GRAND SEIKO

HERITAGE RIKKA (SUMMER) SBGH351

$7,500

The deep green dial evokes the sights and sounds of Rikka, the seventh of Japan’s twenty-four sekki or seasons. Spring has passed and the increasing warmth of the sun's rays announces that summer has begun. Japan’s plants take on a deeper green hue and, as they grow, sway elegantly in the early summer wind.

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 through 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 Caliber 9S85, hand assembled by the skilled craftsmen and women of the Grand Seiko Studio Shizukuishi. The vibrant green coloring evokes the gentle breeze that passes through the lush grasslands near the studio. The GS logo and the seconds hand provide a pop of gold coloring that harmonizes with the green backdrop of the dial.

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.
