This is so frustrating! I ordered the black model 19 available above. Firstly the instructions they gave me are for a different watch even though the tag they gave me matches the actual model I bought. Second, the site is rubbish when it comes to giving hints. After playing around with it for a while, I was able to understand something.

Timer: 1 ) Press B twice to go to the timer (TMR should be displayed above) 2) To start the timer press C and to pause it press again 3) To restart the timer from the beginning start, pause it first and then press D. 4) To reset the timer to another time, pause it first and then press and hold D for about 3 seconds. A beep will sound and the hour marker will start flashing. Press C to set the hour, then press D to move to the minutes and make them flash, then press C again to set the minutes. Press D again to end the timer (seconds setting is not available). 5) To exit the timer and return to the time display (you can do this and it will continue to run in the background if you haven't stopped it), press B and a higher pitched beep will sound indicating you have returned to the time display.

The bell icon should appear in a circle. Each alarm clock has its own icon, so if all 3 are on, 3 bell icons should appear in the circle. To turn off the alarm, press C again. 5) To set an alarm, scroll to it and hold D for about 3 seconds. A beep will sound and the hour marker will start flashing. Press C to set the hour, then press D to move to the minutes and make them flash, then press C again to set the minutes. Press D again to stop the alarm.

I couldn't figure out how to change the color of the light as the description says it's a feature built into the watch. I've tried long pressing A and pressing a few times to no avail. All in all, this is a very night watch for the price. The symbols are easy to read and there are many features that many other watches only partially have. First I wanted to give it a rubbish review as I couldn't figure out the buttons and it would be useless if I didn't know how to set it up. Now that I know how it works, it's very functional. However, I encourage the seller or manufacturer to include instructions. Not everyone will spend as much time as me trying to figure this out. I'm giving it 4 stars because of the lack of instructions.
