If you hate to wear watches, you can try this way to know what time is. , and the answer is Digitalclock T-shirt!. Coming only in black the Digital Clock T-Shirt has an electro-luminescent panel on the front that displays the current time in glowing green numbers. And if the static display doesn’t fit your style you can select up to 8 different flashing patterns or even switch it to a stopwatch mode.
The shirt is powered by 4 AA AAA batteries which reside in a small, discreet pocket inside the shirt and will last between 12-36 hours depending on the flashing mode selected.
But I think it will little bit a problem to see the time, may be you need ask someone to see your t-shirt first.
