Grand Seiko 2024 Evolution 9 Collection Spring Drive 5 Days Titanium "Atera Valley" River Blue Dial 

SLGA025

From the Waters of Atera to the World of Collectors

The Grand Seiko SLGA025 captures the spirit of flowing water with a dial inspired by the Atera River. Its textured surface shifts from turquoise to deep forest green, revealing new facets with every glance — a living reminder of Grand Seiko’s devotion to nature and artistry.

Crafted from high-intensity titanium, the SLGA025 is 30% lighter than steel yet remarkably durable against scratches and corrosion. The 40mm case and 11.8mm profile balance modern presence with refined elegance, while the titanium bracelet and three-fold clasp ensure comfort and security.

Powered by the Spring Drive Caliber 9RA2, the SLGA025 delivers ±10 seconds per month accuracy and a 120-hour power reserve. Every detail — from Zaratsu-polished surfaces to the seamless case and bracelet integration — reflects Grand Seiko’s relentless pursuit of perfection.

For collectors, this is more than a watch. It is a statement of heritage, innovation, and artistry — a piece to be experienced, not just worn.
