We wanted to make charging your Apple Watch utterly effortless. And now, it charges up to 33 percent faster when paired with Apple Watch Series 7, so you can reach 80 percent charge in about 45 minutes. Simply hold the connector near the back of the watch, where magnets cause it to snap into place automatically. It’s a completely sealed system free of exposed contacts. And it’s very forgiving, requiring no precise alignment. Fast charging is only compatible with Apple Watch Series 7. Other models will have regular charge times.
