Grand Seiko Four Seasons "Summer"

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. 

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.
