A great watch
Color: Black/Gray
It's a Timex! Inexpensive, accurate and rugged. I use it as a watch. I play golf and did not want a watch with a stem on the right side. This is the third Ironman I have owned and so far all the batteries have outlasted the straps. The strap on this one appears to be a bit more rugged than the last one so hopefully it will last at least 5 years. Seven dollars per year is a pretty good deal for this accurate and rugged watch.

Beautiful Simplicity
Color: Black/Gray/Black
I really love the watch. The shape of the hands is simple elegance. The white hands on the off-white face really pop in person.

Wears Big
Color: Black/Black/Blue
Watch wears a lot large than it stated size. Feels more around the 45mm dimension on the wrist.
