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 quartz chronograph. The stainless-steel case displays visible surface scratches, light scuffs and small marks, particularly around the polished bezel, case edges and lugs. These signs of wear are consistent with its age and contribute to its authentic vintage character.

The silver-tone dial retains an attractive appearance, featuring four carefully arranged subsidiary displays, applied baton hour markers and the distinctive celestial moonphase indication at 12 o'clock. The contrasting silver-grey subdials, fine black graduations and polished hands create an elegant and technically sophisticated composition.

The celestial display remains one of the most appealing features of the watch, with its dark blue background, decorative stars and contrasting moon imagery providing a distinctive visual accent.

The mineral crystal may present light surface scratches or small marks associated with previous use. The polished bezel also displays minor scratches and traces of handling consistent with the watch's vintage condition.

The stainless-steel case back shows visible surface scratches and signs of regular wear, while the engraved Seiko identification markings and reference number remain legible.

The generic leather strap complements the watch's classic appearance and accommodates a wrist of up to approximately 20 cm. The strap may show light creasing and signs of previous use.

The watch is supplied with a generic presentation box.

The individual electronic functions, including the chronograph, alarm and moonphase indication, have not been independently verified for accuracy or correct operation.

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.

Although the case back is marked "Water Resistant", 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 some of the most important technological developments in modern watchmaking. 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 timepieces.

Throughout the 20th century, Seiko became internationally recognised for its commitment to innovation, technical development and the continuous improvement of timekeeping accuracy. The company played a particularly important role in the development of quartz wristwatches, introducing technologies that fundamentally transformed the international watch industry.

In 1969, Seiko introduced the Astron, widely recognised as the world's first commercially available quartz wristwatch. This remarkable achievement marked a turning point in horological history, demonstrating the potential of electronic regulation to deliver exceptional precision and reliability.

During the following decades, Seiko continued to explore the possibilities of quartz technology. The brand developed increasingly sophisticated movements capable of incorporating chronographs, alarms, calendar indications and other complications within compact wristwatch cases.

The Seiko 7T36 calibre belongs to this fascinating period of Japanese watchmaking. Designed as a multifunction quartz movement, it reflects Seiko's ability to combine electronic precision with the visual richness traditionally associated with complicated mechanical wristwatches.

This particular Seiko Chronograph Moonphase represents an especially attractive interpretation of that philosophy. Its silver-tone dial features four subsidiary displays arranged in a balanced configuration, creating a sophisticated appearance reminiscent of traditional complicated timepieces.

The most distinctive element is undoubtedly the celestial indication positioned at 12 o'clock. Featuring a dark blue background, decorative stars and contrasting moon imagery, this display introduces a poetic and astronomical dimension to an otherwise highly technical wristwatch.

Throughout the history of horology, the moon has occupied a special place in the development of watchmaking complications. Long before the introduction of electronic movements, watchmakers sought to reproduce the changing appearance of the moon through intricate mechanical displays. Moonphase indications became symbols of craftsmanship, technical ingenuity and the enduring relationship between timekeeping and astronomy.

Seiko's interpretation brings this traditional inspiration into the world of quartz technology, combining a romantic visual element with the practicality of modern electronic watchmaking.

The chronograph function introduces a sporting dimension, allowing elapsed time to be measured through dedicated indicators. The integrated alarm adds another practical feature, reflecting the growing demand for multifunction wristwatches during the development of advanced quartz movements.

The additional calendar indication contributes to the complexity of the dial, while the carefully positioned subsidiary displays preserve a harmonious and balanced appearance.

Surrounding the dial is a polished stainless-steel bezel engraved with numerical graduations. This detail reinforces the watch's technical character and provides an attractive contrast to the refined silver-tone dial.

The 37 mm stainless-steel case reflects the balanced proportions associated with vintage Japanese wristwatches. Its dimensions provide an elegant presence on the wrist while allowing the numerous functions and subsidiary indicators to remain clearly visible.

The combination of polished steel, silver-grey dial elements and the dark blue celestial display creates a sophisticated colour palette. Paired with a classic leather strap, the watch offers a versatile appearance suited to both everyday wear and more formal occasions.

At its heart, the Seiko 7T36 quartz movement represents an important stage in the evolution of electronic horology. By incorporating multiple indications within a single movement, Seiko demonstrated how quartz technology could offer the visual complexity and functional versatility traditionally associated with elaborate mechanical watches.

Today, vintage Seiko multifunction chronographs attract enthusiasts who appreciate the technical creativity of Japanese watchmaking, the distinctive styling of earlier quartz generations and the individuality of watches produced during a period of rapid technological innovation.

With its elegant silver-tone dial, four subsidiary displays, celestial moonphase indication, chronograph functionality, integrated alarm and stainless-steel construction, this Seiko offers an appealing combination of vintage sophistication, technical ingenuity and enduring design.

A distinctive Japanese quartz timepiece that celebrates Seiko's pioneering spirit and the fascinating meeting point between astronomical inspiration, practical complications and precision watchmaking.
