Grand Seiko Pays Tribute to the Nature of Time and Japan’s Twenty-Four Seasons with Four New Timepieces in its Heritage Collection.

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.

The new watches celebrate The Nature of Time and commemorate Japan’s twenty-four sekki*  that mark nature’s ever-changing seasons. The sekki offer a poetic journey as nature awakens, blossoms, matures and settles into slumber from the beginning of spring, known as risshun, to the glistening cold of winter known as daikan.

Four of the Twenty-Four Sekki

Taisetsu: The Deep Snow of Winter
Pine trees crusted with snow, silent under the sun of winter. It’s when the world has settled into a slumber only to awaken in the spring. This model’s dial celebrates the winter snow as it gathers and glitters against the sunlight.

Shunbun: The Vernal Equinox
When sakura blossoms fall into water, they swirl and float. The pink blossoms dance on the water, and the Japanese call them flower rafts, hanaikada. The pink dial of this model captures the spirit of the fleeting sakura season. 

Rikka: Early 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.  

Shubun: The Autumnal Equinox
Under the moonlight, the night is quiet except for the last of the chirping crickets. The bright moon against the dark sky in Japanese is known as tsukiyo. The dial of this model is a dark blue to celebrate the autumnal equinox and represent the autumn clouds as they float through the sky.

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.

Movements: The Twin-Peaks of Grand Seiko
The four models feature two characteristic Grand Seiko movements, with each assembled by hand by highly skilled craftspeople. 

Shunbun and Taisetsu-the vernal equinox and the deep snow of winter?house the 9R65 caliber that Grand Seiko assembles in its Shinshu Watch Studio, located in Nagano Prefecture. This sophisticated movement combines modern technology with the skilled hands of master craftspeople for its fine adjustments and high precision. The Spring Drive movement further reflects the smooth passage of time with every revolution. 

Rikka and Shubun-early summer and the autumnal equinox-house the 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.
