We will show you how to download watchOS 6.2 on Apple Watch ahead of its official release which is set for next week.

Apple seeded the GM version of iOS 13.4 / iPadOS 13.4 and watchOS 6.2 to developers this week. Apple also promised that it would release the final version of iOS 13.4 on March 24, which falls in the coming week - Tuesday, to be more exact. Therefore, it is safe to assume that the company will release watchOS 6.2 on the very same day, too.
