A dial inspired by the stars
The dial has a depth and a texture that attract the eye and take the imagination upwards towards the sky at night. The deeply etched pattern is that of the elliptical orbit of the stars as they move across the heavens and it captures the serene passage of celestial time with its flowing, unbroken lines.
With its highly efficient Dual Impulse Escapement, Grand Seiko free-sprung balance and twin barrel construction, Caliber 9SA5 delivers a precision rate of +5 to -3 seconds per day and a power reserve of 80 hours. The caliber represents the very finest in modern watchmaking, combining unique and advanced technologies with craftsmanship of the highest order.
When seen through the sapphire case back, different textures are seen to be in harmony. The side of the movement has a matte finish and a subdued tone that absorbs the light whereas the ridges, edges and screw holes are sharply cut and polished to a brilliant finish that sparkles with precision. The tempered blue screws and gold tone add bold accents of color.
Ever-Brilliant Steel: the world’s most corrosion resistant steel.
Known as Ever-Brilliant Steel, thanks to its brilliant white hue, this steel is more corrosion resistant than that which is used in even the most prestigious watches today.*
* This stainless steel has a PREN (Pitting Resistance Equivalent Number) value 1.7 times higher than that of the grade of steel used in most high-end watches. PREN is a widely accepted standard used to measure corrosion resistance.
