Condition Report

Grade B – Good vintage condition, with visible signs of wear consistent with age.

The watch presents the characteristic signs of ageing and previous use expected from a vintage Japanese automatic timepiece. The stainless-steel case displays visible surface scratches, light scuffs and small marks, particularly around the bezel, case edges and lugs. These signs of wear are consistent with its age and contribute to its authentic vintage character.

The deep blue dial retains an attractive appearance, featuring applied rectangular hour markers, elegant silver-tone hands and the distinctive Seiko Automatic 25 Jewels signature. The dial presents subtle signs of ageing, including small marks and light discolouration, particularly around the outer edges and certain hour markers.

The acrylic crystal displays a clearly visible scratch near the 12 o'clock position, as shown in the photographs. Additional fine surface marks may also be present due to previous use. The scratch is a cosmetic imperfection consistent with the watch's vintage condition, and the acrylic crystal may be polished or replaced by a professional watchmaker if desired.

The framed day-date aperture at 3 o'clock remains an attractive feature of the dial, displaying the bilingual calendar configuration characteristic of many vintage Seiko automatic watches.

The original Seiko stainless-steel bracelet complements the rectangular case and preserves the distinctive design language of the period. Its geometric links feature alternating brushed surfaces and recessed decorative elements, creating a cohesive appearance with the case. The bracelet shows visible scratches and signs of regular wear consistent with its age and accommodates a wrist of up to approximately 20 cm.

The watch is supplied with a generic presentation box.

The long-term accuracy, power reserve and service history of the automatic movement have not been independently verified.

Please examine all photographs carefully, as they form an essential part of the condition report and provide the best indication of the watch's actual cosmetic condition.

The water resistance has not been tested and cannot be guaranteed. Contact with water should therefore be avoided unless the watch has been professionally inspected, pressure-tested and appropriately resealed.

Story & Heritage

The history of Seiko is closely connected with the evolution of modern Japanese watchmaking and the development of reliable, innovative mechanical timepieces. Founded in Japan in 1881 by Kintaro Hattori, the company developed from a small watch and clock business into one of the world's most influential manufacturers of precision watches.

Throughout the 20th century, Seiko established an international reputation for combining technical innovation, practical functionality and distinctive design. The company played an important role in making high-quality mechanical wristwatches accessible to a wider audience, while continuously developing its own manufacturing capabilities and movement technology.

One of Seiko's most significant achievements was its commitment to producing mechanical movements through an integrated manufacturing approach. By developing and manufacturing many essential components within its own production facilities, Seiko gained considerable control over movement design, quality and technical development.

During the 1960s and 1970s, Seiko introduced numerous automatic wristwatches that reflected the growing popularity of practical, self-winding timepieces. These watches combined dependable mechanical construction with modern styling, offering convenient everyday timekeeping without the need for regular manual winding.

The automatic movement became particularly appreciated for its practical simplicity. Powered by the natural movement of the wearer's wrist, it represented an elegant mechanical solution to everyday timekeeping, preserving the traditional craftsmanship of watchmaking while offering greater convenience.

The 1970s also marked an important period of stylistic experimentation within the watch industry. Traditional round cases increasingly shared the market with rectangular, cushion-shaped and angular designs inspired by contemporary architecture, industrial design and changing fashion trends.

Seiko embraced this evolution, producing a wide variety of watches with distinctive case shapes, colourful dials and integrated bracelets. These designs reflected the optimism and creativity of the period, when watchmakers explored new ways to combine mechanical engineering with modern visual identity.

This particular Seiko Automatic Day-Date is an attractive expression of that era. Its rectangular stainless-steel case features strong geometric lines softened by carefully shaped edges, creating a distinctive architectural appearance.

The deep blue dial provides a striking contrast to the silver-tone case and bracelet. Its rich colour adds depth and character, while the applied rectangular hour markers and slender hands maintain a clean, balanced and highly legible design.

The asymmetrical placement of the Seiko signature and automatic movement inscription introduces an interesting visual detail, distinguishing this watch from more conventional dial layouts. The arrangement reflects the creative freedom that characterised many Japanese wristwatch designs of the period.

The bilingual day-date display positioned at 3 o'clock adds both practicality and vintage charm. Calendar complications became increasingly popular during the development of automatic wristwatches, allowing wearers to consult the day and date directly from the dial without sacrificing the traditional mechanical character of the watch.

The presence of 25 jewels is another appealing technical feature. In mechanical movements, synthetic jewel bearings are used to reduce friction and wear at important contact points, contributing to the efficiency and durability of the movement.

The automatic winding system further enhances the watch's mechanical appeal. Through the movement of an internal rotor, energy generated by wrist motion is transferred to the mainspring, allowing the watch to operate without the need for a battery.

An especially attractive feature of this example is its original stainless-steel bracelet. Designed with broad geometric links and decorative recessed details, the bracelet complements the rectangular case and reinforces the integrated styling associated with vintage watches from the 1970s.

The relationship between the case and bracelet creates a cohesive visual identity, transforming the watch into a complete design object rather than simply a traditional wristwatch attached to a separate strap.

The 38 × 31 mm case dimensions reflect the distinctive proportions of vintage rectangular watches. Although more compact than many contemporary wristwatches, the angular construction and broad dial provide a confident wrist presence while preserving the elegant proportions associated with its period.

Today, vintage Seiko automatic watches are appreciated by collectors for their mechanical ingenuity, distinctive styling and important place in the history of Japanese horology. Examples featuring unusual case shapes, colourful dials and original integrated bracelets are particularly appealing to enthusiasts who value authentic period design.

With its deep blue dial, rectangular stainless-steel case, original geometric steel bracelet, bilingual day-date complication and 25-jewel automatic movement, this Seiko offers an attractive combination of vintage character, mechanical tradition and distinctive Japanese design.

A characterful vintage automatic timepiece that celebrates Seiko's innovative spirit and the bold aesthetics of an era when watchmaking combined practical engineering with creative freedom and enduring style.
