Seiko Quartz Type II Square Ref. 7546-5020 - QHK130, October 1977, NOS
The green tag on this watch's bracelet links it directly to a period catalog. The QHK130 code and the ¥26,000 price on the tag correspond to the same model listed in Seiko’s Japanese catalog. Nearly fifty years later, the watch still bears the price tag from the time it was originally offered for sale.

The serial number 707523 on the case back dates this specific piece to October 1977. By this time, Seiko’s quartz watches were no longer merely a technical novelty; the Type II was part of an extensive collection that brought this technology into everyday use. Yet, the design of the Ref. 7546-5020 is far from ordinary. Measuring approximately 34mm in width and 41mm in length, the steel case frames the dial within a thick, stepped square bezel. A multi-link bracelet extends from both ends of the case, carrying this angular form onto the wrist.
From a distance, the dial appears white; upon closer inspection, a pattern of small, interlocking curved lines covering the surface becomes visible. Applied indices with dark centers and the hands stand out clearly against this texture. The wide metal frame surrounding the day-date window at the 3 o'clock position extends the case's sharp lines into the dial itself. Meanwhile, the applied quartz emblem and "TYPE II" lettering at the 6 o'clock position clearly reflect the watch's identity from that era. Inside lies the four-jewel Calibre 7546A. This quartz movement, which powers the day and date display, is rated in Seiko’s technical specifications from that era as having an accuracy of ±15 seconds per month. The separate circular battery hatch on the caseback is an easily visible detail that highlights how the case was specifically engineered for a quartz movement.
What makes this particular example especially impressive is its NOS (New Old Stock) condition. The Seiko-signed steel bracelet and clasp have been preserved along with the watch, including the original Japanese price tag and a secondary Seiko hangtag. The catalog listing for the QHK130 (priced at ¥26,000) corresponds to the price tag still attached to the bracelet. The Seiko box shown in the photos accompanies the watch; however, it is not presented as the original box specific to this model.
Final Thoughts
For this Type II, 1977 is not merely a date read from the caseback; it is evident in the case angles, the textured white dial, and the ¥26,000 tag still attached to the bracelet. Through this unused example, the QHK130 illustrates an era when Seiko refused to compromise on design while bringing quartz technology into everyday life.
