Great Multi-Function Watch
Color: Gray/Digital/Gray
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
