Available now on auction by Second Vintage This is an exceptional opportunity to acquire a horological gem from the golden era of Japanese watchmaking, a timepiece that combines technical innovation with stunning aesthetic preservation. This Citizen Auto Dater 7 is a rare example featuring the legendary "Jet" movement, a unique peripheral geared rotor system that is highly prized by collectors for its distinctive sound and winding efficiency. Housed in a substantial 38mm gold-plated case with a sharp fluted bezel, this piece offers a wrist presence that feels surprisingly modern while retaining its vintage charm. The incredible condition of the dial and the sharpness of the case facets suggest this watch was treasured and rarely worn, making it a standout addition for any serious collector of vintage Japanese horology. Brand: Citizen Model: Auto Dater 7 Reference Number: ADSG 51301-Y Serial Number: 50800227 Movement: Automatic "Jet" Caliber, 25 Jewels Dial: Silver sunburst with day and date Case Size: 38 mm (excluding the crown) Case Material: Gold Plated (C.G.P.) Production Year: 1965 Condition: Near-mint condition. The watch appears exceptionally preserved with a flawless dial and crisp case lines. Timegrapher results show the movement running between +9 and +14 seconds per day, which indicates healthy movement performance. Dial and Hands The silver sunburst dial is preserved in breathtaking condition, free from spotting, staining, or oxidation. It features substantial applied gold faceted hour markers that catch the light beautifully, complementing the gold dauphine hands which are equally pristine. A distinct framed window at the 12 o'clock position displays the day of the week, while a magnified date window sits at 3 o'clock, both offering clear legibility. The applied "7" logo inside a shield emblem and the "Citizen Auto Dater" script remain sharp and crisp, with the "Para 40M Water" text clearly visible in blue at the bottom. Case and Crystal The oversized 38mm case is a defining feature of this model, finished in high-quality Citizen Gold Plate (C.G.P.) that remains thick and luxurious with no visible brassing. The fluted bezel is remarkably sharp, retaining its original definition without the softening often seen on vintage gold-plated watches. The lugs are thick and retain their factory geometry. The screw-down caseback is a work of art in itself, featuring a deeply embossed central medallion with the "7" and eagle shield motif, surrounded by crisp technical engravings. The acrylic crystal is clear and includes the original-style cyclops magnifier over the date. Movement Powering this timepiece is the celebrated Citizen "Jet" automatic movement, a 25-jewel caliber famous for its circular geared rotor. Unlike standard automatic movements with a central oscillating weight, the Jet uses a peripheral rotor that rotates around the movement, allowing for a thinner profile and creating a unique "swishing" sound when wound. The movement is clean and is currently running within vintage tolerances, with timegrapher readings between +9 and +14 seconds per day, suggesting reliable mechanics. Strap The watch is fitted with a high-quality reddish-brown leather strap featuring a lizard grain texture and contrasting yellow stitching. This choice of strap perfectly complements the gold tones of the case and the vintage character of the dial, offering a sophisticated look on the wrist. Condition This example is graded as Near-mint condition. It presents as a nearly new-like timepiece with exceptional preservation. The dial is flawless, and the gold plating shows virtually no signs of wear. Any surface marks on the case are extremely faint and only visible under very close inspection. It is rare to find a gold-plated model from the mid-1960s in this state of preservation. Dimensions With a case diameter of 38mm excluding the crown, this watch wears larger than many of its contemporaries, offering a desirable "jumbo" size that fits perfectly with modern tastes. The lug-to-lug length ensures it sits comfortably on a variety of wrist sizes. Remarks This Citizen Auto Dater 7 "Jet" stands out not only for its condition but for its technical significance. The Jet movement was a short-lived but significant innovation in Citizen's history, produced before the industry standardized on central rotors. Combined with the "Para Water" specification—Citizen's pioneering water-resistant technology—this watch represents the pinnacle of 1960s Japanese everyday luxury. History Introduced in the 1960s, the Auto Dater 7 line was Citizen's direct answer to the competition's sporting dress watches, targeting the young professional market with features like waterproofing, automatic winding, and day-date complications. The "7" branding referenced special features of the watch, similar to the "5" in competing models. The use of the Jet rotor movement dates this specific piece to the mid-60s, capturing a specific moment in horological engineering before the quartz revolution changed the landscape forever.
