Setup, Compatibility & Care
To begin, pair your Apple Watch Ultra 3 with your iPhone using the Watch app, ensuring you are running the latest software version. The watch is compatible with standard Apple Watch bands, but the 49mm size works best with bands designed for the Ultra series to ensure a secure fit. For maintenance, rinse the watch with fresh water after exposure to saltwater or sweat to prevent residue buildup. Use a soft, lint-free cloth to keep the sapphire crystal display clean, and avoid abrasive cleaners that could damage the titanium finish.
