So far I am happy with this watch. Note that this particular model is gray/pink, rather than black/pink. The numbers are large and easy to read, though as a consequence the watch face is rather large. I use the chronometer frequently when running. The lap/split button is large and easy to access. It is easy to review the split times afterwards. When setting the watch, you can go forward or backward, which saves time for small backward adjustments. If you don't use all of the features (all three alarms, etc.), you change the settings so that they don't appear when you cycle through the functions with the mode button. Reading the manual will save time in learning how to use the various features, but most are fairly intuitive. The band is comfortable. I cannot speak to the longevity or water resistance of this watch.
