Q: Mine keeps going from 12 hours to 24 hours. How do I keep it at only the 12 hour setting?

Hello from Marathon Watch, You can easily change the Marathon CL030064BK from 24 HR to 12 HR by pressing the MODE button on the back of the clock. Press and keep you finger on the button until you see the the hour flashing, press it 6 more times and you will then see 24hr flashing. To change the 24hr to 12 hour press the up or down arrow.
