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.

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.
