Not easy to get refund
I bought this for a watch. When it broke about 2 months in they told me to contact the Timex seller and ask them to help. I feel like it should have been a pretty simple "look at my broken watch." "oh, sorry about that but you bought insurance so here's your money" but it was not that. In the end I just bought a new watch because they made it too difficult to get help. Don't waste your money on the insurance.

Very Good watch
Color: Blackout
The one complaint I hear most often about this watch is it is harder to see in lower lighted conditions. Yes that is true BUT IT HAS INDIGLO so It is not a problem. Most of the time you don't need to turn the light on though. You usually can make out what it says even without the light. Usually if you can't see it then a slight angle change and you can see the time. If you still can't see it....it does have indiglo. It really takes no time at all to hit the button and you can see in any light condition. I have been looking at watches to buy for some time now and have looked at a lot of them. When I first got this in the mail I thought it to be small. I was comparing it to the G-shock series. The ones I was looking at the most was the XL ones. So yes it is small compared to the XL G-shocks. I have an XL watch and found that it gets in the way. When ever my wrist gets bent backwards my hand presses against the watch and restricts my movement that way. This is really the perfect size. One common complaint with Ironman's is they have started integrating the band with the watch. So when the band breaks, which they often did, the watch was useless cause you couldn't replace the band. This one has the replaceable band but still manages to have that integrated look, very nice. I really don't expect the band to break any time soon though. It feels very durable and thick. One thing about the band that I really like is at the end of the band. It has two little "nubbins" that lock in the that loop that holds the excess band in. They really work well. Every watch I have ever owned that little loop moves and releases the excess and then you have to fix it. It has yet to slip off once. All in all in is very nice watch. It works well, the price is very reasonable, The band is replaceable and durable, and the blacked out look is very nice. I love this watch.

Favorite daily use watch
Color: Blackout
Literally the best watch ever. Super durable. This is my second or third one. The Battery will last years at a time and doesn't take an expensive battery. The buttons are laid out intelligently and are intuitive to use. The strap will eventually break before the watch itself will. Though it has all the stop watch features, it's not too bulky. Also, it takes the time easily and keeps it.

No complaints after use
Color: Black/Yellow Accent
Always been a fan of Ironman watches especially the original. The negative display threw me off for a few days but getting used to it. Love the fit and size of it. Not to mention it's extremely light and you barely notice it after a bit. For under $40 if it malfunctions in a year or two I'll just buy another or one similar.
