About this reference
The SBGM001 gives its 39.2 mm stainless-steel case a quietly purposeful character through a black dial, restrained proportions, and 100-metre water resistance. Its travel display brings a second time zone and date into a compact Elegance profile, keeping the watch composed when the function is in use.
Grand Seiko's in-house Mechanical Caliber 9S56 is an automatic GMT with a full rotor, one barrel, 27 jewels, and a 50-hour power reserve. The free-sprung balance beats at 28,800 vibrations per hour, while a Swiss lever escapement and six-position adjustment support a stated rate of plus five to minus three seconds per day. Hacking seconds allows precise setting.
