Seiko 5, Ref. 7009-3040, Cal. 7009, Men’s Automatic, 1990

Seiko 5 7009-3040 — dark blue depth in classic proportions

The 37 mm stainless steel case and 42 mm lug-to-lug measurement give this Seiko 5 a balanced wrist presence that remains comfortably vintage in scale. Its polished bezel, softly shaped case and tapered lugs frame a dark blue dial whose color shifts subtly with the light. The 19 mm strap width keeps the watch visually grounded, while the combination of steel, blue and warm gold-tone accents gives the piece a restrained but distinctive appearance.

Blue dial with mixed gold-tone hour furniture

The dial uses a deep blue surface with a fine outer minute track and a thin circular line inside the hour markers. Applied gold-tone markers alternate between elongated rectangular forms and small round dots, creating a more decorative layout than a typical utilitarian Seiko 5. The SEIKO signature and 5 emblem sit beneath 12 o’clock, while AUTOMATIC is printed discreetly in the lower half. Light age-related character is visible on some of the applied furniture.

Framed day-date and luminous-style handset

A framed day-date aperture occupies 3 o’clock and displays weekday and numerical date side by side. The hour and minute hands are gold-tone with pale central inserts, matched by a slim central seconds hand. Their warm finish coordinates with the markers and calendar frame, while the high contrast against the dark dial keeps the indications easy to read. The calendar is one of the main practical features of the watch and gives the dial a familiar Seiko 5 identity.

Stainless steel case with polished bezel and tapered lugs

The confirmed stainless steel case has a smooth rounded body with a polished bezel and long, cleanly tapered lugs. The exterior shows light age-related surface wear under close inspection, but the overall shape remains crisp and the polished areas retain a bright appearance. The case proportions work particularly well with the 19 mm strap connection, creating a coherent profile that feels neither overly formal nor overtly sporty.

Compact crown and clean case-side profile

A small ridged crown sits at 3 o’clock and is tucked close to the case, helping preserve the streamlined side profile. Its discreet scale is typical of a watch designed for everyday automatic use, where regular manual winding is unnecessary. No crown signature is clearly visible in the supplied image, so the listing makes no signed-crown claim.

Blue leather strap with contrasting stitching

The watch is currently fitted with a blue leather strap with light contrasting stitching. Its tone complements the dial and gives the watch a coordinated appearance without overpowering the steel case. The strap is adjustable and is described separately from the confirmed original watch components. Its cream-colored stitching adds a subtle contrast and gives the watch a casual everyday finish without changing the original configuration of the watch head itself.

Caliber 7009 automatic movement and practical day-date use

The confirmed Seiko 7009 caliber provides automatic winding and powers the central time display together with the day-date complication. No unsupported jewel count, frequency or power-reserve figure is added. The watch is confirmed as serviced and fully operational, giving the mechanical specification practical relevance for everyday vintage ownership.

1990 Seiko 5 character with a less common dark-dial presentation

Produced in 1990, this example combines the established Seiko 5 formula with a more decorative dark-dial treatment. The mixed marker layout, gold-tone furniture and blue surface give it a noticeably different personality from more conventional silver or black Seiko 5 models. Collectors interested in the brand can browse our Seiko vintage watches with late-20th-century Japanese design for other references and dial variations from the era.
