Grand Seiko Hi-Beat 36000 Sport Collection GMT – 44.2 mm

Reference Number
SBGJ277G

Imagine a valley where the highest peaks are capped with snow, even in summer. Such a snowy valley enchants the hearts of those who happen to glimpse its rare scenery. In the SBGJ277, the green of the rotating bezel contrasts with the pure white of the finely molded dial pattern, evoking this special mountain scene. One characteristic of this model is its prominent rotating bezel, which imparts a sporty character and allows wearers the ability to check the time in up to three different time zones. The watch houses the mechanical Hi-Beat 36000 GMT Caliber 9S86, which runs at ten beats per second while offering excellent rate stability and resistance to outside interference.
