The issue has been reported by Hermoso on our iOS 16 Public Beta review page:

“My iphone is showing 24 hour time on Lock Screen although I’ve switched it to 12 hours.”

We couldn’t replicate the issue on our test devices. Nevertheless, I’ve found similar report on Reddit:

How To Fix 24 Hour Time Bug

This is an early iOS 16 clock bug that should be fixed until the public release. In the meantime you can apply the following:

1. Reboot iPhone

The first step is to restart your device. A fresh boot could flush minor glitches that could prevent the current time from displaying in the chosen format on the Lock Screen.

Use the the force restart trick to quickly reboot your device.

Tip: I recommend you to open Settings -> General -> Date & Time. Enable 24-Hour Time, disable it and restart device. Does it work?

2. Add New Lock Screen

If the problem persists, create a new Lock Screen:
