Note: The “Kakume” is a highly collectable model in the 6138 range, and is named for its two square subdials (“Kakume” is Japanese for “Square Eyes”). This piece is a great example of the "Speed-Timer -0045T" late JDM version. The bracelet is original to the watch. *Please note one of the end links is Z039, which corresponds to the International version of this model.
