SPRING DRIVE ‘OMIWATARI’ MYSTERIOUS MIDWINTER BLUE
The light blue textured dial of this timepiece is inspired by a mysterious natural midwinter phenomenon called ‘Omiwatari’ occurring on the frozen surface of Japan’s Lake Suwa near Shiojiri, birthplace of Grand Seiko’s Spring Drive movement.
‘Omiwatari’ are ice ridges created when the temperature changes stretch and contract the frozen lake surface. Considered to be ‘God’s Footsteps,’ religious ceremonies are held to predict the forthcoming year’s harvests and good fortune by looking at the direction and height of the ridges.
THE TIMELESS BEAUTY OF LIGHT AND SHADOW
There is no shadow without light and no light without shadow. The ‘Grand Seiko Style’ is based on the Japanese sense of aesthetic, expressed in a unique design language through highly polished
smooth surfaces where the play of light and shadow creates beautiful harmony.
The distortion-free, brilliant mirrored finish of this timepiece is achieved through our signature Zaratsu polishing – an in-house technique that requires years of training to master.
THE FLOW OF TIME IN PERFECT GLIDE MOTION
The SBGY007 is powered by a manual-winding Spring Drive Calibre 9R31 that delivers an accuracy rate of ±1 seconds per day. The movement uses two mainsprings set in parallel within a single barrel
to deliver a power reserve of 72 hours.
Spring Drive generates energy like a traditional mechanical watch but combines this with an electronic regulator to deliver a level of precision that no mechanical watch can match. The signature of Spring Drive is the smooth motion of its second hand. The hand moves in a silent and beautiful glide motion, rather than the one-second tick of a quartz watch or the rapid beat of a mechanical watch.
