The Konstantin Chaykin Joker, launched in 2017, is the watch that gave birth to the Wristmons collection and dramatically increased the international visibility of independent watchmaker Konstantin Chaykin. Its principle is built around an anthropomorphic dial in which two eyes display hours and minutes on independent discs, while the smiling mouth contains a moonphase indication. This arrangement gives the face an expression that changes continuously throughout the day. The original Joker uses a 42 mm stainless-steel case, anti-reflective sapphire crystal and the automatic K07-0 calibre, built around an ETA 2824-2 fitted with the manufacture’s proprietary 61-component, eight-jewel module. The movement operates at 28,800 vibrations per hour and provides 38 hours of power reserve. Limited to 99 pieces, this first series becomes the starting point for a family that subsequently produces numerous Wristmons and several generations directly derived from the Joker.
The Joker concept is based on an idea that is extremely easy to understand but considerably more difficult to execute: using the actual time displays to form a human expression. The eye around 10 o’clock indicates the hours, the one around 2 o’clock the minutes, while the lower aperture becomes a mouth. The pupils therefore rotate independently and give the character a different look almost continuously. The face is not decoration added around the time display; the time indications themselves create the expression of the watch. This reversal between function and aesthetics largely explains the strength of the concept and its immediately recognisable character.
Hours are displayed by a disc completing one rotation every twelve hours, while the minute disc rotates once every sixty minutes. Reading the time simply requires noting the position of each pupil against its surrounding scale. The process can seem confusing for the first few minutes, but the human eye adapts rapidly. The Joker replaces conventional hands with two circular regulator-style displays that become surprisingly intuitive after a short learning period. It nevertheless remains less instantaneous to read than a conventional three-hand watch, particularly when the pupils sit between major markings or lighting reduces dial contrast.
The mouth is a traditional moonphase driven by a 59-tooth wheel. As the disc changes position, the red tongue and Moon completely alter the expression of the character. A full moon can produce a broad smile, whereas another phase can make the face appear more restrained or sarcastic. The moonphase therefore works simultaneously as a horological complication and as an emotional mechanism capable of changing the Joker’s expression. This unconventional use of a classical complication matters because Konstantin Chaykin is not attempting to reinvent the astronomical principle itself but the way it can be integrated into a radically different graphic language.
The first Joker dial uses silvering, rhodium plating, lacquer and several relief decorations resembling traditional guilloché. The nose, eyebrows and surrounding textures structure the face without relying on plastic components. The bezel carries playing-card suits, extending the Joker theme beyond the dial itself. The combination of traditional finishing techniques with deliberately pop-inspired graphics forms a major part of the watch’s originality. It may appear amusing from a distance, but closer examination reveals brushed, polished, blasted and decorated surfaces that clearly place it within low-volume independent watchmaking.
The architecture also creates something rarely encountered in conventional watchmaking: certain times naturally produce particularly amusing facial expressions. When both pupils point towards the centre, the character can appear cross-eyed; when they face opposite directions, it looks distracted or surprised. The dial therefore generates thousands of visual combinations using nothing more than the normal progression of time. This ability to create an emotional relationship with the owner becomes the central principle behind the complete Wristmons collection.
The original Joker has a round stainless-steel case measuring 42 mm and approximately 13.7 mm thick according to the manufacture’s current specifications. The diameter is substantial for a watch dedicated only to hours, minutes and moonphase, but it provides enough room for the two large eyes. The crystal is anti-reflective sapphire and water resistance is 3 atmospheres, or 30 metres. The 42 mm format primarily serves the proportions of the face rather than attempting to create a conventional sporting wrist presence. Later generations demonstrate that the Joker identity can be retained successfully inside a reduced 40 mm case.
The watch uses two symmetrical lateral elements that visually become the character’s ears. At 3 o’clock sits the principal control for winding and setting the time. On the opposite side, the system associated with the module allows moonphase correction while preserving the symmetry of the design. Placing controls on both sides transforms a functional requirement into an essential part of the watch’s face. Viewed directly from the front, case, crowns, eyes and mouth therefore form a coherent whole rather than an anthropomorphic dial placed inside a generic case.
The original strap is purple alligator with calfskin lining and green stitching, a deliberately bold choice reflecting colours traditionally associated with the Joker character. A stainless-steel pin buckle keeps thickness under the wrist relatively low. The strap contributes significantly to the personality of the watch and can dramatically change its level of visual exuberance. A black or dark configuration makes the case easier to wear, whereas purple, green or red straps used across different series emphasise its theatrical side.
The 30-metre water-resistance rating is a genuine practical limitation. The watch can tolerate ordinary splashes when properly maintained but is neither intended for swimming nor deliberate immersion. Its leather strap further reinforces this purpose. The Joker should be considered a playful collector’s dress watch rather than an all-purpose watch designed for every activity. On a pre-owned example, a pressure test remains sensible even when the owner has no intention of using the watch in water.
