60th Anniversary Limited Edition

Grand Seiko SLGH003

The Grand Seiko SLGH003 – 60th Anniversary Limited Edition celebrates the brand’s heritage through the debut of the revolutionary Calibre 9SA5, presented in a refined 40 mm stainless steel case with a striking blue sunray dial. This Hi-Beat masterpiece blends exceptional precision engineering with meticulous Zaratsu polishing, setting a new benchmark in contemporary mechanical innovation.

The elegantly proportioned case features a low-set crown for improved ergonomics and a dual-curved box sapphire crystal with anti-reflective coating. Through the sapphire exhibition caseback, the beautifully hand-finished movement is revealed, complementing the dial’s sharp applied indices and faceted hands for exceptional legibility and depth.

At its core beats the in-house Calibre 9SA5, an automatic movement with manual-winding capability, incorporating the patented Dual Impulse Escapement, twin impulse wheels, a free-sprung balance, and MEMS-fabricated components for superior energy efficiency. Operating at 36,000 vibrations per hour (Hi-Beat), it delivers an impressive 80-hour power reserve while achieving chronometer-grade accuracy of +5/-3 seconds per day.

Limited to 1,000 pieces, this reference appeals to collectors who value Grand Seiko’s fusion of artisanal craftsmanship, cutting-edge horology, and restrained elegance.
