Grand Seiko SBGH273 Heritage

Celebrating the autumnal equinox with Shubun

Royal Jewelers is an authorized Grand Seiko dealer in the Boston area and offers the Grand Seiko SBGH273 Heritage with Grand Seiko's 5 year warranty.

Imagine a cloudy night with a bright moon against the dark fall sky. This scene, in Japanese known as tsukiyo, offers inspiration for the dial of the SBGH273. With its unique texture, subtle coloration, and mesmerizing shimmer, the dial evokes the autumnal equinox by representing clouds as they float through the autumn sky.

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 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.
