Brand: Grand Seiko | Model: Spring Drive U.F.A. Ushio 300 Diver SLGB025 | Reference: SLGB025 | Category: Dive Watch / Spring Drive | Release Year: 2026
The Grand Seiko SLGB025 is a 2026 Evolution 9 Spring Drive U.F.A. Ushio 300 Diver with a compact 40.8mm High-Intensity Titanium case, green Ushio dial, and Caliber 9RB1.
Collectors may appreciate this release because it brings Grand Seiko’s U.F.A. Spring Drive accuracy into a smaller professional dive-watch format. The green Ushio dial is inspired by shallow coastal waters, while the titanium case, 300m water resistance, and ±20 seconds per year accuracy make it highly practical.
The SLGB025 should appeal to collectors who want a serious Grand Seiko diver with advanced Spring Drive accuracy and a distinctive green dial. Its compact 40.8mm High-Intensity Titanium case, 300m diver’s rating, Caliber 9RB1 U.F.A. movement, and improved clasp system make it one of Grand Seiko’s strongest technical dive releases for 2026.
