The Louis Erard x Konstantin Chaykin Time-Eater Returns with an Appetite and a Tourbillon Worn & Wound

The Louis Erard x Konstantin Chaykin Time-Eater Returns with an Appetite and a Tourbillon

Many watches are designed to perform specific tasks or serve specific purposes beyond telling the time. Divers have bold markers and ratcheting bezels, pilot watches are oversized and might include a second time zone, track watches feature chronographs or tachymeters, etc, and then, there’s the Louis Erard x Konstantin Chaykin Time-Eaters. Featuring a giant eyeball for the hour hand, a spinning set of teeth for the seconds, and a double-sided arm that’s giving a one-finger salute, they don’t seek to fulfill a practical purpose. Instead, I’d classify them as “memento absurdum,” which is to say, objects that remind you of the absurdity, whether in life or watch collecting. If you’re thinking, “Now, wait a second, didn’t they just come out with a new Time Eater like a few days ago?” you’d be correct. A 42mm model with a navy blue chapter ring and a darker silver than previous versions, it was a handsome, if iterative, addition. But the Time-Eater is back once again, this time with a substantial change: it now has a tourbillon. This isn’t the first time we’ve seen Louis Erard use a tourbillon movement, specifically the “affordable for a tourbillon” BCP T02 by Olivier Mory, which appeared on a few of their Alain Silberstein collabs. The Time-Eater Tourbillon (TET from here out) is basically a reedition of one of the first two Time-Eaters, which was initially introduced in either a 39mm case with a purple chapter ring, or a 42mm case with a green ch...

Greubel Forsey’s Balancier Contemporain Exits with a Steel Final Edition

Greubel Forsey bids farewell to what was once its smallest watch, the Balancier Contemporain, with a final edition in stainless steel with a blue dial. The brand aims to finish the run of 33 watches later this year, after which the Balancier Contemporain will be no more, marking the end of its just-under-40 mm case. Notably, this is not a move away from mid-sized watches; in fact, the brand intends to double down on them with future launches. Initial Thoughts When launched in 2019, the Balancier Contemporain was the Greubel Forsey’s smallest watch – relatively speaking. The brand’s quality may be irreproachable, but wearability is another matter – several of its watches are well over 44 mm – and as consumers’ tastes gravitate back to mid-sized watches, Greubel Forsey was arguably in a tricky position with its near pocket-watch-sized calibres. But the brand was prepared for that. Just last year, Greubel Forsey set a new direction with the Nano Foudroyante EWT, a flyback chronograph (and flying tourbillon with lightning seconds) that was just under 38 mm in diameter and 10.5 mm thick. And even before that, the Convexe sports model cases already helped wearability massively – I’d even say the nominally larger Balancier Convexe and Double Balancier Convexe wear better than the Balancier Contemporain. So while the Balancier Contemporain is still a great watch, I’m not sad to see it go. As Greubel Forsey transitions to small-diameter watches, I expect to see it...

Louis Vuitton’s Jacquemart Pocket Watches Journey Around the World SJX Watches

Louis Vuitton’s Jacquemart Pocket Watches Journey Around the World

Translating as “Stopovers Around the World”, Escale Autour du Monde is Louis Vuitton’s collection of unique and lavish minute repeating pocket watches. The collection now counts two watches: Escale en Amazonie that depicts the heart of the rainforest, while the just-launched Escale Au Pont-Neuf is set just outside Louis Vuttion’s headquarters in Paris. Each timepiece is unique and powered by a new, purpose-built repeating movement with automata, also known as jacquemart, tourbillon, and an eight-day power reserve. Aside from watchmaking complications, the pocket watches also boast elaborate decoration, namely enamel and hand engraving, encapsulating the many crafts and skills possessed by La Fabrique du Temps (LFT), the Louis Vuitton manufacture in Geneva. The LFT AU14.03 Notably, the Escale Autour du Monde is actually Louis Vuitton’s second haute horlogerie pocket watch offering. The collection follows last year’s Asnières-themed pocket watch that was actually powered by a wristwatch repeater movement. The pocket watches of Escale Autour du Monde retain the same 50 mm diameter as the Asnières but with the LFT AU14.03 calibre within was developed from the ground up as a pocket watch movement. Escale en Amazonie (left), and Escale Au Pont-Neuf Initial thoughts Usually, modern pocket watches either rely on wristwatch movements (like the Escale à Asnières from last year) or near-century-old ebauches completed in the modern day. Louis Vuitton didn’t take th...

