Here is a unique wristwatch, I think. It comes from Citizen, which is a fine maker of watches, and is part of their Astrodea collection. The watch gives you a view of the heavens as seen from the Northern Hemisphere and it rotates in real time. The face shows 1,109 stars and 169 cluster galaxies. (I would hate to have had the job of actually counting them from the watches face). “It also includes other measurements like equinox indications, constellation markers, location of the sun, solar position, sunrise and sunset times and the daily duration of sunshine.”
Colors are either a blue or gold face, and it has a stainless steel case. Because of the detail of the face, it also comes with a 10x magnifier. Its cost is about $585.
