  • 12/17/2018 Great watch! Wish it didn't beep...

    4 Review Stars By sgibson

    Has an annoying beep with every button push. I can see where some would like that to know that it pushed, but I find it a little annoying. I'm sure I'll get used to it. Otherwise, great product from the sense of build quality, functionality and comfort to hold. Great watch especially for the price! I just might have to figure out if I can disconnect the speaker.

    5 Review Stars By Ken

    After reading other reviews I decided on this watch. Big numbers, easy to use, fits well in my hand. I would recommend this to anyone entering the swim game to track your childs progress. Thanks.

  • 7/6/2018 Display is better and easier to read, even outdoors.

    5 Review Stars By Swim Mom

    I am a parent, referee, and board member for a summer swim team. We have many different stop watches, but when we needed more, this was our first choice.  Others have the same functions, but what makes the TYR stand out is its display.  Side by side, the TYR is easier to read than other brands in similar function, size and display.  We are outdoor all season and it is even easy to read in the bright summer daylight.

  • 1/4/2014 Awesome stopwatch!

    5 Review Stars By Kim

    This is a great stopwatch, especially for taking splits.  My daughter swims the 500 free and I use this stopwatch so she can see her splits after each race. It's easy to use and read.


  • 3/8/2017 Love the 3-line display

    5 Review Stars By Mfkelley

    I bought this stopwatch to time my daughter in distance events. It has enough memory to recall all the 50 splits. I really like how the 3-line display shows the most recent split, the cumulative time up to the last split and the running time for the event. This helps me give her feedback during the swim when I'm doing lap counting. The stroke rate feature is interesting but I think it would be better if it let you count strokes over a whole 25yards or 50 meters rather than just calculating based on 3 strokes.

  • 8/24/2012 Excellent stopwatch

    4 Review Stars By mart1158

    I have been coaching swimming for about 10 years and have used many stopwatches. That being said, this is the third one of this particular model that I've purchased. I love it.

    For lack of a more intellectual term, the buttons push well, and don't double click, the display face is very easy to read, and it has all the functions that I could ever need in a stopwatch.

    The only things that I might count as cons (and thus the 4-star rating) are that the beep when you push a button is sort of irritating to me, and water droplets tend to accumulate under the face.

    That being said, I have never had an issue with this model of stopwatch, and I don't anticipate there ever being one. Highly recommend.
