Grand Seiko, 37.3mm, Calibre 9S64 Manual-Winding, SBGW031
The Grand Seiko SBGW031 is a beautifully restrained mechanical dress watch that captures the traditional Grand Seiko approach to precision, finishing and legibility. Its compact 37.3mm stainless steel case is paired with a subtly warm silver-toned dial, sharply finished hands and applied hour markers, creating an elegant design with distinctly classical proportions.
Introduced in 2012, the SBGW031 belongs to an important generation of Grand Seiko's modern hand-wound watches. Its curved dial and box-shaped sapphire crystal give the watch a vintage-inspired profile, while the see-through caseback provides a view of the mechanical movement. The model has since been discontinued, making the SBGW031 an appealing earlier expression of Grand Seiko's contemporary hand-wound lineage.
At its heart is the Grand Seiko Calibre 9S64, a manually wound mechanical movement developed to significantly extend the running time of Grand Seiko's previous hand-wound generation. Fully wound, the 9S64 delivers an impressive approximately 72-hour power reserve, allowing the watch to run for around three days. Specifications
