Seiko 5 7009-4040 Men's Automatic Watch, 1983

An inner 24-hour scale gives the black dial of this 1983 Seiko 5 a more technical layout. Reference 7009-4040 retains the familiar framed day-date display, luminous batons and automatic caliber 7009. Its angular 37 mm steel case flows into the original bracelet, with a slim profile and a recorded 19 cm wrist fit.

Black dial with an inner 24-hour scale

The dial has a smooth, non-sunburst black surface. A printed inner ring of 24-hour numerals adds another scale within the rectangular markers, while the outer minute track carries small luminous plots. The applied hour markers also have luminous inserts, keeping the darker face clearly divided.

A Seiko 5 emblem identifies the line, and a framed day-date window occupies 3 o’clock. Baton-shaped hour and minute hands carry luminous centers; a slim central seconds hand adds a red accent near its tip. That small red detail supplies a separate color against the black-and-silver display.

The 24-hour numerals are a printed dial scale. The documented functions remain hours, minutes, central seconds, day and date.

Angular case flowing into the bracelet

The stainless steel case of this vintage Seiko watch has an integrated visual flow at the lugs. Its straight lines continue into the original steel bracelet, while brushed and polished transitions distinguish the upper planes and edges. The side profile is slim and balanced.

The case measures 37 mm across and 40 mm from lug to lug. The short difference between these dimensions makes the overall length useful when judging fit beside the central width. The lug fitting is 19 mm, and the bracelet’s recorded wrist fit is 19 cm.

A compact crown sits around 4 o’clock, partly recessed into the lower-right flank. Its gripping edge remains accessible while limiting the interruption of the case outline.

Automatic 7009 and original components

Seiko caliber 7009 is an automatic mechanical movement providing the time and day-date display.

This used example has a clean dial layout and well-defined case lines, retaining the strong overall presentation described for it. The watch components and bracelet are original. It is fully serviced and fully operational, comes with a 12-month warranty, and is available with worldwide shipping.
