Detail
This is the only officially released wristwatch model themed after Kallen Kōzuki to date.
The right half of the index represents the fingers of the right hand of Guren Mk-II, the Knightmare Frame piloted by Kallen, featuring its distinctive sharp claws, while the left half represents the fingers of the left hand — each side differing in color and shape.
The upper part of the chronograph dial depicts the characteristic right palm of the Guren Mk-II. In addition, the Black Knights emblem, the organization to which Kallen belongs, is engraved on the dial.
The dial and strap are finished in red, while the case, crown, and buckle are black — symbolizing Kallen’s affiliation with the Black Knights.
Released in 2017 as a made-to-order, limited-production item, it has never been reissued since, and there is virtually no chance of a re-release. This remains the only Kallen model ever produced, and since owners rarely part with theirs, it seldom appears on the market. Moreover, finding one complete with all original accessories is exceptionally rare.
