Celebrating the vernal equinox with Shunbun

One of four timepieces in the Japan Seasons Collection, exclusive to the USA

When sakura blossoms fall into water they swirl and float, appearing to dance atop the water. The Japanese call them flower rafts, or hanaikada. Pulling its inspiration from this tranquil scene, the SBGA413 dialwith its unique texture, subtle coloration, and mesmerizing shimmerevokes the spirit of the fleeting sakura season.

The case design also pulls inspiration from a distinct source, this time from Grand Seiko's history. Launched in 1967, the 62GS was Grand Seiko’s first automatic watch. This timepiece gained popularity for its striking design, which featured a mirrored, multi-sided case and wide dial opening made possible via a bezel-free construction. The contemporary interpretation of the 62GS design can be seen here. 

Powering the watch is Caliber 9R65, a sophisticated Spring Drive movement assembled at Shinshu Watch Studio. Emblematic of Spring Drive, the second hand glides around the dial, reflecting the continuous flow of time itself. The decorated caliber can be enjoyed through the exhibition case back.
