Conventionally, beauty is in the eye of the beholder but not for Grand Seiko. The Grand Seiko conception of beauty is a central element of a clearly defined set of principles that were first demonstrated in the 44GS released in 1967. This modern re-interpretation of the 44GS has a case that is faithful to its heritage. Here is where history, hand craftsmanship and cutting-edge technology converge. The midnight blue dial of SBGP005 provides the perfect background for the diamond-cut hands and indexes. The Zaratsu polished surfaces shine with a quiet brilliance. Light and shadow combine in an ever-changing tableau. Together, these elements combine to create the unmistakable beauty of Grand Seiko.
Calibre 9F85 with a time-difference adjustment function
Caliber 9F85 has a time difference adjustment function that allows the hour hand to be adjusted without stopping the seconds hand and thus preserving its high precision when the wearer changes time zones.
The exterior design is a modern interpretation of the brilliant and shining timepiece defined as part of the idea of the Grand Seiko Style, the design concept that was established with the launch of 44GS in 1967.
The case utilizes perfect mirror-finished surfaces created using Zaratsu polishing, and combines beautiful and shining mirror-finished and hairline-finished surfaces for three-dimensionality. The expansive dial has twelve multi-faceted hour markers. The complementary arrangement of these elements gives the watch a beautiful radiance and visibility.
