Remember the sensational ThinKing—a unique, ultra-thin watch with a jaw-dropping 1.65mm profile that stunned the world back in 2024? The competition was fierce, with renowned brands like Piaget and Bvlgari battling it out to create the finest piece of horology. Suddenly, Konstantin Chaykin stepped into the spotlight with his ingenious creation. Although the original ThinKing was just a prototype and never saw production, fast forward two years, and we welcome the Konstantin Chaykin ThinKing Mystery, boasting the same impressive thickness. This limited edition of just 12 pieces is now officially the thinnest mechanical production watch on the market—kudos to Konstantin Chaykin!

Interestingly, the original Konstantin Chaykin ThinKing prototype did find a buyer—in 2025, it fetched a whopping CHF 508,000 at Phillips auction. This one-of-a-kind piece was a true marvel of watchmaking complexity, marrying high-level craftsmanship with the whimsical charm reminiscent of the Joker. Replicating this innovative feat in a limited series involved a complete overhaul of the production process and an unwavering commitment to excellence, resulting in a breathtaking expression of groundbreaking horology with a playful twist.

Setting the Record: The ThinKing Mystery

Let’s make this official: the Konstantin Chaykin ThinKing Mystery is now recognized as the thinnest mechanical watch in the world. And this is not just another prototype; it’s a commercially available timepiece in a limited series of 12. Hats off to Konstantin Chaykin for securing this prestigious title while larger competitors like Piaget, Bvlgari, and Richard Mille were vying for it as well. Although the ThinKing Mystery is based on the original prototype, it introduces captivating new features.

When you see “Mystery” in the title, you can expect an enchanting mechanism that displays the time in an intriguing way. Imagine finite sapphire discs rotating gracefully within a watch that measures only 1.65mm thick—it’s nothing short of awe-inspiring! Konstantin Chaykin hasn’t just transformed a wafer-thin prototype into a market-ready watch; he has also integrated a compelling mystery element with fully transparent, time-indicating sapphire discs.

Joker-Inspired Design: A Glimpse Into the Eyes

In the ThinKing Mystery, the “eyes” are fully transparent, removing crossbars from their design. This concept pays homage to Chaykin’s Mystery 1000 Jewels, created in 2007 to honor the legacy of Jean-Eugène Robert-Houdin—an illusionist and inventor from the 19th century. Robert-Houdin designed a clock with a single hand that appeared to float thanks to a transparent disc, cleverly hiding the mechanism.

In the ThinKing prototype, the lateral drive delivered motion to wheels aligned on a central axis. Conversely, the ThinKing Mystery utilizes a lateral drive to rotate solid sapphire discs, each guided by three rollers. This innovation allows for efficient movement while preserving the mainspring’s energy, resulting in an enhanced power reserve of 38 hours—up from the previous 32 hours. The movement can be wound with a specialized tool and comes complete with an exclusive winding box.

Uncompromising Quality: A Mechanical Masterpiece

The ThinKing Mystery’s intricate movement epitomizes watchmaking finesse. In this design, the “case back” doubles as the mainplate, with the balance assembly laid flat. This innovative configuration features two interlocking wheels: the first controls the oscillation frequency, while the second acts as a roller that interacts with the pallet fork. A new addition is the ultra-thin barrel, reinforced with stiffening ribs for added durability.

Finishing each component is just as critical as manufacturing them. The finishing process demands precision; even the tiniest excess material can distort and compromise the entire assembly. Remarkably, both the case and caliber exhibit levels of Haute Horlogerie finishing. Stunning perlage and straight graining adorn the bridges and mainplate, while each bevel is painstakingly cut and polished by hand.

Each case undergoes around 40 meticulous routing checkpoints, ensuring precision to an astonishing degree—any deviation at the micron level could potentially disrupt the entire operation. This commitment to excellence mirrors the practices of aerospace engineering more than traditional watchmaking. Watchmakers carefully document and verify every parameter against stringent quality standards.

Speaking of the material, the alloy undergoes an extensive heat treatment to boost hardness and resistance against deformation. Mastery over the material and its interaction with tools is crucial, as even a minor error can affect the clearances, leading to instability in the movement.

The Slim Profile of an Icon

Describing the Konstantin Chaykin ThinKing Mystery as “thin” barely does it justice. With a staggering 1.65mm thickness, it almost defies categorization—how about we say it has “almost no profile”? This ultra-slim design doesn’t just contribute to its aesthetic appeal; it comes with a high-quality leather strap featuring resilient titanium stiffeners and elastic inserts. This strap is ingeniously part of the overall structure, helping to reduce stress on the case. While it may not be a “GADA” (Go Anywhere, Do Anything) watch, it’s designed to be worn without the constant fear of breakage.

As for the price tag of the exclusive 12 Konstantin Chaykin ThinKing Mystery watches? That’s still a bit of a mystery! Are you dying to know, or would you prefer it to remain as enigmatic as the watch’s inner workings? For the latest updates, be sure to check out Konstantin Chaykin’s official website.
