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."
