GRAND SEIKO

HERITAGE SHUBUN (AUTUMN)

$7,500

The dial is inspired by the clear night skies that Japan enjoys during Shūbun, the sixteenth of the twenty-four sekki or seasons, which falls around the time of the autumn equinox. The gold-toned Grand Seiko lettering and seconds hand stand out in sharp relief against the deep blue dial, echoing the way the moon and stars illuminate the night sky.

This is a modern re-interpretation of the celebrated 62GS from 1967, whose characteristic sharp edges and perfect, distortion-free surfaces can only be created with Zaratsu polishing. The watch’s wide dial opening was achieved thanks to a bezel-free construction, lending the 62GS a distinctive appearance on the wrist.

Inside is the Hi-Beat automatic Caliber 9S85, hand-assembled by the skilled craftsmen and women of the Grand Seiko Studio Shizukuishi.

FEATURES

In 2019, Grand Seiko unveiled the Japan Seasons collection. That initial launch featured four watches — SBGA413 (Shunbun), SBGH271 (Rikka), SBGH273 (Shubun) and SBGA415 (Taisetsu) — each of them representing one of Japan’s twenty-four sekki (micro-seasons) that mark the progression of the four seasons. In 2020, Grand Seiko expanded the collection with two special edition timepieces (SBGA427 and SBGA429) exclusive to the United States and named after one of the twenty-four sekki known in Japan as Sōkō.

The Hi-Beat GMT 9S86 caliber runs at 36,000 bph, has a 55-hour power reserve, and an accuracy rating of +5/-3 seconds a day. Through the utilization of MEMS and through the development of Spron alloys for the mainspring and hairspring, Grand Seiko was able to create high frequency movements that could maintain a 55-hour power reserve while running at a high frequency.
