Campanola 501 Watch by Citizen CTY57-1071 Moonphase

Beautiful Campanola Watch. Chronograph Solar Eco-Drive with many different functions and features. I received it as a gift about 15 years ago and never wore it. With box and all papers and cataloge. I'm not too sure, but I was informed that it is considered as a collector item as they made only 500 pieces, and this one is stamped with No. 234
