Seiko Rainbow - White Dial with Rainbow Arc

The matte white dial is crisp and highly legible, with black printed hour markers and a fine 24-hour inner scale. The rainbow arc, rendered in vivid red, orange, yellow, green, and blue, adds a unique character rarely seen in mainstream Seiko models. The contrast between the colorful motif and monochrome indices gives this watch both a playful and sophisticated appeal.

The baton-style hour and minute hands feature black framing with luminous inlays, ensuring clarity in various lighting conditions. The slim, black second hand complements the dial’s minimalistic symmetry without distracting from the central rainbow motif.

The 36.5 mm stainless steel case is designed with a brushed finish on the top surface and polished chamfered edges, providing a balanced mix of sportiness and refinement. The slim polished bezel frames the dial elegantly, emphasizing the watch’s vintage proportions.

Rainbow 7009-316A - Crown

The original Seiko signed crown is positioned discreetly at 4 o’clock, flush with the case for comfort and aesthetic harmony. This recessed design reduces the risk of accidental adjustments and reflects Seiko’s attention to ergonomic detail.

Seiko Rainbow Stainless Steel Bracelet

The integrated stainless steel bracelet features three-piece links with a brushed outer surface and polished central section. This construction offers both durability and a period-correct style, ensuring the watch sits securely and comfortably on the wrist.
