Seiko Rainbow, Ref. 7009-316A, Cal. 7009, Men’s Automatic Watch

A five-colour rainbow arc above 6 gives this Seiko Rainbow watch from 1982, reference 7009-316A, its distinctive dial identity. Black printed markers and a fine inner 24-hour scale surround the matte white surface, with luminous black-framed hands. Automatic caliber 7009 powers the 36.5 mm steel case, joined to its original three-piece-link integrated bracelet.

Matte white with a red-to-blue rainbow arc

The clean matte white dial has black printed hour markers and a fine inner 24-hour scale. Above 6, the arc combines vivid red, orange, yellow, green and blue. The colours contrast with the monochrome markings, making the motif a distinct part of the display.

Baton-style hour and minute hands have black framing and luminous inlays. A slim black central seconds hand follows the same dark treatment without distracting from the coloured arc. The watch has a day-date complication alongside its time display.

Brushed steel, polished chamfers and flush signed crown

The stainless steel case measures 36.5 mm in diameter and 42 mm from lug to lug. A brushed top contrasts with polished chamfered edges and a slim polished bezel. The narrow rim leaves the dial prominent within the modest case size.

The original Seiko-signed crown sits at 4, recessed flush with the case. Its position keeps the head unobtrusive and reduces accidental adjustment.

The original integrated stainless steel bracelet has three-piece links, with brushed outer surfaces and polished central sections. The attachment continues the case’s surface contrast, preserving the cohesive head-and-bracelet form.
