Especially for the “Joker” and other models of the “Wristmons” collection Konstantin Chaykin developed a double-disc display for the hour and minute indications, as well as a moonphase indicator. In the construction and design of the movement, he was guided by the principles of haute horlogerie, despite the fact that the movement is hidden under an opaque dial. Konstantin Chaykin meticulously finished every part of the movement using classic techniques: perlage pearl textured grinding; fine longitudinal and circular grinding; abrasive blasting to a matte finish; a smooth handcrafted chamfer; engraving; polished screw holes, pins and jewels; spherical polishing of the axel tips; and galvanized rhodium plating. In total the module includes 8 jewels, designed to reduce friction, while the moonphase indicator is driven by a wheel with 59 teeth.
