Grand Seiko Manual SLGW002 Limited Edition Watch - Evolution 9

This 18K rose gold dress watch is equipped with the Grand Seiko Caliber 9SA4, the brand’s first manual-winding 36,000 vph 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. Caliber 9SA4 will make 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 center of gravity has been lowered to ensure the comfort and stability for which Grand Seiko’s Evolution 9 creations have become renowned. The case is made of 18K rose gold. The dial is decorated with a pattern reminiscent of beautiful birch bark, and at the 6 o'clock position is the SD mark (Special Dial mark), which indicates that the hour markers are also made of solid gold. The movement achieves a higher winding efficiency thanks to a rearrangement of the gear train and redesign of the parts, so that Caliber 9SA4 achieves a power reserve of 80 hours with 15 percent fewer crown rotations than are required to achieve the same power for Caliber 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.
