The Konstantin Chaykin Wristmons Joker Classic presents an expressive anthropomorphic face with twin discs marking time. Hours rotate on the left disc while minutes turn on the right. Across the lower dial, a crescent aperture forms a smiling mouth, housing a moon phase indicator with a distinct red lunar disc serving as the tongue. The dial surface is embellished with relief guilloché rendered in grain de riz and pavé de Paris motifs.

Powering this display is the calibre K.18-18 self-winding movement. Built upon a modified Swiss La Joux-Perret G200 base calibre, it incorporates an in-house Konstantin Chaykin module composed of 72 parts. The mechanism operates with an anchor escapement, runs at 28,800 vibrations per hour, and contains 32 jewels across the assembly. It offers a 68-hour power reserve. Through the exhibition caseback, Côtes de Genève, hand-polished bevels, and an in-house skeletonised winding rotor are visible.

The case is machined from stainless steel, measuring 40 mm in diameter and 12.2 mm in thickness. Its bezel is engraved with playing card suit symbols alongside the letter J. Dual crowns flank the case: time adjustments occur via the crown at 3 o'clock, while the crown at 9 o'clock acts as the moon-phase corrector. Anti-reflective sapphire crystal protects the front, and the six-screw sapphire caseback provides water resistance to 30 metres.

On the wrist, the 40 mm proportions deliver balanced presence and versatile ergonomics. The curved lugs seat comfortably, while the dual-crown layout gives the silhouette distinctive symmetry. Every glance reveals shifting facial expressions created by the kinetic discs, ensuring a dynamic wearing experience supported by sturdy steel architecture.
