The Beauty of the White Birch Forest After Dark
The Grand Seiko Evolution 9 Collection SLGH017G, affectionately known by enthusiasts as the "Night Birch", captures the quiet atmosphere of the white birch forests surrounding the Grand Seiko Studio Shizukuishi after sunset. Building on the success of the celebrated White Birch SLGH005, this striking interpretation presents the same deeply textured dial in rich black tones, recreating the interplay of moonlight and shadow beneath the forest canopy.
Powered by Grand Seiko's revolutionary Hi-Beat Calibre 9SA5 and housed within a lightweight High-Intensity Titanium case, the SLGH017G represents the perfect union of cutting-edge mechanical innovation and Japanese artistry.
Evolution 9 Design at Its Finest
The SLGH017G belongs to Grand Seiko's acclaimed Evolution 9 Collection, a design philosophy that refines the iconic 44GS principles for modern wearability. Every surface has been carefully engineered to improve aesthetics, comfort and legibility.
The black birch-pattern dial is created through an intricate multi-stage pressing process, producing remarkable depth and texture that shifts dramatically as the light changes. Powerful faceted hands and deeply grooved indexes ensure exceptional readability, while Grand Seiko's renowned Zaratsu polishing creates distortion-free mirror finishes that contrast beautifully against delicate hairline brushing.
Revolutionary Hi-Beat Calibre 9SA5
At the heart of the SLGH017G beats the Grand Seiko Calibre 9SA5, one of the most advanced mechanical movements ever developed by the brand.
The movement incorporates several groundbreaking innovations, including:
- Approx. 80-hour power reserve
- Hi-Beat frequency of 36,000 vibrations per hour (10 beats per second)
- Grand Seiko Dual Impulse Escapement
- Twin-barrel architecture
- Free-sprung balance
- Automatic and manual winding
- Grand Seiko adjusted accuracy of +5 to -3 seconds per day
- Typical wearing accuracy of +8 to -1 seconds per day
These technical advances improve efficiency, stability and precision while allowing the movement to achieve one of the longest power reserves available in a Hi-Beat mechanical watch.
Crafted in High-Intensity Titanium
The 40mm case and bracelet are crafted from High-Intensity Titanium, a material significantly lighter than stainless steel while offering exceptional strength and corrosion resistance.
The Evolution 9 case has been designed with a lower centre of gravity, allowing the watch to sit securely and comfortably on the wrist throughout the day. A box-shaped sapphire crystal with anti-reflective coating enhances the vintage-inspired profile while ensuring excellent dial clarity.
With 100 metres of water resistance, a screw-down crown and an exhibition sapphire case back, the SLGH017G is designed to be enjoyed every day while showcasing the remarkable Calibre 9SA5 within.
A Contemporary Grand Seiko Icon
The Night Birch has quickly become one of Grand Seiko's most admired modern references. Its dramatic dial, lightweight titanium construction and revolutionary movement combine to create a watch that is technically impressive yet visually understated.
For collectors seeking a distinctive Grand Seiko that perfectly embodies the brand's philosophy of "The Nature of Time", the SLGH017G is an exceptional choice.
