Grand Seiko Evolution 9 Collection Spring Drive U.F.A. Ushio 300 Diver SLGB025

The SLGB025 channels the serenity of shallow coastal waters with a deep green Ushio-patterned dial. Subtle texture, gradient shading, and prominent diamond-cut hour markers maximize readability, while the broad, luminescent hands ensure clarity in any light. Its ceramic 120-click unidirectional bezel mirrors the dial’s color, emphasizing the natural inspiration of tides and waves.

Inside, the Spring Drive Caliber 9RB1 delivers Grand Seiko’s Ultra Fine Accuracy with ±20 seconds per year, supported by a vacuum-sealed oscillator and thermo-compensated IC. The movement’s power reserve, three-day autonomy, and offset magic lever for rapid winding make it a robust and reliable tool for professional or recreational diving.

Housed in High-Intensity Titanium, the 40.8mm case offers durability and lightness, while the Evolution 9 ergonomic design and newly developed extension clasp with micro-adjustment ensure a secure and comfortable fit on the wrist. The SLGB025 embodies precision, elegance, and the enduring beauty of Japan’s coastal waters.
