Connectivity is robust with Bluetooth 5.3 (some sources cite 5.2), Wi-Fi, and NFC for mobile payments via Google Wallet. The watch runs on Wear OS by Google + RTOS, providing access to a rich ecosystem of Google apps (Google Assistant, Google Play, Google Maps, Google Calendar, etc.) and a smooth, responsive user interface. Its durability is further cemented by IP68 dust and water resistance, 5ATM water pressure rating (suitable for swimming but not diving or hot water activities), and MIL-STD-810H military-grade certification, ensuring it can withstand extreme temperatures and environmental stressors.
