1992 - Citizen Butterfly
The case and band have an odd, integrated design. It has been called a “butterfly” or “four leaf clover” design because of the shape of the four solar panels. They are rounded on the outer edges but converge in the center with a square edge. Model CO30-087909 K 20800516 GN-4-S
Comment: One of the most original and least attractive solar watches made.
Another example is the C030-089626 K 30701056 GN-4-S. A round set of hour and minute markers are printed on the crystal, framing the hands and making the analog time easier to read than on the “Butterfly” model. It has a second hand. (The band is not original on this example.)
