Grand Seiko STGF387

Ref. STGF387G
Dress

Grand Seiko is praised for its stunning Shunbun dial, with color and texture that shift from powder blue to light purple depending on the light, and its 44GS-style case. Some owners wish for a larger, diamond-free option for a unisex watch, and others lament the lack of a Spring Drive movement in a smaller case. One owner finds the Spring Drive version too thick and wishes it were 9F quartz powered. Owners widely report Grand Seiko offers finishing and quality on par with or exceeding Swiss luxury brands, though some find their bracelets inferior. Overall, owners rate Grand Seiko highly for its unique and beautiful dial finishing.
