Seiko 5 Actus SS JDM - (6106, 1970s)

Description: Vintage Seiko 5 Actus SS, Japan Domestic Market (JDM) version, from the 1970s. The Actus SS is one of the more elusive references in the vintage Seiko 5 family - the "SS" designation denoting Second Stop, Seiko's term for the hacking function that allows the seconds hand to stop when the crown is pulled, enabling precise time setting. A feature uncommon at this price tier in the 1970s and a mark of the Actus SS sitting above standard Seiko 5 production.

Powered by Seiko Calibre 6106 automatic movement with hacking mechanism. JDM specification confirmed by Kanji day wheel and Made in Japan caseback engraving. Original acrylic crystal present, showing honest age-related surface scratching. Original period-correct integrated bracelet intact - a distinctive and architecturally bold design characteristic of the Actus line that sets it apart from standard Seiko 5 variants. Day-date display.

Story of This Watch: A hard to find JDM Seiko 5 Actus SS surviving with original crystal and original bracelet - two components most examples of this age have long since lost. The Kanji day wheel confirms genuine Japan domestic market specification, making this a more collectible proposition than standard export variants.
