    This stopwatch is the best on the market in and out of the pool.  Not only is it great for splits, it is amazing for cloning shinies.  My shiny clone success rate has never been higher in Pokemon X for the Nintendo 3DS.  If you want fast swimmers and a ton of shiny mews, this is the watch for you!

    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.

    The main reason I purchase was it helps me in keeping splits, laps, times. The watch keeps time very well.

    I am a coach and love how easy this watch is to use and operate. Great for getting splits and stroke rates.

    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.

    love that this watch gives us the splits we need without figuring them to give our swimmers more feedback on their races. easy to use.

    I reallly like this watch, it does all the splits and everything for you when timing swimmers or anyone. No math required! Its also waterproof so if it drops in no big deal.

    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.

Founded in Southern California in 1985, TYR™ has since developed a reputation for high-quality products and equipment. TYR competition swimwear and triathlon gear have been a dominant force in their respective industries. The company is also known for its TYR goggles, swim apparel, triathlon wetsuits and a wide variety of swimming equipment.

TYR was the first company to introduce a pair of goggles designed to fit a woman's face (the TYR T-72). TYR was also responsible for the famous red bathing suits featured on the hit television series "Baywatch." TYR consults with current and former athletes when developing its products. Swimmers know that TYR is a leader in swimsuits, warm-up suits, and swim training equipment. The TYR Tracer Series is one of the most advanced technical suit lines on the market. The TYR Hurricane wetsuits and the TYR Torque collections include top-of-the-line suits for the competitive swimmer.

TYR has also moved into competitive running equipment. From running shirts to shorts, its apparel is designed with the runner in mind. Built with moisture wicking fabric and antimicrobial material, TYR running apparel is designed to give the athlete the most comfortable, dry clothing on the market.

The name "TYR" is derived from the Norse god of warriors, who is said to have embodied victory and glory. Much the same can be said about the athletes who started TYR. Executive Vice President, Steve Furniss, was an Olympian who competed in the 1972 and 1976 Summer Games, and captained the 76th U.S. Olympic Swim Team.
