Brand: Grand Seiko | Model: Spring Drive U.F.A. Ushio 300 Diver SLGB023 | Reference: SLGB023 | Category: Dive Watch / Spring Drive | Release Year: 2026
The Grand Seiko SLGB023 is a 2026 Evolution 9 Spring Drive U.F.A. Ushio 300 Diver with a compact 40.8mm High-Intensity Titanium case, blue 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 blue Ushio dial, 300m water resistance, titanium case and bracelet, and ±20 seconds per year accuracy make it one of Grand Seiko’s most practical technical releases of 2026.
The SLGB023 should appeal to collectors who want a serious Grand Seiko diver with cutting-edge Spring Drive accuracy. Its 40.8mm case is unusually compact for a professional Grand Seiko dive watch, while the High-Intensity Titanium construction, blue Ushio dial, 300m water resistance, and Caliber 9RB1 U.F.A. movement give it strong everyday and collector appeal.
