Great watch
Color: Green
This watch is two times the price of the he casino watch but it is so much better. The indigo dial lights up completely from all angles. It is easy to read even in 0 light. Much more durable and runs on 1 battery instead of 2 batteries in the Casio. Can’t go wrong with this watch!!!

First watch was defective, Replacement is great
Color: Green
It says indiglo on the watch face but there is no illumination what so ever. Totally useless in the dark. I exchanged it for a new one and it is perfect. Just what I expected. I can't speak to its accuracy yet, but it looks and feels great. The bezel doesn't move if that is important to anyone, but I don't think anyone is taking this scuba diving.

Worth it
Color: Orange
Excellent for the price. The indiglo is highly visible as a backlight. It's simple and no frills. The band is better than I expected. I gave it 4 stars because it's only water resistant to 100m or 10ATM and the adjustment/indiglo button isn't flush with the case. Overall Excellent choice for an outdoors watch.

Former reputation is not present in this watch.
Color: Orange
The bezel does not rotate, hand movement stops intermittently. Leaving you to correct the time frequently. Not worth the purchase, Timex is not it what it use to be. "It does'nt take a licking, cause it stops ticking."
