Seiko 5 Actus SS, reference 6106-7440, a 1970s automatic men’s watch in stainless steel with a 40 mm cushion case, white dial, steel band, JDM Kanji/English day-date and hacking seconds on Caliber 6106C with 25 jewels, in very good condition with minor signs of wear.
Description from the seller
This Seiko 5 Actus SS, reference 6106-7440, is a distinguished example of Japanese watchmaking from the height of the mechanical era.Manufactured in January 1970 by the Daini Seikosha (Kameido factory), this timepiece represents the high-quality standards produced for the Japanese Domestic Market (JDM). The "SS" designation stands for "Second Setting," highlighting the hacking feature that allows the second hand to stop for precise time synchronization—a premium function at the time.
The watch features a robust stainless steel case with a unique cushion shape, typical of the 1970s aesthetic. The silver sunburst dial is clean and sophisticated, adorned with applied baton indices and the iconic "5 Actus" logo. It is powered by the reliable Caliber 6106C, a 25-jewel automatic movement known for its durability and the convenient push-button quickset for both day and date. The calendar wheel displays days in Kanji and English, a sought-after feature for collectors of vintage JDM Seikos.
Designed for versatility, this piece transitions seamlessly between casual and formal settings. Its 40mm case width (43mm lug-to-lug) offers a substantial yet comfortable presence on the wrist. The watch retains its original stainless steel bracelet, preserving its authentic vintage character. While fully functional, this 50-year-old timepiece is a testament to Seiko's enduring engineering philosophy.
