Seiko 5 ACTUS Automatic – Ref. 6106-7470 – Black Dial with Blue Accent This is a vintage Seiko 5 ACTUS automatic wristwatch equipped with Seiko’s in-house Caliber 6106. The ACTUS line represents Seiko’s approach to creating a more expressive and youthful automatic watch during the late 1960s and early 1970s. While positioned as a practical daily watch, ACTUS models often featured bolder case designs and distinctive dial layouts compared to standard Seiko 5 models, making them highly recognizable today. This particular example features a black dial accented by a blue inner ring, a combination that strongly reflects Seiko’s early-1970s design language. The applied hour markers and clear minute track provide excellent legibility, while the overall balance of the dial gives the watch a sharp yet restrained character. The day-date display is positioned at 3 o’clock. On this watch: The date is adjusted by pushing the crown The day is adjusted by rotating the hands The case back is engraved with Seiko, Stainless Steel, and Water Resistant, along with the reference 6106-7470.
