Then you have the newer Astrodea Moon Phase watch

The next step up is the Citizen Campanola versions of the Astrodea which are the Cosmosign watches (which according to the chart below actually were released before the current Astrodea line). This takes everything you love about the Astrodea watches and the quality of the Campanola line and puts them together. This is really the best of both worlds for me. You can see the impressive level of detail on the dial using all the Campanola charm. The blue star map rotating dial just looks so beautiful. Two versions are available in a round or tonneau shaped case. These models again are also very rare, but findable. These watches you can get for roughly double the price of the base Astrodea watch line. The chart below makes it a bit confusing as to when the Astrodea name actually came out. "Lighthouse" was apparently the name for Citizen celestial watches until recently. The newest Astrodea watches (you can get a glimpse of them in the chart at the bottom) that have a different case and bracelet design, but with what I think is the same face. There you have it, about as much as I can muster up about the Astrodea collection without my mind going 'orbital.' It is really a fascinating collection as I previously expressed, but not a watch for everyone. Though if you are one of the people who is taken by this concept, you'll know it immediately and have probably already decided that "one of these watches will be mine!"
