I expect there are a number of Backroomers out there who also have this watch.

Please would one of you explain to me how I can alter the setting from 24 hours to 12 hours each of a m and p m.

Hey Stu

Bottom right button. Easy fix. You can bump it by accident quite easily and keep knocking it back and forth.

Excellent cheap watches though!

The "24 HR" on the display is a bit of a giveaway.

Hello,

If you still didn't find the solution so I suggest the best way is to google it because I am not completely transferring this technique to you by writing on this forum.

A very obvious segway to you posting some spam, eh 'John'? The issue was already resolved ages ago.
