As expected
Color: Gray/Gray/Digital
Just an old school digital timex. Tried and true. Has both 12hr and 24hr function on the time setting. Has a standard stop watch and timer. The battery is great, just as it always is on a timex. Good water resistance and very easy to use. Overall very good watch for the price!

Can’t read numbers
Color: Gray/Gray/Digital
Numbers are too small to tread on a 44mm watch

Cute but very inexpensive
Keep in mind you get what you pay for. That said, this is a very cute watch and my granddaughter loves it. It was a Christmas gift and when she first opened it and set it, it would not run. Later, when I was working on requesting an exchange, I noticed it was running. Hopefully it will continue to run and she will be happy with this watch. It's a unique style and perfect for a teenage girl.
