Calibre 9S 20th Anniversary Limited EditionMechanical Hi-Beat 36000 Grand Seiko Special Standard Model A Mechanical Hi-Beat 36000 features only a special movement that passed the Grand Seiko Special Standard test, which imposes more stringent precision criteria on itself than the normal 9S Mechanical movements. As a symbol of the movement that passed the high precision criterion 'accuracy (when static) : +4 to -2 seconds per day', the word 'SPECIAL' is inscribed on the dial, and the Grand Seiko lion emblem in 18K yellow gold on the oscillating weight can be viewed through the see-through case back. The radial spiral pattern on the dial consisting of 80 spun curved lines is an original insignia adopted for the 20th anniversary limited edition models of the 9S Mechanical calibre and embodies the Grand Seiko spirit connecting the path of history it has followed to the future. The 'G' and 'S' of Grand Seiko and the 'S' mark of Daini Seikosha (currently Seiko Instruments Inc.), which produced the first 10-beat watch, '45GS' are regularly arranged. Features the clean edges and distortion-free mirror surfaces that only Grand Seiko’s Zaratsu polishing can deliver. Smooth curves are added to the beautiful three-dimensional structure characteristic of Grand Seiko style for a graceful profile. The elegant shimmer of 18K yellow gold case and the dark brown crocodile leather strap embrace the refined dial design, marking the passage of high quality, sophisticated time.  Available exclusively at the Grand Seiko Boutique.
