Cazalea's post introduces the Grand Seiko Evolution 9 Style, focusing on the 'White Birch' models and their respective movements. He meticulously compares the Hi-Beat 9SA5 and Spring Drive 9RA2 versions, offering a detailed look at Grand Seiko's design philosophy and technical advancements. This article is essential for understanding the brand's commitment to precision and aesthetic refinement.
In 2021, Grand Seiko introduced a high-beat watch inspired by the slender and beautiful white birch trees of the Hiraniwa Plateau in northern Japan. This timepiece was warmly praised by watch fans worldwide for its intricately textured dial and for the revolutionary Hi-Beat 36000 Automatic Caliber 9SA5 that powered it. Its wide acclaim culminated in its selection as the winner of the Men’s Watch prize at the 2021 Grand Prix d’Horlogerie de Genève. Shown below, on the left.
Now, a new creation powered by the latest and finest Spring Drive Caliber 9RA2 captures the atmosphere of a white birch forest but in a subtly new way that echoes the feeling of the forests of Shinshu, home to the studio where all Grand Seiko Spring Drive watches are made. The watch will be available at the Grand Seiko Boutiques and selected retail stores worldwide in February 2022. Shown above on the right, and below:
The craftsmanship is evident in every detail. The delicately textured dial and the tempered blue seconds hand reveal an artistry that is matched by the ‘frost’ finishing of the movement, whose beauty is clearly visible through the sapphire case back. To watch the completely smooth glide motion of the seconds hand as it moves serenely across the subtly patterned dial is to be brought closer than ever to the tranquil, seamless and natural flow of time.
The delicate texture of the movement's finish reflects the frost that winter brings to the trees in Shinshu. The bridge lines and hole edges are diamond-cut to reflect light from all angles and the jewels and the tempered blue power reserve indicator add a quiet sparkle that is a delight to behold. Caliber 9RA2 delivers a power reserve of up to 120 hours and is accurate to ±10 seconds per month.
The watch’s design is true to the Grand Seiko Style defined back in 1967 with the celebrated 44GS. However, it also announces an important step forward in Grand Seiko design. To be known as the Grand Seiko Evolution 9 Style, this new grammar of design takes Grand Seiko’s ideals of beauty, legibility and wearing comfort to new levels. Its Zaratsu polished, distortion-free mirror finish and delicate hairline finish alternate to give the case a quiet and harmonious glow. Its powerful hands and grooved, prominent markers ensure perfect legibility. The case’s center of gravity is lower, and the bracelet has just the right width and depth to ensure that the watch sits easily and securely on the wrist.
The ‘White Birch’ timepieces, both high-beat and Spring Drive, form the new Evolution 9 Collection starting in February 2022.
