King Seiko Hi-Beat Ref. 5625-8001 - A Memento of Service in Tokyo
The King Seiko 56KS family represents one of the most distinctive product lines from the era when Seiko was vying for the pinnacle of mechanical watchmaking. However, the 5625-8001 model featured here is special for more than just its excellent condition; a significant part of its story has been inscribed on the caseback for nearly half a century.

The slim, silver-toned sunburst dial creates an aesthetic that is remarkably understated yet powerful, defined by long, faceted indices and sharp Dauphine-style hands. While the gold-tone case, indices, and framed date window maintain a cohesive design language, the KS/HI-BEAT emblem at the 6 o'clock position instantly establishes the watch's identity.
Inside beats the 25-jewel Seiko Cal. 5625A, clearly visible in the photographs. As one of the automatic Hi-Beat movements powering the 56KS family, the 5625A lies at the heart of the mechanical character that makes this era of King Seiko so compelling to collectors today.
Yet, the true story of this particular timepiece begins when we turn it over.
Three lines of Japanese text are engraved on the caseback:
昭和50年度
Shōwa 50 — 1975
永年勤続記念
Commemoration of long-term service
東京都職員互助組合
Tokyo Metropolitan Government Employees Mutual Aid Association
This engraving is not merely a decorative personalization; it is an integral part of the watch's history. The caseback itself bears witness to the fact that this King Seiko was awarded in 1975 by the organization serving Tokyo Metropolitan Government employees to commemorate years of dedicated service. This detail elevates the watch beyond being just an anonymous vintage piece. It was once presented to its owner in Tokyo after a long career; it has survived to the present day without the engraving being erased, the case altered, or its history erased.
Moreover, it comes with a truly impressive Seiko presentation box from the era that complements the watch's character. Its navy blue textured finish, gold-colored SEIKO lettering, and velvet interior harmonize almost perfectly with the watch's gold tones. The period-correct buckle featuring the KS logo further completes the watch's classic Japanese dress-watch aesthetic.
Looking back after nearly half a century, what makes this piece so appealing isn't just the clean dial, the beautiful King Seiko case, or the Hi-Beat movement.
It is the fact that the watch’s identity remains intact.
Final Thoughts
Engravings on vintage watches are sometimes viewed as flaws. Yet, there are engravings that, rather than diminishing a watch's value, imbue it with a unique history found in no other example.
The few lines of Japanese text on the back of this King Seiko preserve the memory of a specific year, an organization, and the appreciation shown at the end of a long career—all for nearly fifty years.