The 2017 Joker uses automatic calibre K07-0. Its mechanical base is the widely proven Swiss ETA 2824-2, onto which Konstantin Chaykin installs an indication module entirely developed by his manufacture. The complete movement measures 31.5 mm in diameter and 7.6 mm thick including the module. The real invention in K07-0 lies in the module that converts conventional mechanical rotation into two orbital indications forming the eyes of the character. Using a proven base movement simultaneously allows development resources to be concentrated on this specific complication.
The module contains 61 components and eight jewels intended to reduce friction. Combined with the 25 jewels of the base movement, the total reaches 33. Frequency is 28,800 vibrations per hour, or 4 Hz, and power reserve is 38 hours. The manufacture states accuracy of approximately plus or minus 15 seconds per day for this generation. The 38-hour autonomy is modest by current standards but remains consistent with the ETA architecture used for the original development. A Joker left unworn for two complete days is therefore likely to require resetting.
The moonphase disc is driven by a 59-tooth wheel, a classical architecture providing approximately two lunar cycles per complete rotation. The module nevertheless has to preserve precise visual coordination between both eyes and the mouth because even a small positional error immediately changes the expression of the character. The Joker mechanics are less spectacular than a tourbillon in pure complication terms but require considerable geometric precision to maintain correct alignment across all three displays. This principle helps explain why Chaykin subsequently develops several generations of specialised modules as Wristmons become increasingly complex.
The movement is automatic but also supports manual winding through the crown. This is convenient because a stopped watch can be restarted directly without shaking it or wearing it for several minutes. The absence of a date also avoids any additional calendar-setting procedure. Everyday operation is therefore remarkably straightforward despite the unconventional appearance of the display. The owner only needs to spend additional time synchronising the moonphase after an extended stop if astronomical accuracy of the smile is desired.
(2017) Konstantin Chaykin Joker First 99-Piece Series:
The Konstantin Chaykin Joker K.07-0 Joker is unveiled at Baselworld 2017 and receives unexpectedly strong demand, with the 99-piece production rapidly reserved. Its 42 mm stainless-steel case surrounds a white-and-green face in which the eyes display hours and minutes and the mouth presents the moonphase. Automatic K07-0 combines an ETA 2824-2 with a proprietary 61-component module for a total of 33 jewels, a 4 Hz frequency and 38 hours of reserve. This reference becomes the template for the complete Wristmons collection. Its importance therefore extends far beyond its limited production: it introduces the anthropomorphic watch as a recurring horological language and gradually turns an experimental project into Konstantin Chaykin’s principal contemporary signature.
(2017) Konstantin Chaykin Joker Only Watch First Unique Piece:
The Konstantin Chaykin Joker Only Watch 2017 is created specifically for the Only Watch charity auction and marks the first participation of a Russian watchmaker in the event. Its case uses zirconium instead of stainless steel and retains the twin-eye Joker display and moonphase powered by K07-0. The solid zirconium caseback carries the Only Watch emblem and clearly separates the piece from the regular commercial series. Sold at auction in November 2017, it demonstrates very early that the Joker concept can become a platform for unique creations without losing its identity. Chaykin will repeatedly use this principle for later charity projects and collaborations, turning Wristmons into an experimental field as well as a commercial collection.
(2018) Konstantin Chaykin Joker Titanium Lighter Case:
The Konstantin Chaykin Joker Titanium K07-0.Ti03.01 transfers the concept into a 42 mm titanium case and becomes one of the first direct evolutions of the original Joker. Production is limited to 88 pieces. The darker and substantially lighter metal gives the character a less reflective appearance while noticeably improving comfort. The dial retains twin-disc time display and moonphase, with specific relief engine-turning inspired by decorative techniques associated with Fabergé. K07-0 preserves its 38-hour reserve and 33 jewels. This edition demonstrates that Chaykin intends to develop the Joker through materials and decorative techniques rather than simply reproduce the original series in alternative colours.
(2021) Konstantin Chaykin Joker Black Bet Roulette and Luminous Eyes:
The Konstantin Chaykin Joker Black Bet pushes the gaming theme into the world of roulette. Its 42 mm case is made from black-PVD stainless steel and the caseback carries an engraved roulette wheel. Only 18 pieces are produced, each numbered according to the actual sequence of black roulette numbers rather than from 1 to 18. The eye discs receive luminous treatment for the first time on a Joker, making them especially visible in darkness. The movement remains the automatic 4 Hz K07-0 with a 38-hour reserve. This series demonstrates how Joker language can support a complete narrative involving dial, case, individual numbering and caseback without changing the underlying mechanical architecture.
(2022) Konstantin Chaykin Joker Five New Complication:
Created for the fifth anniversary of the model, the Konstantin Chaykin Joker Five represents a much deeper departure. Case diameter drops to 40 mm and the dial becomes extensively openworked to expose the face mechanism. The moonphase disappears and is replaced by a retrograde day-of-the-week indication forming the smile. Calibre K09-0 uses a modified VMF 3002 base and its proprietary module contains 142 components and ten jewels; final specifications state approximately 50 hours of reserve. Production is limited to 38 pieces and the model is made under DC Comics licence. Joker Five proves that the anthropomorphic architecture can accommodate complications other than moonphase while preserving the instant identity of the character.
