Grand Seiko Heritage Collection Hi-Beat GMT 44GS
SBGJ255G
Created for the 55th anniversary of the 44GS, Grand Seiko Heritage Collection SBGJ255G distils the design language that has shaped the brand since 1967. Its high-intensity titanium case and bracelet are around 30% lighter than stainless steel, while sharp facets and distortion-free Zaratsu-polished surfaces play with light and shadow in unmistakable Grand Seiko fashion.
The crisp white dial is animated by blue accents and a tempered-blue GMT hand, allowing a second time zone to be read at a glance. Beneath it, Hi-Beat Caliber 9S86 runs at 36,000 vibrations per hour, offering approximately 55 hours of power reserve and an independently adjustable local-hour hand; this commemorative edition is limited to 1,200 pieces worldwide.
