Chaykin Made The Thinnest Mechanical Watch And Then Gave It A Magic Trick

ThinKing Mystery is 1.65 mm thick. Calibre K.23-3.1 lives in the caseback. Twelve watches. The thinness is the method. The mystery is the joke that survived the method.

Konstantin Chaykin put the sentence on his own page. Invisible thickness, tangible magic. The 1.65 mm record takes a new step. ThinKing, shown as a prototype at Geneva Watch Days 2024, is now ThinKing Mystery: a limited edition of twelve, industrialized rather than left as a unique stunt.

Case: 41 mm across, 1.65 mm thick. High-strength, high-precision alloy. 284 components. 12.1 grams without the strap. In-house calibre K.23-3.1, manual key winding, movement integrated into the case so the caseback is the mainplate. 54 jewels. Dual balance with a patented toothed coupling, 18,000 vibrations per hour. Swiss lever. One ultra-thin barrel, patented, 38 hours of reserve (the 2024 prototype sat at 32). Accuracy stated at −15/+20 seconds a day. Functions: mystery hours and minutes. Four sapphire crystals, 10.6 mm by 0.3 mm. Two sapphire discs, 10.6 mm by 0.2 mm. Leather strap with titanium stiffeners and elastic inserts, a patented build, because a watch this thin would crumple a normal strap against a wrist bone. Stainless buckle from the manufacture. Carbon and steel winding box, 47 by 43 by 9.2 mm, 30 grams, 112 parts, winding and setting plus a safety clutch. A 94 mm steel key, 26 parts, safety mechanism.

Thinness, in this house, is not a season. It is a constraint that Chaykin decided to keep after the prototype sold and the internet finished gasping. The mystery display is how he refused to let the constraint become a blank silver pancake.

Ultra-thin watchmaking eats hundredths. Brands with conglomerate labs have spent the last decade trading 1.80 for 1.75 for 1.70. Chaykin’s number is 1.65. He got there as an independent workshop that already made Joker faces and cinema clocks and pocket theater. The first ThinKing was a prototype with a palanquin carrier, the PalanKing, that turned the sliver into a 5.4 mm automatic package you could actually live with. That object went to auction. The Mystery edition is the attempt to prove the sliver can be a series.

Series, here, means twelve. Each assembled by the man whose name is on the dial space that barely exists. The case alloy is a hard, non-magnetic, high-precision mix described as space-industry stock in some briefings, nickel-family in others. What matters on the wrist is rigidity. At 1.65 mm a case is a suggestion unless the metal argues back. Sandblasting on the large open surfaces is extra stiffness, not décor.

The architecture is two-level. Gear train stacked so the vertical budget can stay a rumor. Case as calibre. If you pull the movement out you have dismantled the watch. That is the price of the number. It is also why a crown would have been a joke. There is no wall thick enough for a stem that behaves.

38 hours is still short next to a conventional three-day barrel. It is longer than the prototype. The barrel lost its traditional cover. The bridge got ribs. The arbor became an overrunning clutch with tungsten carbide balls. Those are workshop sentences. They exist because a record that cannot run until dinner is only a press photo.

arcane

Chaykin’s Wristmons taught people to read a watch as a face. Joker eyes. A grin that is a moon. ThinKing Mystery keeps the play and kills the printed cartoon. Two transparent sapphire discs carry the hour and the minute. They look unsupported. Rollers at the edges turn them. Three per indication in the technical tellings. You see time. You do not see a pipe rising through the center of the world.

That is why the model is Mystery and not only ThinKing. Nineteenth-century mystery clocks hid the drive so hands seemed haunted. Chaykin hid the drive so a 0.2 mm disc could live inside a 1.65 mm sandwich. The playfulness the brief wants is here. Not a mascot. A conjuring trick that had to survive a height limit tighter than two credit cards stacked with room to spare.

Four crystals protect two discs. The stack of glass is itself a dare. Sapphire at 0.3 and 0.2 mm does not forgive a clumsy press. The dual balance, two wheels on one plane with a toothed coupling, is how he asked isochronism to share the same stingy air.

The name is a pun. Think. King. Thin. Mystery is the second pun: you cannot see how, which is the oldest luxury in clocks.

No crown. Wind and set with the key in a slot on the back, or park the watch in the carbon box that winds and sets it and refuses to overwind. The box is heavier than the watch. That ratio is the whole project in one weigh-in. 12.1 grams of time. 30 grams of furniture to keep the time alive.

The strap is engineering. Titanium bones inside leather, elastic where a wrist flexes. A sliver this sharp would knife a conventional band into a hinge. Patent language exists because the strap is part of the movement’s survival, not an afterthought from a catalog.

Price sits in the upon-request column on some official language. Trade reports have used CHF 400,000. A Japan boutique listing printed a dollar figure north of half a million. Twelve buyers will know the invoice. The rest of us get the number that matters: 1.65.

Thinness is not a fad when the alternative is a thicker watch that does the same two indications. It is a fad when the only content is the caliper. Chaykin added a trick you can see from across a table. That is the argument. The record is the case. The mystery is why the case still looks like him.

Twelve watches. A key. A box. A polar-opposite of a tool watch that still asks to be worn, carefully, for 38 hours at a time. The king is thin. The thinking is the disc that should not be able to turn.
