In addition to a solid deal on the Citizen Promaster Diver, Amazon is offering another big discount on a solar-powered tool watch, the Promaster Nighthawk. The Nighthawk is a solid pilot’s watch, featuring a solid 42mm case, lume’d indices, a rotating slide-rule bezel and a second timezone display at the center of the dial. It’s even rated water-resistant to 200 meters. Usually, the watch retails for $200, but right now it’s only $140.
