This is another one of the Trans Solar watches by Citizen under the Trans Continents range.
Trans Solar is the the name for Eco-Drive watches under the Trans Continents range, and so does not need batteries.
This watch was made in 2005, and is a three hand dial watch with day and date. The solar panel is on the watch face (rather than being incorporated into the glass). It is a very lightweight watch as the case is made of Aluminum.
It uses an E001 module (the instructions can be found at link), and has a full model number of E001-S027764.
