Nighthawk is rated 4.3 out of 5 by 14.
Rated 5 out of 5 by from Everything you want from a watch Since I purchased this watch it has been my "go-to" watch. I own about 10 watches and since I purchased this one, I can seem to want to wear any other ones. it's the perfect size and with a small bezel, the dial seems even larger than it is. Really well built. I can wear this watch to any occasion.

Rated 1 out of 5 by from Doesn’t keep time Followed the instructions to set it. The watch is not keeping time. I called Citizen customer support and they were not helpful or even polite. My options are to send a brand new watch to the repair department (not) or to return it, wait for my refund, and then re-order. What a pain.

How easy is it to see in the dark?

Asked by: Aviator
Impossible. Mine has zero lume on the hands, but the hour markers are lit up.
