The rich blue dial of the SBGH273 Autumn Equinox exemplifies the deep and melancholic expressions of the Tsukiyo moonlit night. The Hi-Beat 36000 Caliber 9S85 is the result of many years of development and advances. With its higher oscillation rate of ten beats per second, greater accuracy is achieved. The Summer and Autumn timepieces features the power and dynamism of the Mechanical Hi-Beat 36000.
