Overview
Built within a 45 x 45 x 12.3 mm aluminum housing weighing 36.7 grams, the circular chassis integrates a 1.4-inch LTPO AMOLED display capable of 3000 nits peak luminance behind Corning Gorilla Glass 5. Operating at a resolution of 456 x 456 pixels (~320 ppi density), the panel provides clear legibility in direct sunlight while dynamically managing power consumption through variable refresh rate behavior. Internal processing is driven by Qualcomm’s Snapdragon W5 Gen 2 silicon—fabricated on a 4 nm process node featuring four Cortex-A53 cores clocked at 1.7 GHz and an Adreno A702 GPU—paired with 3 GB of RAM and 64 GB of eMMC storage to maintain fluid navigation across Android Wear OS 7.
Physical sealing achieves an IP68 dust-tight rating and 5 ATM water resistance certified for immersion up to 50 meters, accommodating active aquatic use alongside an integrated biometric array that includes certified ECG, SpO2, continuous skin temperature, and skin conductance sensors. The wireless subsystem incorporates dual-band Wi-Fi 6, Bluetooth 6.0, dual-frequency GNSS tracking across GPS (L1+L5) and Galileo (E1+E5a), NFC, and Ultra Wideband (UWB) support. Power is sustained by an internal 465 mAh lithium-ion cell paired with a stepped wired charging profile that delivers 50% capacity in 15 minutes, 80% in 30 minutes, and a full cycle in 60 minutes, passively managing thermal dissipation across the metal enclosure without inducing charging throttle states.
