Second watch died faster than the first!
Color: Black/Brown/White
Now I have bought two of these. On the first, indiglo died after one year (battery otherwise fine). On the second, it only lasted 9 months. I’m done. On the first, suspecting the battery was prematurely drained, I took it to the jeweler to get a new battery. He said there was nothing wrong with the battery. I was within the warranty period for the second watch. When I inquired, I was told that it meant shipping the watch overseas for about 3 months to be fixed. Wow. So in reality, it's a disposable item that is not likely to work as long as warranted, much less several years. Time to find another brand.

An excellent replacement for the old camper watch
Color: Black/Black/Black
I wore Timex camer watches for much of my adult life. I prefer the analog wind-up versions, but they are not widely available at a reasonable price. I purchased this model for its large easy to read face and durable strap. The Indiglo feature is a bonus.

Favorite watch / solar
Color: Green/Green
I'm partial... I have bought Timex my intire life, they no doubt make the best watches... They take a licking, but keep on ticking is there old commercials.. True.. Great quality, keeps going after many year's... I never bought a solar watch from them prior I have to mention... It should hold up I'm thinking like their battery watches, I hope so. My favorite watch, I own a handful. Watch looks better in person... Downfall, they are trying a new band out of recycled plastic, I don't like it as much as the older bands it's soft, but feels a little strange...

Solar powered
Color: Green/Green
Great watch for us older folks. The hands are large enough to see easily and the fact it is solar powered means batteries do not have to be replaced every year or two.
