A refined expression of Seiko’s early 1980s design language, this Seiko Octo Bezel Tonneau (Ref. 6430-5230RD) stands out with its sculpted geometry and minimalist execution. The 29x37mm case features a distinctive octagonal bezel with soft edges that merge seamlessly into the curved tonneau profile — a design that captures the elegance of Seiko’s transitional era between the 1970s’ bold forms and the sleek simplicity of the ’80s.

The two-tone case combines polished steel with a gold bezel, framing a textured champagne dial with matching gold hands and indices. Powered by a Quartz movement, it offers dependable accuracy with the timeless aesthetics of vintage Seiko dress watches.

Still accompanied by its original strap and presentation box, this piece remains a pristine example of Seiko’s commitment to craftsmanship and design detail during the height of its quartz innovation period.
