Great value, great quality.
Color: Black/Black/ Black Digital
My husband bought this watch for work. He can’t have his phone on him at work so this watch has been very useful for him. He sweats a lot and works in a warehouse. He has a nicer “church” watch I bought him as a wedding gift and he actually has started to prefer this one.
There are only two little annoyances (which might be able to be fixed) every hour the clock beeps and that the alarm goes off every morning including weekends. Those things might be features which some desire and some that even we are impressed by so 🤷🏻♀️ as I said, those minor issues might be fixed if we look into them but my husband doesn’t find them as bothersome as I do and he’s the one who wears it.

Would definitely recommend this watch.
Color: Black/Black/ Wjite Digital
Nice manly watch. Many Timex watches are too small. I love the size of this one and yet it's still lightweight. The face of the watch is neatly organized and very clear to read. Indiglo light works well at night. Only thing I see missing from this watch is a countdown timer. It has a stopwatch.

Big face, easy to read Timex quality at superior price
Color: Black/Black/ Wjite Digital
Great watch at amazing price. Better looking and much cheaper than current timex ironman models. Large face and numbers = easy to read. Has alarm and stopwatch functionality. Intuitive interface.

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
