Question: how long does it take to install your apple watch?
Answer: In many situations, you can finish the watchOS 5 upgrade in about 30 to 60 minutes and a watchOS 5.3. 1 update in less than 15 minutes. The watchOS upgrade process is slow compared to iOS updates, so plan for that. It took us 16 minutes to install and then about 3 minutes for the watch to reboot before we could use it.
