We recently told you about the Astrodea astronomy watch. 
ThinkGeek offers another astronomy watch at a lower price-point. Enter the date and time on the planisphere dial to see a display of the night sky. The celestial display is accurate for 35-50 North latitudes. The watch has a brass face and a rubber and stainless steel band. The face is luminescent for 2-3 hours, so you can use it without needing a flashlight that wrecks your night vision. It’s about $50 from ThinkGeek.
