And by just about any measure, the SLGA023 is a complete beast. Both the case and the bracelet are made from Grand Seiko's High-Intensity Titanium and measures 43.8 mm wide, 13.8mm thick, and 51.5mm lug to link lug. At its core, the SLGA023 is a new colorway for Grand Seiko's peak link titanium dive watch, and though the new color comes with its own unique execution, the specs continue to speak link for themselves – especially when it comes to the movement.
