I purchased this watch knowing Timex's history of reliability, ease of use, and sturdiness.  With the T5E231 Ironman everything is amplified: bigger size, more functions, more pretty (prettier, I know :)

Depending on your preference, the size of this watch may either be too big or just right.  For me, despite my small wrists (I'm measure 6' tall), the Ironman fits just right; I like how it comfortably sits on my wrist (not weighing too much, in fact, it's pretty light).

It has more functions than I actually need.  Unlike most folks who will purchase this watch for its running pedigree and primary purpose (with lap times, etc.), I use it for more staid reasons, such as: keeping time, chronometer, timer, and alarms (plural).  To my surprise, this watch has 5 alarm settings (my older Ironman had only 3).  The additional alarms are actually quite useful as I can program them for different reasons: one to wake me up during the week, another to wake me up on the weekends, another for reminders for daily medication consumption.  Lastly, each alarm has its own musical tone so as to distinguish it from the other alarms.

Because of its size, the watch face is nice and large.  I can easily and quickly see everything: time, date, and day.  The buttons are easy to push for additional feature access.  And, as usual, the "Indiglow" light feature is awesome.  This model has a "cool" LIGHT BLUE hue when on; I can easily see it in the dark of a movie theater without disturbing anybody around me.

All around this is a great, practical, very useful, every-day watch.  I'm sure I will enjoy it for years to come.
