Firmware: View and Update | iOS
To view the current firmware version and check for a pending update,
On the NOW tab, tap the Settings icon in the upper rightmost corner,
Scroll down to General, then tap Device Details,
Tap the Firmware update option, if a newer version is available.
The latest version should be 2024.07.30.1.
During installation, your NOWATCH and app may disconnect multiple times; this is expected.
