Up for sale is an ultra-rare vintage Citizen Vega Cosmosign Disk Time men’s planet watch, reference 4A31-409299, produced for the Japan Domestic Market (JDM) during the 1980s. This model is one of Citizen’s most imaginative and unconventional designs, featuring a cosmic disk-style time display with an extremely unique rotating planet seconds indicator, making it one of the most visually striking watches of the era. The watch is being sold for parts and repair. A battery was inserted, however the watch is currently not functioning and has not been tested beyond that point, so the exact issue is unknown and it is not known whether it can be repaired. This listing is intended for collectors, watchmakers, or restoration projects. The watch is fitted with a leather strap that appears to be original, however this cannot be stated with absolute confidence. Aside from this uncertainty, the remaining parts of the watch appear to be original. The watch is in very good physical condition overall, showing signs of use and age consistent with a genuine vintage timepiece. The photos best describe its physical condition and should be reviewed carefully.
