Grand Seiko SLGH009 Unboxing

For over sixty years, advances in the fundamentals of watchmaking, precision, durability and beauty, have been of paramount importance to Grand Seiko. With the Spring Drive Caliber 9RA5 and the Hi-Beat 36000 Caliber 9SA5 launched in 2020, Grand Seiko took an important step forward in precision and overall performance. In 2021, a new Spring Drive movement, Caliber 9RA2, was made. It has the same high functionality as Caliber 9RA5 but, thanks to the repositioning of the power reserve indicator to the back of the movement and the reduction of the height of the hands above the dial, it allows a slimmer　case profile.

Today, Grand Seiko introduces two watches featuring Calibers 9SA5 and 9RA2 that are made of Ever-Brilliant Steel*, a type of stainless steel that is more corrosion resistant and therefore more durable than that which is commonly used in watches today. It has a brilliant white hue that enhances the beauty of the watch and is perfectly suited to the Grand Seiko Style, which was established in 1967 and whose 55th anniversary these two creations celebrate.

Both timepieces share the same dial design which 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. The sharp edges of the hour and minute hands provide a pleasing contrast with the gentle curves of the dial pattern. The gold-tone seconds hand extends right across the dial and its motion captures the serene passage of celestial time. The dial of the Hi-Beat version is blue, while the Spring Drive version is in dark gray.


The see-through sapphire crystal backs reveal the beautifully finished bridges and are clear evidence of the skilled craftsmanship of the men and women of the two studios where the watches are made and hand assembled.
