1974 Seiko Chronograph (Ref. 6138-0030) "Kakume"

The Kakume or “Square Eyes” Seiko automatic chronograph is powered by the revered Seiko cal. 6138 movement and beloved by enthusiasts for its oddball design and color scheme. Featuring large, and square, sub-dials at the 12 and 6 o’clock positions on the dial, the ref. 6138-0030 also features a quickset day and date complication. This very original Seiko Kakume example is very well preserved and comes on its original Seiko “fishbone” bracelet.

Because Seiko made so many varieties of chronographs at the time, and because they were on the more affordable end of the watch spectrum, many of the remaining 70s chronographs saw their fair share of rugged use, revealing their age and decades of use. However, this piece is in excellent condition for a chronograph of that era.
