Key Features

• The Inaugural Founding Dawn of 56KS King History (1969): Manufactured in 1969—a landmark milestone year defining Seiko's mechanical zenith—the King Calendar reference 5625-7000 stands as the inaugural "first generation" pioneer that launched Suwa Seikosha's legendary 56KS series. Designed to represent the ideal balance of high-beat precision and ultra-slim executive luxury, this model set the standard for 1970s Japanese high-grade horology.
• The Legendary High-Beat 25-Jewel Caliber 5625 Engine: Powering this historic instrument is the inaugural 25-jewel Caliber 5625A, an in-house automatic engine operating at a swift high-beat frequency of 28,800 vibrations per hour (8 beats per second). Engineered to offer supreme regulation potential in a slim profile, this 25-jewel movement features hacking seconds, smooth manual-winding capability, and a quick-set date mechanism.
• Architectural "7000" Monocoque Case and Grammar of Design Geometry: Sourced in a solid stainless steel case, the reference 5625-7000 features a coveted front-loading monocoque (one-piece) case architecture with no traditional case back. Built strictly in accordance with Taro Tanaka's "Grammar of Design" guidelines, the broad sweeping lugs, razor-sharp Zaratsu-polished planes, and zero-distortion mirror facets deliver a low center of gravity that rests flush against the wrist.
• Immaculate Date-Only Dial Symmetry and Clinical Clarity: The dial of the 5625-7000 showcases clinical late-1960s visual restraint, displaying a radiant silver sunburst canvas decorated with hand-applied, multifaceted rectangular block indices with black center inserts. Free from day-window clutter, the neatly framed date aperture at 3 o'clock is perfectly balanced by the applied "KS" logo and "HI-BEAT" typography above 6 o'clock.
• The Sovereign Solid Gold KS Shield Case Back Medallion: The ultimate seal of prestige rests on the monocoque backplate: the iconic solid gold-embossed King "KS" shield medallion. Certifying its factory-regulated chronometric standards and historical status as a launch reference for Suwa's 56KS lineup, the 1969 5625-7000 King Calendar remains an essential, investment-grade cornerstone reference for collectors worldwide.
