Konstantin Chaykin Breaks the Record for World's Thinnest Mechanical Watch

For many years, the world’s leading watchmaking companies have been competing to produce the thinnest mechanical watches. Prestigious brands such as PiagetBulgari, and Richard Mille have been at the forefront of this race, with Bulgari securing a prominent position, dominating various categories. Recently, Bulgari made headlines by reintroducing its ultra-thin minute repeater during the first day of the Geneva Watch Days. Piaget previously held the title for the thinnest tourbillon watch at the Watches and Wonders event.

However, a new contender has emerged from Eastern Europe. Russian watchmaker Konstantin Chaykin unveiled a prototype that puts him at the forefront of the ultra-thin watch category.

Introducing Horage Unveils Its Revolution 3 MicroReg Timepiece

A watch with a revolutionary innovation in precision adjustment

Innovations in watchmaking are rare these days, especially in the realm of mechanical movements. While companies focus on developing new materials and designs, few introduce novel movement technologies. However, independent companies, like the young Swiss manufacturer Horage, are an exception. Horage, capable of producing nearly every component of its watches in-house, has demonstrated this innovative spirit with its latest release, the Microreg.

Horage, based in Biel/Bienne, was founded in 2007 by Andi Felsl and Tzuyu Huang. The brand is known for its high-quality mechanical watchmaking, contemporary design, and innovative technology. Their first in-house caliber, the K1, launched in 2015 after years of development, exemplifying their commitment to precision and modularity.

Imagine if a watch owner could easily regulate a watch precision. This is precisely what Horage and Miniswys offer with their Microreg system.

The Microreg is a small metal piece, sandwiched between two gold-coated ceramic pieces, which reacts to an external electromagnetic pulse to make micro-adjustments to the watch's regulating organ. Essentially, it performs the function of a watchmaker from within the movement itself. Regulation involves adjusting and setting the mechanical movement to run with minimal deviation.

Brands that prioritize high accuracy often have their movements tested and certified by independent organizations like METAS or COSC. Others, such as Rolex with its Superlative Chronometer, perform their own certification processes. Omega recently announced the establishment of the Laboratoire du Precision, which will provide chronometer testing services for all watch brands and movement manufacturers and will operate independently under the Swatch Group umbrella.

The accuracy of a mechanical wristwatch is crucial, constituting a significant portion of a watch’s production costs. Achieving higher accuracy requires higher-quality parts because any irregularity in the system, including material used, tolerances, and surface quality — affects the movement's precision. Manufacturers must ensure that escapement parts match perfectly to achieve the correct balance wheel frequency, which is essential for solid regulation. This involves ensuring the regulating mechanism is of sufficient quality to enable high accuracy, and watchmakers must carefully adjust each movement.

Regulating often involves changing the active length of the mainspring by rotating a regulating organ within the escapement. Even the slightest rotation of this organ can cause a one-second difference in accuracy over 24 hours. What makes this invention worthy of respect for mechanical watch enthusiasts is that the watch maintains the fact that its engine is completely mechanical, with no electrical parts inside it. To avoid this, the electronics are placed in a small device that is connected to the watch through two connection points on the side of the case.

The Horage Revolution 3 Microreg features a 316L stainless steel case with a diameter of 41 mm and a height of 10.5 mm. The domed sapphire crystal provides excellent durability and scratch resistance, with an anti-reflective coating ensuring optimal visibility in various lighting conditions. The caseback also includes a sapphire crystal, offering a clear view of the timing display hands as the watch design is inverted, and the case is water-resistant to 100 meters.

Horage has chosen to highlight the movement and MicroReg technology uniquely by placing the movement on the front and the traditional analogue time indication on the back of the watch. The main time display is presented on a rotating disc, with time indication read at the 6 o'clock position, enhanced with Swiss Super LumiNova for excellent legibility at night.

The dial side features the micro-rotor at 3 o’clock, above which is the MicroReg device. The movement is showcased in peacock blue with the signature K2 grid pattern and Côtes de Genève finishing. The sapphire exhibition caseback displays the secondary time indication with an hour disc and independent minute and center seconds hands. The edge of the caseback includes inscriptions, such as “Quest to Zero,” Horage’s slogan referring to their goal of achieving a deviation of 0 seconds per day with the MicroReg.

Powered by the brand’s K2 Micro-rotor movement enhanced with MicroReg technology, the watch features a gold-plated tungsten rotor and vertical brushing that matches the case. The anti-magnetic silicon escapement and hairspring, along with COSC chronometer certification, add to its resiliency and reliability.

The MicroReg technology utilizes small electromagnetic fields acting on micro-motors to adjust the balance spring's active length by moving the adjusting pin in nanometer increments. This technology allows precise timing adjustments, adding or subtracting 0.1 seconds to the watch's timing variance at the push of a button.

The watch comes with an FKM rubber strap and a stainless steel pin buckle. The Horage Revolution 3 MicroReg is expected to take 24 months to complete, with delivery anticipated in late summer 2026. It is priced at CHF 3,900, approximately 16,300 AED.
