SBGJ263 features Grand Seiko's modern 44GS design, a contemporary take on a watch that was first released in 1967 and formed the cornerstone of the Grand Seiko Style.

The case and bracelet are made of Ever-Brilliant Steel, a stainless-steel alloy that features even greater corrosion resistance than what is typically used across the watch industry today. It has a PREN (Pitting Resistance Equivalent Number) value 1.7 times higher than that of the grade of steel used in most high-class watches. Visually, it also has a brilliant white hue that enhances the beauty and Zaratsu finishing of the watch.
