Seiko SQ — The elegance of a sunburst blue dial This vintage Seiko SQ watch, produced around 1979, is immediately captivating thanks to its master asset: a sunburst blue dial of rare depth. Darker along the edges and luminous at the center, this midnight blue captures the light and shifts in tone with the movement of the wrist — a discreet, refined elegance, housed in a round dress watch with clean lines.

With its measured diameter of 32.5mm, it wears with natural ease, as fitting on a man's wrist as on a woman's, for those who appreciate dress watches in a restrained format.

The SEIKO QUARTZ signature and the SQ logo complete a minimalist composition in which blue is the true star. The silver baton hands, perfectly matched to the markers, glide across this dial with understated sophistication. Protected by a Crystal crystal in very good condition and powered by a reliable Seiko quartz movement, this piece is fitted with a black leather strap that enhances the depth of the blue dial.
