Dial and Hands The dial is the absolute highlight of this timepiece, featuring a deep charcoal sunburst finish that plays beautifully with the light. It is framed by a striking light blue and grey block-style minute track ring, giving the watch a unique depth and character not often seen in standard models. The signature day window is positioned uniquely at nine o'clock, while the date sits at three, creating a balanced horizontal symmetry. The applied silver baton indices and hands remain sharp and highly legible, showing only minimal signs of aging, while the text remains crisp and white. Case and Crystal The stainless steel cushion-shaped case remains in impressive condition, retaining its original lines and defined edges. It measures a versatile 36mm, offering a substantial yet comfortable presence on the wrist. The surfaces show light handling marks consistent with careful usage over the decades, preserving its vintage honesty without significant dings or deep scratches. The hardened mineral glass crystal, the namesake of this series, is clear and allows for an unobstructed view of the detailed dial. The crown is tucked neatly into the case profile. Movement Powering the watch is a high-grade Citizen 27-jewel automatic movement, a specification that placed this watch in the upper tier of Citizen's offerings during the era. The movement is clean and visually appealing through the open caseback photos, featuring a decorated rotor. It is currently running within vintage tolerances, with timegrapher results showing approximately 13 seconds per day, which indicates a healthy movement offering reliable vintage performance. Strap The watch is fitted with a black leather strap featuring white contrast stitching, which complements the charcoal dial and white indices perfectly. It is secured by a steel pin buckle and is supple, comfortable, and ready for immediate wear. Condition This timepiece is in excellent vintage condition. The dial is remarkably well-preserved with no spotting or staining. The case shows only minor surface wear without significant dings or scratches, maintaining a sharp profile.

Remarks This Citizen Crystal Seven Custom is a fantastic representation of the Space Age design language that influenced Japanese watchmaking in the late 1960s. The combination of the "Seven" automatic reliability, the "Crystal" glass durability, and the "Custom" unique design flair makes this a highly desirable piece for collectors. The distinct blue minute track and day-at-nine layout set it apart from the common dress watches of the period, offering a playful yet sophisticated look that is becoming increasingly difficult to find in such clean condition. History Introduced in 1965, the Citizen Crystal Seven series was named for its use of hardened mineral glass crystals rather than the standard acrylic, marking a significant advancement in scratch resistance. It became one of Citizen's best-selling automatic lines, directly competing with domestic rivals by offering high jewel counts and innovative designs. The "Seven" traditionally refers to the seven visible features of the watch or the day of the week, and these watches are now celebrated for their robust build quality and distinct mid-century styling. The "Custom" line within the series allowed Citizen designers to experiment with more colorful and unconventional dial layouts, resulting in some of the most collectible vintage Japanese watches today. / Second Vintage SKU: CIT-CCS-0007
