Quick TakeThe dial's subtle texture dances with light, while the precision of the Spring Drive movement hums quietly beneath. The SLGA025 feels feather-light and reassuring on the wrist thanks to its high-intensity titanium case, yet every detail, from the zaratsu polishing to the meticulously applied indices, screams luxury and purpose. The power reserve indicator is a reminder of the remarkable 120-hour autonomy of the Caliber 9RA2, while the date window is a subtle nod to practicality. Grand Seiko's renowned craftsmanship shines through, transforming a practical timepiece into an art piece.

DescriptionThe Grand Seiko SLGA025 features a high-intensity titanium case with a diameter of 40.0mm, a lug-to-lug measurement of 47.9mm, and a thickness of 11.8mm. The case back is transparent and secured with screws, offering a view of the intricate Spring Drive movement within. The dual-curved sapphire crystal has an anti-reflective coating on its inner surface, ensuring optimal legibility. With a band width of 22mm, the bracelet culminates in a secure three-fold clasp with a push-button release, designed to fit a wrist circumference of up to 195mm. The watch boasts a weight of 112 grams, providing a substantial yet comfortable presence. This timepiece is equipped with a screw-down crown, enhancing its water resistance to 10 bar (approximately 100 meters), and features an allergy-safe metal composition, making it suitable for sensitive skin. Additionally, the watch is resistant to magnetic fields up to 4,800 A/m, ensuring reliable performance in various environments.

Powering the SLGA025 is the Spring Drive Caliber 9RA2, a self-winding movement renowned for its exceptional accuracy and power reserve. This movement delivers an impressive power reserve of approximately 120 hours (5 days) when fully wound. Furthermore, the Caliber 9RA2 maintains an accuracy of ±10 seconds per month, which translates to ±0.5 seconds per day, a remarkable feat for a mechanical watch. The dial features a power reserve indicator, allowing the wearer to monitor the remaining energy. Inspired by the natural beauty of the Atera Valley in Nagano Prefecture, the dial's emerald-green hue evokes the clear, flowing waters of the Atera River, set against the backdrop of lush, mountainous terrain. This design not only pays homage to the region's natural environment but also enhances the watch's aesthetic appeal, creating a harmonious blend of engineering precision and artistic expression.
