Perfect for keeping it under water, hanging tied to the diving block, while swimming
The Casio HS-80TW, the full black version, and the Casio HS-70W (which is black, grey and yellow and is being reviewed here) share the same watch box but in different colors. It is a box that makes them super tough and very long lasting. They are the best value for the money. The only difference between, other than the color of the box, is that the HS-80TW has additionally a countdown timer and a super complete football mode. If you are not a football referee you are probably doing fine with the HS-70W. I have had two HS-80TW in almost eight years of use. I have used them alternatively several times a week for swimming. During my training they are always under 10 centimeters of water, hanging tied to the diving block and I press the bottoms under water a lot of times. After eight years, one of them gave up and I had to buy a replacement. I decided to go for the HS-70W, instead of the HS-80TW, because of the different esthetics, which help me to differentiate them. Since the boxes are exactly the same, I am expecting the HS-70W to last as long as my two HS-80TW.

使いやすい
安物買いの銭失いで,何度も色んなストップウォッチを使用してきましたが、このストップウォッチの機能と押しやすさは抜群に良き。もっと安いものもあるけど、そこは我慢してこれにすべき。壊れてないけど壊れてもこれをリピートすると思える。

本体以外の耐久性に難あり
デザインはG–SHOCKを意識したものだが、表示やボタン配置など基本に忠実で使いやすい。コストパフォーマンスは高いが、本体とストラップを繋ぐゴムリングが経年劣化で切れる。首への負担を和らげる目的での採用だとは思うが、本体は頑丈なのにこの部分だけが残念でならない。

手軽さと安心感
資格試験の実技練習でタイマーが必要だったため購入しました。お手軽で使いやすくて、いい商売道具になりました。軽くて、女性の手のひらにちょうどいいです。色のバリエーションがあるとさらにいいですね。

Coaches, this is the stopwatch you've been looking for!
Finally found the stopwatch of my dreams after trying others that were terrible quality. This one is the winner by far. I use this for track and field. If you know, you know, that a dependable stopwatch is imperative when timing athletes' races and relay splits. This watch has proven to be functional and consistent. Thank you Casio!
