It is an automatic-only collection that appeared in 1961 as CITIZEN's first full-fledged men's automatic watch. It is equipped with the "Jet Rotor," an outer-ring ball bearing rotor function, and was popular at the time because the sound of the rotor spinning when the watch was shaken resembled a jet engine. This individual is a particularly rare 20-micron C.G.P. square case model. The dial is silver sunray. It features applied bar indexes and edgy dauphine hands. A practical date display at the 4:30 position. A stylish design with the Jet mark lit up at the 6 o'clock position. The SS bracelet is also a valuable CITIZEN genuine original bracelet. It is a masterpiece of a Japanese-made wristwatch from CITIZEN, packed with the charm of vintage watches. ● It is an unused deadstock item. Although there are slight scratches on the case from long-term storage, there is no damage, and the windshield, dial, and hands are in very good condition, making it a very beautiful condition for an antique watch of this age. The engraving on the back cover is also clearly visible. Please check the photos. ● Upon listing, I checked the operation, and it is running vigorously when wound by shaking the watch. The daily difference is about ±1 minute on a timegrapher flat position. (This does not guarantee accuracy. The daily difference may vary depending on posture changes, usage conditions, the remaining amount of the mainspring, and other factors, so please consider it as a reference) ● There may be scratches and stains that cannot be fully captured in the photos. Also, the evaluation of the item is my subjective opinion, so there may be individual differences. Please consider it by referring to the content description and photos. ● Shipping will be done as quickly and carefully as possible.
