    I wanted something simple and easy to use and that is what I got. I didn't want to count laps and forget where I was. You still have to press the button each time but at least you know which lap you are on. I also just time myself on one lap and then do the math later. So either way, you can make it work. So far, it is working great!

    Has a timer, stopwatch, big numbers, date and day; all the things that are important to me in an "every day watch."  Plus it has a sleek look and was a great value!

    I had a Timex Ironman watch that has lasted over 15 years, requiring only periodic strap replacements.  Because it was showing the wear, I bought this new version.  Love the interval timer, and it's a very attractive watch.  However, this watch started taking on water and fogging the screen after only ~1.5 years.  I am only a lap swimmer, no deep water diving or scuba.  And the first time it started fogging, I believe it was actually after a shower!  Around the same time, the strap also started to split (and they are not replaceable.)  I will be looking to a different brand.

    This Timex model is a good choice for runners not interested in using GPS or noncompetitive swimmers.  The reason I gave it only 3 stars is because 2 out of 3 Ironman Sleeks I have owned needed repairs within the first year.  The crystal of my first watch started leaking in the pool, ultimately causing it to stop working within the first year.  With my current watch, the indiglo light function stopped working about 9 months after purchasing it.  Timex has been accommodating each time about replacing the watch.

    I used this watch for about two years. It was a good watch. The watch still works but with the band design - it can't be replaced.
    You're only going to get about two years out of this flimsy band if you run and swim in it 5+ times a week

    I bought this for my husband as a gift. He is training for a tri and is now swimming enough laps in a row that he forgets where he is in his count. He said it has worked great and while he was concerned that it was small at first he really likes that aspect of it. It is not bulky, so it does not get in his way or restrict his wrist movement at all. He is only wearing it for laps and not as an everyday watch. The band just fits - if the intended wearer has a very large wrist you may want to get an extra large band.

    My Granddaughter loved it!  She likes that it will be able to count her laps, and swim in it.

    This product has the interval timer which a previous purchase did not. However with this watch and the other Timex I purchased at, the price is spot on. The first I don't mind at all wearing every day. Is very stylish. Can't want to get this one as an active part of my running!

    Bought to replace a similar one that I wear 95% of the time.  Not too bulky.

    I'm training for a triathlon and use this watch all the time including in the water and it works great! I had a watch like this before and it lasted for about 5 years. Hope this one lasts as long! I got the blue and the light blue accents on the band got a little bit yellow after being in chlorine for the first time, but that has seemed to worn off- maybe it was just that pool.
