Overview

About this reference

The Grand Seiko SBGA481 is a substantial Sport watch shaped around a 44.5 mm titanium case and bracelet. Its white lion-mane dial gives the broad design a textural focal point, while the date and power-reserve display make the face functionally rich without adding a chronograph. Sapphire crystal, LumiBrite, and 200-metre water resistance reinforce the watch's outdoor intent, and the see-through back reveals its unusual drive system.

Calibre 9R65 is Spring Drive, combining a mainspring-powered train with electronic regulation for a stated accuracy of plus or minus one second per day. Its 30 jewels and single barrel support 72 hours of reserve, with central seconds, date, and a visible power-reserve indication. The 32,768 Hz reference oscillator gives the movement its measured precision, while the smooth seconds display supplies the defining visual expression.
