Celebrating early summer with Rikka
As spring passes over to summer, the land turns lush and green. Pulling its inspiration from this scene, the SBGH271 dial—with its unique texture, subtle coloration, and mesmerizing shimmer—evokes these early moments of summer.
Powering the watch is Caliber 9S85, a sophisticated Hi-Beat movement running at 36,000 bph. This modern movement makes use of innovations to its mainspring, hairspring, and escapement to improve precision. Grand Seiko manufactures this movement at Studio Shizukuishi in Iwate Prefecture.

FEATURES
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.
