its 354mAh cell, matching the larger model’s endurance despite the size reduction. This achievement highlights OnePlus’s optimization improvements in their latest wearable technology.
