Great casual watch
Color: Blue/Blue/Blue/solar
Has become my casual weekend watch. Can easily swap out the bands with no issue. I love that I no longer have to replace a watch battery.

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.

Disappointing
Color: Black/Black/Black
Overall the watch is ok. The price doesn't reflect the quality of the watch. This should be a $20.00 dollar watch. I purchased this partially because I thought the number would glow at night, they do not. The hour and minute hand barely glow at night. I decided to just keep it, rather than returning it, and now I wish I had just returned it. After 2 months, I got a scratch on the watch, what looks like cheap, plastic. I can't say I would recommend it for that reason, I'm a average field watch wearer, which means they have to be somewhat durable. This was disappointing.
