I originally wanted a G-Shock but I have a small wrist and G-Shocks come with cases that are too big for my 6.1 inch wrist. An alternative? I bought the Timex Ironman. It has a rugged look and many of the features of a G-Shock but at a lower price. Small wrist? Or don't want to spend the money for a G-Shock? This is your best bet.

GREAT sports watch! TERRIBLE DELIVERY!!!

Color: Black/Digital/Green, Color: Black/Digital/Green

I am a Big Fan of TIMEX and I own several models, this one is my all time favorite. I've ordered it with so much excitement, but received an opened package, opened box, that was torn and destroyed, my Timex hanging out of the box!!!!!!!!!! COME ON People - We are paying our sweat money for this, at least deliver it with respect! The watch is a work of art and I love it! It's a good value for money, great in size, fits right on your wrist, feels so good, looks so cool and is super accurate! So, Thank you TIMEX ! I wrote 4 Starts because of the terrible delivery service!!! Not the watch! AMAZON - Please be respectful.

Simple and reliable

Color: Black/Digital/Green

I love the simplicity and reliability of this watch. It has only a handful of features, but they're all easy to figure out and use. The display is quite readable as well, under just about any conditions. This is an example of good design that doesn't try to do too much. What it does do, it does well. Good price too! These watches are durable and will last a long time. Battery changes are easy too.
