This timepiece is a magnificent artifact from 1952, marking the dawn of complicated watchmaking for Citizen.The reference 1505 is the technical foundation of Japan’s first domestically produced triple-calendar wristwatch, a feat that challenged the Swiss giants of the era.It is powered by the rare 16-jewel Caliber 59, a low-beat manual-wind movement featuring a sophisticated add-on calendar plate that displays the day and month in twin windows and the date via a beautiful light-blue pointer hand along the outer track.
The architecture is quintessentially 1950s executive luxury, utilizing a 14k gold-filled case with sharp, elongated lugs and an ivory sunray dial that has aged with a stunning, honest patina.The dial is a masterclass in balance, featuring applied gold "C" logos and faceted hour markers, with the day and month wheels displayed in traditional Kanji, definitively confirming its authentic Japanese Domestic Market (JDM) heritage. At a time when this watch cost more than a university graduate's monthly salary, it was a bold statement of status and engineering prowess. This is an essential acquisition for an elite collector who appreciates pioneering technical history, the mechanical soul of a 1950s heart, and the rare, complex presence of the first Japanese triple calendar