(2024) Konstantin Chaykin Joker Classic Return of the Original Face:
The Konstantin Chaykin Joker Classic is unveiled in April 2024 as a complete reinterpretation of the first Joker rather than a straightforward reissue. Its stainless-steel case drops to 40 mm and 12.2 mm thick, while the eyes remain close to the dimensions of the 2017 model, making the face appear even more expressive. New automatic calibre K18-18 uses a modified G200 base, a 72-component Joker module, 32 jewels and a 68-hour reserve. The caseback becomes transparent and reveals a rotor made by the manufacture. Two palettes are offered, one close to the historic white and green design and another light grey with burgundy accents. Regular production is limited to no more than 100 pieces per year, making the Classic the true contemporary successor to the original Joker.
(2024) Konstantin Chaykin Joker Fiat Lux Skeletonisation and Titanium:
The Konstantin Chaykin Joker Fiat Lux explores another direction with an extensively skeletonised dial exposing the display mechanism. Its titanium case measures 40 mm and 12.1 mm thick. Automatic calibre K18-21 uses a modified ETA 2892A2 and receives an 84-component Joker module; it operates at 4 Hz, has 29 jewels and provides 42 hours of reserve. Unlike Joker Five, the mouth returns to the classical moonphase. Visible surfaces combine silvering, black coating, Clous de Paris decoration, lacquer and polished components. The edition is produced in very small quantities for the Asian market. Fiat Lux demonstrates that dial transparency can expose the mechanics without abandoning the lunar smile that defined the first Joker.
(2025) Konstantin Chaykin Joker Iron Mask & Golden Mask Open-Face Mechanism:
The Konstantin Chaykin Joker Iron Mask and Joker Golden Mask become regular models in 2025 after several years of development. Their stainless-steel cases measure 40 mm and 12.78 mm thick, while the dial deliberately conceals very little of the mechanism. The eyes still indicate hours and minutes, but the mouth uses a retrograde day-of-the-week display. Automatic K09-1 is based on a modified G200, with 36 jewels, 68 hours of reserve and a 140-component module. Iron Mask receives cool rhodium-plated finishing whereas Golden Mask uses gilded bridges recalling traditional finishing on historical pocket watches. These models consolidate in 2025 the research begun with Joker Five into open Wristmons while delivering significantly greater autonomy and finishing sophistication than the original 2017 K07-0.
The 2017 Joker remains the most compelling option for a collector prioritising historical significance. It is the first appearance of the concept, the series that created Wristmons and the model referenced by every subsequent evolution. Its 42 mm case and 38-hour reserve nevertheless appear less modern today. The first Joker should therefore primarily be chosen for its founding role and rarity rather than practical performance. On the secondary market, dial condition, original box and documents, original strap and service history deserve particular attention.
Joker Classic is substantially more rational for regular use. Its 40 mm case is easier to wear, the modified G200 provides 68 hours of reserve and the transparent caseback finally allows part of the mechanics to be appreciated from behind. Its design remains immediately connected with the 2017 watch. Joker Classic is probably the best choice for someone wanting the original Joker experience today without the main technical limitations of the first generation. Its annual production ceiling remains low enough to preserve the handmade character of the watch.
Joker Five, Fiat Lux and the Mask models better suit collectors interested in the technical evolution of the concept. Joker Five and the Masks replace moonphase with retrograde weekday indication, whereas Fiat Lux retains the Moon while exposing much more of the mechanism. The open versions are the most interesting for someone wanting to understand how the module turns mechanical gear trains into facial expressions. They do, however, lose some of the graphic simplicity that gave the original white-and-green Joker such immediate impact.
Comfort varies significantly by generation. The 42 mm original remains quite wearable on an average wrist but has strong presence, whereas 40 mm modern cases correspond more closely with current preferences. Titanium further improves the experience on Fiat Lux and selected earlier editions. A try-on remains advisable because the two large eye apertures make the dial appear visually broader than its actual dimensions suggest. The symmetry of the lateral elements nevertheless helps balance the case effectively.
Finally, a Joker should not be chosen solely for rarity. Its real appeal comes from the enjoyment of watching expressions change throughout the day and accepting a slightly unconventional approach to reading time. Early generations also demand greater attention to servicing and module adjustment. The best Joker will generally be the one whose visual language continues to amuse its owner long after the initial surprise has disappeared. Other customers’ opinions are essential.
The Konstantin Chaykin Joker is one of the contemporary independent watches that has most successfully transformed a horological complication into a genuine character. Its founding 2017 idea remains remarkably simple: two discs become eyes displaying hours and minutes, while a moonphase becomes a smile capable of continuously changing the expression of the dial. The original K07-0 is comparatively conventional in its ETA base, but its proprietary module creates a language Chaykin subsequently develops through titanium, luminous displays, retrograde weekdays, open dials and modern movements offering up to 68 hours of reserve. Joker Classic now represents the most direct and practical interpretation of that idea, while Joker Five, Fiat Lux and the Mask models demonstrate how far the concept can evolve without losing its identity.
To compare comfort, ease of reading, accuracy, enjoyment of the anthropomorphic module and the real pleasure of living daily with this constantly changing face against extended owner experience, Dialicious customer reviews provide a particularly useful complement.
