Grand Seiko Evolution 9 Mount Iwate Ice Blue SLGH027: A Mountain-Inspired Marvel
Following the impressive launch of the Evolution 9 collection from Grand Seiko in 2020, which included a mix of mechanical and Spring Drive movements, the brand has continued to innovate. Among their designs, the White Birch SLGH005 became a standout, inspiring a suite of new models. Now, Grand Seiko is elevating this line with the Evolution 9 reference SLGH027, a limited edition piece that pays homage to Mount Iwate.
The Evolution of Grand Seiko’s Inspiration
Grand Seiko’s production line is divided into two distinct studios: the Shinshu Watch Studio for Spring Drive watches and the Shizukuishi Studio for mechanical watches. The Shizukuishi Studio is situated next to Mount Iwate, an influence evident in many of the brand’s dial designs. However, the Evolution 9 collection has previously seen limited Mount Iwate-inspired dials, predominantly in the SLGH019 Midnight Blue and Tentagraph SLGC001.
Introducing the Grand Seiko Evolution 9 Mount Iwate Ice Blue SLGH027
The SLGH027 takes the traditional Mount Iwate texture and transforms it into a more dynamic, intricate pattern that captures the essence of the mountain from above. This new dial features a rich, ice-blue color combined with a blued steel seconds hand, adds an elegant touch to its already striking design. Grand Seiko has retained the oversized, faceted markers and hands, which are signature features of the Evolution 9 series.
Modern Design and Superior Craftsmanship
The SLGH027 retains the same sleek, modernised case design as the White Birch and Atera Valley models. With a diameter of 40mm, a thickness of 11.7mm, and a length of 47mm, the watch offers a comfortable fit.
Constructed from Ever-Brilliant Steel, which is 1.7 times more pitting-resistant than traditional stainless steel, the case is durable and maintains its shine over time. The case has a brushed finish with Zaratsu polished accents, adding a touch of elegance. It is equipped with a box-shaped sapphire crystal, a screwed see-through caseback, and a screw-in crown, ensuring a water resistance of 100 meters.
Powerful Calibre 9SA5 Movement
Inside the SLGH027 is the Calibre 9SA5, a sophisticated automatic movement known for its accuracy and durability. This high-frequency movement beats at 5Hz and features Grand Seiko’s Dual Impulse Escapement and a free-sprung balance, ensuring precise timekeeping. Power reserve is ample at 80 hours thanks to the sequential arrangement of two barrels.
The watch comes on an Ever-Brilliant Steel bracelet, featuring a folding clasp with the GS logo in 18k rose gold, adding a premium finish to the already impressive design.
Availability and Pricing
The Grand Seiko Evolution 9 Mount Iwate SLGH027 will be available from GS boutiques and selected retailers starting May 2025. This limited edition of 1,200 pieces is priced at EUR 11,500, making it an attractive offering for discerning watch enthusiasts.
Conclusion
The Grand Seiko Evolution 9 Mount Iwate SLGH027 is a testament to the brand’s commitment to innovation and heritage. By reimagining the familiar White Birch design and introducing a unique, richly textured dial inspired by Mount Iwate, Grand Seiko continues to captivate its audience. Whether you’re a seasoned collector or a new admirer, the SLGH027 is sure to be a valuable addition to any watch collection.
