Comments: This is an excellent watch while it works. I've had two or three of these over a course of 5 years, the first one worked for 3 years without failing. As others mentioned, the large display is quite handy. I especially liked the split function because in the end, that is the most crucial element to keep track of during a workout. I returned to this website again to buy another watch after the previous has failed but decided otherwise. The fact that the all of the 3 watches did fail after a while(even after battery replacement) seriously made me question whether I wish to invest in another, even despite its low price. A watch is akin to running shorts, one expects them to work 7 days out of the week, whenever one puts it on. Unfortunately, it failed in this regard. Also, I often found my timer restarted or continued to run after it's Start button was pressed in the bag. Often it would run for almost 24 hours which severely drained the battery. On a side note, if you are a non-recreational runner in high school or college on a tight budget, don't look further, just get this watch. It isn't a fancy Garmin but again, neither are your 1 inch split shorts.

Comments: I agree with the other reviewer. The ideal running watch. Because of the large face, all watch functions are easily readable. The "flick" feature, which I initially thought was a gimmick, is actually quite useful as it allows turning on the light with a flick of the wrist and without having to use the other hand. That means no disruption of your running rhythm when you want to check the time at night. I like the interval timer a lot. It's not fancy, but for my purposes - I run 17 min and walk 3 - it's enough. Each interval is announced with a series of clear beeps. The watch tells you at all times which interval you're in and how many overall interval cycles you've gone through. And unlike the Galloway run/walk counters, its waterproof.

Comments: For me, this remains the best running watch. Simple to use and Timex reliability. I liked the looks of my past, sleek version better and this model's band holder is a bit loose. Other brands (such as Soleus) are also misleading about the number of interval timers. This watch only has ONE interval timer. The interval timer has nine segments, but there are not nine, independent interval timers (unfortunately).
