Apple has released watchOS 26.3, a software update for Apple Watch devices that comes two months after the previous watchOS 26.2 version. The update is available for free to users with an iPhone running iOS 26.3 and requires at least 50 percent battery charge while the watch is placed on a charger for installation.

According to Apple's release notes, watchOS 26.3 includes unspecified bug fixes and security updates. The company did not discover any new outward-facing features during the beta testing process, suggesting this is primarily a maintenance release rather than a feature update. This follows the September launch of watchOS 26, Apple's major operating system update for Apple Watch.

Users can download the update through the Apple Watch app on their iPhone by navigating to General > Software Update, or directly through the Settings app on the watch itself. The relatively short time between watchOS 26.2 and 26.3 indicates Apple is maintaining a rapid update cadence for its wearable platform, focusing on stability and security improvements between major feature releases.
