Born from Grand Seiko’s pursuit of precision, the SLGB003 reflects winter in its most elemental form.
Its ice-inspired dial evokes the frost-covered forests of Shinshu, where pale light filters through still air. Housed in a 37mm High-Intensity Titanium case, it combines lightness with strength, finished with sharp Zaratsu polishing.
At its core is the Spring Drive U.F.A. Calibre 9RB2, delivering exceptional annual accuracy of ±20 seconds and a 72-hour power reserve, one of Grand Seiko’s most precise expressions of timekeeping.
