Grand Seiko · Spring Drive
Overview
The Grand Seiko Heritage SBGA413 is the 'Shunbun' (spring) model from the brand's USA-exclusive Four Seasons collection, introduced in February 2022. It pairs a 40mm High-Intensity Titanium case with a textured soft-pink dial evoking cherry blossoms (sakura) in bloom, framed by a box-shaped sapphire crystal. Power comes from the in-house Spring Drive Caliber 9R65, which blends mechanical winding with an electromagnetic glide-wheel regulator for a smoothly sweeping seconds hand, ±1 second/day accuracy, a power-reserve indicator, and roughly 72 hours of reserve. It is a non-limited production model.
