Case Design: The Iconic 62GS Modern Reinterpretation
Launched in 1967, the 62GS was Grand Seiko’s first automatic movement. This timepiece gained popularity for its striking design featuring a mirrored, multi-sided case and wide dial opening, which was achieved with bezel-free construction and Seiko’s signature Zaratsu polishing technique. Pure, refined, and noble, the 62GS is a treasured classic.
Movement: 9S85 calibre from the Shizukuishi Watch Studio in Iwate Prefecture. This sophisticated, modern movement makes use of innovations to its mainspring, hairspring, and escapement to improve precision. The movement demonstrates the
pure power of the Mechanical Hi-Beat 36,000.
Kunpu, the refreshing breeze
As spring passes to summer, the land turns lush and green. A refreshing summer zephyr blows over waving fields and grass. This refreshing zephyr in Japanese is kunpu. This model’s rich, green dial seizes a summer moment to enjoy forever.
It is during this season that rice is sowed (Bōshu) and when the night is shortest (Geshi). As the intensity of heat raises (Shōsho), summer ends with the hottest day of the year (Taisho).
Caliber 9S85 uses sophisticated modern technology applying innovations to the precision controlling mainspring, the hairspring, and the escapement. Together the movement showcases the pure power and dynamism of the Mechanical Hi-Beat 36,000.
Unveiling its deep sensibilities and a reverence for the Japanese passage of time, Grand Seiko has reimagined the iconic 62GS design with four new timepieces for its Heritage Collection.
