zolohoni Square Men's Digital Watch Big Numbers Dial Large Face Waterproof LED Watches with Alarm Date Stopwatch

Q: This watch has no display. How does it turn on? No instructions cover this. Is it dead?

Its easy to turn on, it comes with instructions. But it broke in two days, and it doesn't really light up as bright as the picture, or stay lit, which was the reason I got it for my boyfriend. We tossed it and got another watch.

Q: is display on all the time or do you have to push a button to see time

It displays all the time. Here is video for light turn on & off. Hope it can help. (Just press the light button which is located on the upper left hand corner.)
