First of all, how to turn off the alarm clock. In normal mode, press and hold the D (Reset) key. While holding down the C (Start) button, you should hear a beep. There should no longer be a black triangle at the top of the clock in a circle with the days of the week on AL. By the way, a chronograph is a chronometer. Now for the overview, although the instructions are vague and a bit difficult to understand, you can get the hang of it. It's beautiful and delicate (for a sturdy watch) just like the pictures and the face is small. I wish you could see digital time a little better but it still works and would be great for nurturing.
