About this reference
The Grand Seiko SBGJ277 places a green dial and matching green bezel within the large 44.2 mm Sport GMT case. Its snow-valley dial pattern gives the broad steel design a changing surface, while sapphire crystal, LumiBrite, and 200-metre water resistance support the watch's active purpose. The solid back and substantial proportions keep it grounded as a robust traveller rather than a dressier GMT.
Inside, calibre 9S86 brings Hi-Beat 36000 performance to the GMT and date display. The 37-jewel automatic movement winds bidirectionally, uses a free-sprung balance, and stores 55 hours of power in one barrel. Its 36,000 vibrations per hour, six-position testing, hacking seconds, and stated +5/-3 seconds per day give the watch a distinctly high-frequency mechanical pulse without sacrificing useful time-zone control.
