► SELLER'S DESCRIPTION
Up for sale is a NOS rare vintage Citizen Cosmotron 7802-870140 men’s electronic dress sports watch, produced for the Japan Domestic Market (JDM) during the 1970s. The Cosmotron series was Citizen’s pioneering electronic tuning fork watch line, celebrated for its innovative technology, smooth sweeping seconds hand, and distinctive futuristic styling. This particular example is one of the rarest and most sought-after models in the Cosmotron series and remains in mint, never-used condition.
The watch is being sold for parts and repair. It is currently fully functional when positioned face up; however, when the watch is turned upside down or held at steep angles, it stops running. It will require a service in order to operate properly.
All parts of the watch are original, including the original Citizen signed stainless steel bracelet. It also comes complete with its original hangtags, one of which doubles as the original instruction manual.
The watch is in mint, never-used physical condition with only light signs of handling and age from decades of storage. The photos best describe its physical condition and should be reviewed carefully prior to purchase.
