How do you set time on an bijoux terner watch?

Press "mode" until it shows the date, day, and time. Hold down the "light" button until it beeps. Now, if you press the "mode" button, you will scroll through each of the things you might want to set. When whatever you want to set is flashing, press the "start" button and that will make it go up by one. When you are done setting the first thing you want to set, press "mode" again and it will go to the next thing. When you're done, hold down the "light" button again and it will be set.
