Product description
About this Grand Seiko watch
The Grand Seiko STGK023G expresses Grand Seiko’s approach to precision and Japanese design through a mother-of-pearl dial framed by diamonds in a compact mechanical design. A 27.8 mm stainless steel case with dual-curved sapphire crystal balances visual refinement with everyday wearability.
Inside, the Calibre 9S27 Self-winding with manual-winding delivers a power reserve of approximately 50 hours, complemented by 10 bar water resistance. Its compact proportions make it a refined choice for collectors who value detail, comfort and Japanese craftsmanship.
