Apple today released a new software update for the Apple Watch, upgrading watchOS 3.1 to watchOS 3.1.1. The watchOS 3.1.1 update comes more than two months after thewatchOS 3 was provided to the public in September and marks the second update to the operating system. watchOS 3.1.1 has been in testing since October 31.
watchOS 3.1.1 can be downloaded through the dedicated Apple Watch app on the iPhone by going to General -> Software Update. To install the update, the Apple Watch must have 50 percent battery, it must be placed on the charger, and it must be in range of the iPhone. An iPhone running iOS 10 or later is required to download the new software, but it is available for all Apple Watch models.

No major outward-facing changes were discovered in watchOS 3.1.1 during the beta testing period, suggesting it focuses on bug fixes and performance improvements. watchOS 3.1.1 does support the new Unicode 9 emoji that have been introduced in iOS 10.2 and it includes a new feature for changing the skin tone of emoji.
watchOS 3 completely overhauls the interface on the Apple Watch, introducing a dedicated app dock, instant launch apps, new watch faces, and new complication options. There are new Activity sharing features, a “Breathe” app guides users through deep breathing sessions, and an SOS feature can automatically call emergency service.
