Grand Seiko Evolution 9 White Birch

About this reference

The Grand Seiko Evolution 9 SLGA009 entered production in early 2022 and remains a current catalog offering. Collectors distinguish this reference from the earlier SLGH005 by its Spring Drive Caliber 9RA2, which provides a five-day power reserve and a movement accuracy of +/- 0.5 seconds per day. The 40mm stainless steel case follows the Evolution 9 design language, featuring a lower center of gravity and wider lugs for stability. The dial utilizes a pressed pattern inspired by white birch forests in Shizukuishi, characterized by shallower, more subtle textures than its high-beat predecessor. On the secondary market, the SLGA009 typically trades between $6,500 and $8,000 depending on condition and completeness. A notable technical distinction of this reference is the relocation of the power reserve indicator to the caseback side, resulting in a more symmetrical dial layout compared to previous Spring Drive models.
