"Yuka Momiji"

In Japan, an appreciation for the changing seasons is woven into the fabric of daily life. Grand Seiko celebrates the ebullient reds of autumn with its latest creation, the Hi-Beat 36000 GMT SBGJ273. With its red striated dial, this watch calls to mind the way lacquered wooden floors in a traditional Japanese building reflect the leaves of outside maple trees, expressing yuka momiji.

The SBGJ273 comes in a classic case shape from the Elegance Collection that was influenced by the very first Grand Seiko watch from 1960. Its rounded case and raised box-shaped crystal ensure mid-century good looks, while a gold-colored GMT hand adds to the feeling of autumn.

The Hi-Beat 9S86 movement uses MEMS for escapement parts and Spron alloys for the mainspring and hairspring. This movement provides excellent rate stability, accuracy to +5/-3 seconds per day, and resistance to shocks while maintaining a power reserve of 55 hours when fully wound.
User Manual


This high-specification movement delivers the same accuracy (+5 to -3 seconds a day) and the same power reserve (55 hours) as the core Caliber 9S85, while also offering the GMT function that the international traveler needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed. The GMT hand shows the time in the home time zone.

Pulling the crown out by one notch enables the hour hand to be adjusted without stopping the seconds hand so that the highly accurate timekeeping delivered by the Hi-Beat 36000 is not lost. Caliber 9S86 is the embodiment of the Grand Seiko ideal of high accuracy, maintaining exceptional precision in both the essential time of day display and the GMT function.

A "Tough" GMT powered by 9F​

Featuring Grand Seiko's distinct "Tough" Sport case design and highly accurate 9F86 GMT caliber, SBGN019 is the perfect grab-and-go watch for any adventure.

The stainless steel case features 20 bar of water resistance and has a magnetic resistance rating of 16,000 A/m (approx. 200 gauss), which is roughly three times the more common 4,800 A/m rating (60 gauss). The angular design of the case is highly ergonomic, and features an eye-catching blend of Zaratsu-polished and hairline-finished surfaces.

The black dial features bold, highly legible elements, from the contrasting color details and date window at four o’clock, to the sizeable indexes, hands, and their respective use of Lumibrite—a long-lasting, proprietary luminous paint that ensures nighttime visibility. A black ceramic bezel marked with a 24-hour scale frames the dial .

Powering the watch is Caliber 9F86, a quartz caliber with a GMT function, a robust build, and an impressive accuracy of +/-10 seconds a year.
