Great watch for the price
Color: Tan/Tan/Tan, Color: Tan/Tan/Tan
Great looking watch. The band material feels really comfortable and long lasting. Only problem I have with it is that the second hand is slightly off when aligned to the 12. Not a huge deal just a minor detail

Long time Timex ironman digital owner. First analog watch I've owned in a long, long time. LOVE IT.
Color: Black/Black/Black
Long time Timex iron man digital owner. First analog watch I've owned in a long, long time. LOVE IT. I don't know I'd go swimming or kayaking with this -- might be fine -- but for "dry land" this is a great watch, good band, for a reasonable price. It's battery powered, but that's OK with me.
