Easy to use Simple & easy to use.
Color: Black/Black/ Wjite Digital
Would have given 5 stars except the date font was too small. Great price for a basic watch that gets the job done

THIS WATCH IS NOT WATERPROOF AT 8 FT
Color: Black/Black/ Black Digital
DO NOT BUY TIMEX WATCHES - TIMEX ARE LIARS- I just called Timex and was told "a 30 meter rating is only for washing hands, not for swimming" This is a BIG FAT LIE. If the watch is only for swimming then SAY THAT!
I AM VERY DISATISFIED- THIS WATCH LEAKED IN 8 FT OF WATER WHILE SWIMMING IN MY POOL .
-ALSO, WATCH FACE IS VERY DARK AND HARD TO READ. Even if it didn't leak I would be very unhappy.
I want a refund? This watch is only a week old when it failed.
DO NOT BUY TIMEX WATCHES

Great!

Great, Just as I remembered them! The only difference is, a shorter band. I thought I had small wrists for a man, but with this band I have to use the last hole to be comfortable . I may add one more hole to the band!
