Grand Seiko 4522-8000 Hi Beat

The Seiko Grand Seiko ref. 4522-8000 is a masterpiece of Japanese watchmaking, representing the pinnacle of precision and craftsmanship in the late 1960s. Released in 1969, this reference belongs to the celebrated 45GS series, developed by the Daini Seikosha division. It is powered by the hand-wound Caliber 4522A, a chronometer-grade movement with data quickset feature and beating at an impressive 36,000 vibrations per hour (Hi-Beat)—a technical achievement aimed at superior accuracy and stability.

The 37mm stainless steel case is sharp, angular, and finished with the signature Zaratsu polishing, embodying the essential "Grammar of Design" philosophy that still guides Grand Seiko today. The crisp silver sunburst dal is minimalist and elegant, with razor-sharp indices and dauphine hands that reflect the brand's obsession with light and legibility.

This particular example is in as-new condition, preserving its original geometry and factory finishing, and is paired with a refined black lizard leather strap, a tasteful nod to its vintage character. Collectors prize the 4522-8000 for its understated elegance and the technical prowess of its high-beat movement—a true expression of Grand Seiko’s relentless pursuit of excellence.
