I absolutely love my Timex Ironman watches. I have had many over a very long period of time. Wonderful set of functions for the price. Very affordable. Easy to use. Lasts a long time. Very easy to read in standard lighting. I like the Indiglo when needed, but do not use it too often. Absolutely love the ability to set a repeat timer to remind me to do something at a fixed interval, or to keep me on task for a fixed period of time. Great to be able to set three independent alarms. Potential to capture a huge number of splits with the stopwatch. I purchased this watch to replace a similar model with a dead battery. I have replaced batteries in the past, but it is quicker and easier to buy a replacement watch. I am saving my old watches for that day in the future when the Ironman model may no longer be available. I expect this will be my watch of choice for the rest of my life.

Just fine if you have simple needs...

Color: Black/Digital/Black/Green

Exactly what I needed: a cheap, durable wrist watch. The only thing it was lacking were instructions, but about 5 minutes of messing with the buttons got it set up
