A manually wound Evolution 9 dress watch with high-beat precision and 80 hours of power reserve.

This dress watch is equipped with the Grand Seiko Calibre 9SA4, the brand’s first manual-winding 36,000vph mechanical movement to be created in approximately 50 years.

Today, the ritual of winding a watch is one of life’s pleasures. The simple act of turning the crown taps into the senses to forge a deeper connection with time’s natural flow. In the 1960s and ’70s, manually wound 10-beat Grand Seiko creations were manufactured in the pursuit of better rate stability and higher precision.

Calibre 9SA4 makes its debut in a new dress watch belonging to the Evolution 9 Collection, whose design represents a continuation of the Grand Seiko Style that reaches back to the iconic 44GS of 1967. Only this time, the Evolution 9 Style itself has been further refined to create a watch that instantly communicates the charm, elegance, grace, and subtlety one would expect of a hand-wound dress watch. Several aspects of the design have been revisited – from the prominent, grooved indexes, which have been slimmed down and elongated, to the multifaceted lugs, which are now narrower and have a smaller surface area. The watch’s centre of gravity has been lowered to ensure the comfort and stability for which Grand Seiko’s Evolution 9 creations have become renowned.

The case and clasp are made of Grand Seiko’s Brilliant Hard Titanium. The alloy is brighter than traditional titanium, causing the case’s Zaratsu-polished surfaces to appear even more radiant and achieving a sparkle of quality and beauty befitting a Grand Seiko dress watch. Brilliant Hard Titanium makes the watch not only light but also highly resistant to corrosion and scratches while commanding a hardness double that of standard stainless steel.

The movement achieves a higher winding efficiency thanks to a rearrangement of the gear train and redesign of the parts, so that Calibre 9SA4 achieves a power reserve of 80 hours with 15 percent fewer crown rotations than are required to achieve the same power for Calibre 9SA5 when winding it by hand. Thanks to its svelte movement, the latest birch-inspired mechanical watch is 38.6mm in diameter and achieves a slimness of 9.95mm.

A dial reflecting the beauty of the white birch

 The new creation’s dial is inspired by the slender white birch trees that thrive in northern parts of Japan and that grow in profusion near the Grand Seiko Studio Shizukuishi. The exquisite pattern echoes the beauty of the birch tree’s bark with its intricate, multi-dimensional texture. Combined with the watch’s elegant design and the movement’s high precision, the new creation offers a refined experience of the nature of time.

A beautiful view through an exhibition caseback

The click is in the shape of a wagtail, a bird recognized as special to Morioka, a city close to the Grand Seiko Studio Shizukuishi, where this and all Grand Seiko mechanical watches are crafted. Thanks to the redesign of the movement, the bird-like pecking motion of the click is visible to enjoy through the sapphire crystal case back during the hand-winding process. Together with the delicate finishing of the movement inspired by the Shizukuishi River, Calibre 9SA4 not only showcases the very best of Grand Seiko’s mechanical watchmaking capabilities but also captures the beauty of the studio’s natural surroundings.

Calibre 9SA4

Calibre 9SA4 was created to provide the ultimate hand-winding experience, with a winding sound and feel demonstrating its craftsmanship and quality. It has a high frequency of 10 vibrations per second, which leads to stable precision, and a long power reserve of up to 80 hours.
