The solid stainless steel caseback bears the serial number 40312857 alongside faintly visible original factory engravings. Movement Powering this timepiece is the ingenious Citizen Jet automatic movement, renowned for its geared outer ring rotor. This unique oscillating weight runs along the periphery of the movement, producing a characteristic winding sound and allowing for a thinner movement profile. The movement is clearly stamped with "CITIZEN JET," "AUTODATER," and "TWENTY ONE 21 JEWELS," showcasing its mechanical pedigree. Performing well within expected vintage tolerances; running strong and steady. Timegrapher results indicate 17s+25s/day.

Dimensions Case Size: 39 mm (excluding the crown) Remarks The Citizen Jet series holds a special place in the hearts of vintage Japanese watch enthusiasts. The combination of the oversized 39mm case, the elegant fluted bezel, and the mechanically fascinating ring rotor makes this Auto Dater a highly collectible and wearable piece. It is a testament to an era when watchmakers were boldly experimenting with automatic winding technology. History During the 1960s, the race to produce thinner, more efficient automatic watches led to incredible innovation. Citizen's answer was the Jet movement, featuring an outer ring rotor rather than a central oscillating weight. This design allowed the movement to be remarkably thin while maintaining excellent winding efficiency. The "ParaWater" designation was Citizen's proprietary terminology for water resistance, marking their early achievements in creating robust, everyday timepieces. Today, the Jet line is remembered as one of Citizen's most creative and beloved mid-century achievements. / Second Vintage SKU: CIT-CFP-0001
