Historical & Collector’s Note
Citizen’s Hi-Beat Era
During the late 1960s and early 1970s, Citizen introduced the Leopard series as one of its premium mechanical collections. Equipped with 28,800 vibrations per hour, these Hi-Beat movements provided smoother seconds-hand motion and improved timekeeping performance compared to conventional 18,000 or 21,600 BPH calibers.
Striking Deep Blue Sunburst Dial
One of the defining features of this reference is its deep blue sunburst dial, which transforms dramatically under changing light. The combination of the radiant finish, applied faceted indices, and polished hands creates a level of visual depth that has made blue-dial Leopard models especially desirable among vintage Japanese watch collectors.
Well-Balanced Vintage Proportions
With a 37 mm case, 42 mm lug-to-lug, and an 11 mm thickness, the Leopard offers a versatile wrist presence that feels substantial without sacrificing comfort. Its timeless proportions make it equally suitable for everyday wear or as part of a curated vintage collection.
