Astronomers working with huge telescopes have all of the equipment they need to tell them when the conditions are ideal to stargaze. But it’s not so easy for hobbyists, who have to use and set up their telescopes in the backyard in order to gaze out at the heavens. This watch will give them all the data they need.

The LCD display on the face has 96 separate sections arranged in a ray pattern. Each slice represents a 15 minute window of time, which adds up to a full 24 hour day. Just choose your location from a list of 583 pre-programmed cities. The sections are shaded to depict the hours of sunlight and darkness throughout the day. Then another circular LCD display around the edge shows the times of moonrise and moonset. And yes, it can tell the time too. It will cost you $495.95, but will come in very handy.
