Konstantin Chaykin Brings Atomic Heart’s Ballerina Twins To The Wrist
The new Konstantin Chaykin x Atomic Heart limited edition transforms the game’s iconic Left and Right Twins into two mechanical watches, each limited to 69 pieces and powered by the manufacture’s K.18-25 calibre.
Konstantin Chaykin has never been particularly interested in conventional watchmaking.
His watches have drawn inspiration from mythology, portraiture, cinema and fine art, often turning the dial itself into a character.
The latest project takes that idea somewhere entirely different.
Created under official licence from Atomic Heart, the new limited edition brings the game’s instantly recognisable Left and Right Twins into mechanical form.
Each version is limited to 69 pieces and priced at CHF 20,000.
From Atomic Heart To Mechanical Watchmaking
Developed by Mundfish, Atomic Heart takes place in an alternative Soviet Union in 1955 — a retrofuturistic world where advanced technology, robotics and faith in scientific progress gradually give way to catastrophe.
Among its most recognisable characters are the Twins.
Serving as personal bodyguards to Professor Dmitry Sechenov, the two humanoid robots stand more than two metres tall, yet move with the controlled grace of ballet dancers.
Their movements were based on those of a Bolshoi Theatre ballerina, translated into the digital world through motion-capture technology.
The Twins combine metallic, robotic forms with movements derived from ballet, creating one of Atomic Heart’s most recognisable visual identities.
Their metallic bodies, golden braids and red forehead stars have since become some of the defining visual elements of the Atomic Heart universe.
For Chaykin, that made them natural material for another character-driven watch.
Two Watches, Two Personalities
The collaboration is offered in two distinct executions.
The Left Twin appears as a black silhouette against a deep red background.
Its dial uses a variation of grain d’orge guilloché, arranged to resemble the folds of an open fan.
The Right Twin is rendered in silver against a graphite background, with golden applied guilloché elements representing her cropped cardigan.
Straight radial lines extend downwards from behind the character’s head.
The Left Twin appears as a black silhouette against red, with guilloché inspired by the folds of an open fan.
The Right Twin combines a silver-toned figure with graphite and applied golden guilloché details.
Across both watches, abrasive-blasted surfaces, lacquered relief and polished applied components create a deliberately layered dial.
Two synthetic rubies mounted in gold-plated brass serve as pointers for the rotating hour and minute discs.
Positioned on the Twins’ chests, they become part of the characters rather than reading as conventional watch hands.
Even the Konstantin Chaykin logo has been integrated into the composition, appearing around the neck like a pendant.
The Moon Becomes The Face
One of the most distinctive elements sits at the top of the dial.
Instead of a conventional face, the Twins are given an oversized moon-phase display.
The proportions of the light and dark sections gradually change as the disc completes one revolution every 29.5 days, corresponding to the synodic month.
An oversized moon-phase display forms the Twins’ “face”, protected beneath its own sapphire crystal.
The moon phase is protected by a separate sapphire crystal.
Above it sits an applied synthetic ruby star, while the character’s golden braid is recreated in gold-plated brass.
Moving the moon phase to such a dominant position required Chaykin to rethink the familiar architecture of his character watches.
The rotating hour and minute discs have therefore been moved lower on the dial, requiring significant changes to the manufacture’s signature display module.
A 40mm Titanium Case
Despite the amount of visual information, the watch remains relatively compact.
The titanium case measures 40mm in diameter and 12.9mm thick.
It is constructed from 30 components and combines polished surfaces with directional brushing.
A slim bezel leaves as much room as possible for the multi-level dial architecture.
The single crown remains at 3 o’clock, while the caseback is secured by six screws and incorporates a sapphire crystal window.
The 40mm titanium case uses a slim bezel to give the multi-level dial architecture as much visual space as possible.
Each watch is delivered on an exclusive fabric strap with a titanium pin buckle produced by Konstantin Chaykin.
The K.18-25 Calibre
Both versions use the same K.18-25 automatic calibre.
At its foundation is the Swiss-made La Joux-Perret G200, modified exclusively for Konstantin Chaykin.
On top sits the manufacture’s proprietary display module, comprising 68 components.
The completed movement measures 34.5mm in diameter and 7.9mm thick including the module.
It runs at 28,800 vibrations per hour, contains 30 jewels and provides approximately 68 hours of power reserve.
The K.18-25 combines a modified La Joux-Perret G200 base movement with a 68-component in-house display module.
The complication set itself is relatively restrained.
Hours and minutes are indicated through Chaykin’s rotating-disc system, while the upper display handles the moon phase.
The complexity lies less in the number of traditional complications and more in how those indications have been reorganised to create the character.
A Watch That Appeared In The Game First
There is another layer to the collaboration.
Before the physical watch had even been revealed, it had already appeared inside the Atomic Heart universe.
The model can be seen on the wrist of Professor Lebedev in Blood on Crystal, the game’s final story expansion, released on April 16, 2026.
That makes the watch an unusual bridge between the digital and physical versions of the project.
The watch appeared first inside Atomic Heart, worn by Professor Lebedev in the Blood on Crystal expansion.
For most collaborations between watchmakers and entertainment properties, the product comes first and the storytelling follows.
Here, the sequence is reversed.
The watch existed in the fictional universe before collectors could buy it in the real one.
69 Pieces Of Each Twin
The Konstantin Chaykin x Atomic Heart Left Twin and Right Twin are each limited to 69 examples.
That means total production across the collaboration will amount to 138 watches.
Both versions are priced at CHF 20,000.
At first glance, this is one of Chaykin’s more playful projects.
But it also fits neatly within the broader development of his work.
The Wristmons concept has always relied on turning mechanical indications into recognisable characters.
Here, the character already existed.
The challenge was to make it mechanical.
And with the Twins, Chaykin has found a subject that feels unusually compatible with his own world: part machine, part character and deliberately somewhere between charming and unsettling.
