► SELLER'S DESCRIPTION
Up for sale is an ultra rare and highly desirable Casio Cosmo Phase CGW-50 men’s digital astronomy sports watch, powered by Module 830 and produced for the Japan Domestic Market (JDM) during the 1980s. This model is one of Casio’s most collectible vintage digital pieces, featuring its iconic cosmic/astronomy phase display with functionality spanning the years 1901 through 2200.
The watch is being sold for parts and repair due to damage to the case. One of the case lugs has chipped/broken, and as a result, a band can no longer be properly attached to the watch. The photos best show the extent of the damage and should be reviewed carefully. Some of the chipped pieces are included with the watch for any potential repairs or restoration.
Despite the case damage, the watch itself is in full working condition, and all features and functions of the watch are operating properly. It is being sold as is for parts, repair, or restoration due specifically to the damaged case lug.
The watch has visible signs of use and age, and the photos best describe its overall physical condition.
