Hello,

I'm new to this forum, but have been skulking around other watch forums for years.

This is a watch you won't see much of:

This is the Astrodea, an astronomical, quartzwatch made by Citizen. Every year, Citizen introduces a new theme for the watches, which are designed by a Japanese astronomer. 500 of the blue dial version, are released yearly. 200 of the yellow version are released per year, but for distribution in Japan only.

This particular watch is a planisphere watch, depicting the Northern Hemisphere from latitude 35 degrees N (Tokyo). The dial rotates independantly in sidereal rate, which is about 24 hours. The chapter ring is user set to the appropriate time and date. From that setting, the dial will show the positions of the constellations at any time. The watch comes boxed with a huge user manual, which unfortunately, is entirely in Japanese, and a 10x loupe. Click here and look at the top of the pageto see an animation of what this watch does: http://www.astrodea.jp/

The last pic below, shows you the constellation Orion, through the loupe.