Louis Erard & Konstantin Chaykin Bid Farewell to the Time Eater with a Tourbillon

Having collaborated on several iterations of the affordable “Time Eater” regulator, Louis Erard and Konstantin Chaykin now close the chapter on the model with something more complicated. The Time Eater Tourbillon Louis Erard x Konstantin Chaykin tells the time regulator style – retaining the trademark “eyeball” hours from the Russian independent’s Wristmon series – but inside the “mouth” is a one-minute tourbillon. At CHF19,900, the Time Eater Tourbillon is pricier than the earlier time-only models, but still relatively accessible as such things go, thanks to a no-frills, but Swiss, tourbillon movement inside. Initial thoughts I liked the original Time Eater regulator because the design captures the Konstantin Chaykin style but makes it affordable at about a fifth of the price of a Wristmon. The Time Eater Tourbillon is less affordable, but still priced a little less than a Wristmon, so it is still a value proposition. More broadly, it’s a good thing that Louis Erard and Konstantin Chaykin are ending the Time Eater series. After three time-only regulator launches and this tourbillon, the concept has probably reached an optimal point of just enough and not overexploited. Rolling eye whimsy The Time Eater Tourbillon will be available in two variants: a green-accented model as pictured here that’s limited to 78 pieces, and one in blue that’s limited to 28. The former will be available from Louis Erard and its retailers, while the latter will only be so...

Biver’s Latest Carillon Tourbillon is All About Discretion

A subtler version of its flagship model, the Biver Carillon Tourbillon Signature Series looks almost like a time-only watch. It does away with the dial cutout for the tourbillon, leading to a more toned-down appearance for the complicated watch that combines a three-gong carillon repeater with a tourbillon. Notably, the new model is also available in a two-tone configuration of titanium and 18k rose gold. Initial thoughts Watchmakers usually highlight the tourbillon, putting the regulator front and centre of the dial (and charge a lot more for the mechanism too). Back in 2023, Biver made its debut with a tourbillon minute repeater,  which proudly displayed the tourbillon at six o’clock. Now the brand has reprised the model, but conceals what was the main showpiece on the dial. The two models are delivered with a set of cufflinks, material-matched to the watch The closed dial plainly conceals the tourbillon underneath. And due to the movement’s construction, the tourbillon can’t be seen from the case back either - making for a confusing sight. The end result is a very understated timepiece that doesn’t reveal itself easily, or much at all. In fact, the apparent simplicity is underlined by the dial, which is almost identical to that of the time-only Automatique. It features the same brushed circular sectors and micro relief minute track have become staple design elements of the brand. Were it not for the repeater slide, one would even be tempted to assume this is...

Introducing - The Breguet Classique Tourbillon Sidéral 7255 Celebrates the Brand’s 250th Anniversary

It will come as no surprise that the fourth instalment of Breguet’s 250th-anniversary celebrations honours Abraham-Louis Breguet’s most celebrated invention: the gravity-defying tourbillon. Following the Souscription, the Seconde Rétrograde and the Type XX Chronograph, the release of the latest celebratory watch coincides with the day and month Abraham-Louis Breguet obtained a patent for his tourbillon […]

Breguet Unveils First-Ever Flying Tourbillon with Tourbillon Sidéral 7255

Breguet celebrates a milestone by looking to the stars with the Classique Tourbillon Sidéral 7255, which is the brand’s first flying tourbillon and also dressed up with an aventurine enamel dial. The Tourbillon Sidéral is the brand’s latest anniversary edition – and the most complicated so far – coming after the Classique Souscription and more recent Type XX 2075BH. Initial Thoughts Abraham-Louis Breguet’s workshop only built between 40 to 49 tourbillons in his lifetime, explaining the mythical rarity of the mechanism in historical watchmaking. Now more tourbillons are built in a single day – possibly even by a single brand – than during Breguet’s entire lifetime. Consequently, the tourbillon is no longer regarded with the reverence it enjoyed for centuries. Tourbillons aren’t inherently special today, but still have appeal when executed well; the whole of the parts can be more than the sum of the parts. The Tourbillon Sidéral is executed well and appealing. Flying tourbillon aside, the rest of the watch is very good, though not ground breaking. As with Breguet’s other 250th anniversary models, the Tourbillon Sidéral is more interesting aesthetically than technically since the movement is derived from the longstanding Lemania calibre. That approach will change as the year’s end approaches as Breguet has something bigger in the pipeline. For now, the Tourbillon Sidéral is an excellent watch that may suffer under the weight of expectations, but per...

In-Depth: A Guide to Every Equation of Time Watch by A.-L. Breguet

Abraham-Louis Breguet (1747-1823) stands among the most revered names in horology, celebrated for innovations that shaped modern watchmaking. While his tourbillon, self-winding mechanism, and anti-shock system are widely acknowledged, his work in astronomical timekeeping, particularly equation of time (EOT) watches, remain one of Breguet’s most intricate yet less-explored achievements. With 2025 marking the 250th anniversary of his birth, this guide offers the most comprehensive study of every known EOT timepiece made during his lifetime, including pocket watch no. 160 “Marie Antoinette”, expanding on our prior analysis of the complication (in parts I and II). No. 160 as pictured at the recent exhibition in London’s Science Museum. Image – Baruch Coutts Looking at the stars Breguet operated in an era where precision timekeeping was dictated by astronomy, and his workshop, positioned at the heart of Paris’s scientific and commercial networks, was uniquely placed to serve scientists, navigators, and royalty who required accurate solar and mean time readings. Rather than settling on a single method for displaying and correcting the EOT, he explored multiple mechanical solutions, refining some while revisiting earlier ideas when necessary. His approach does not follow a strictly linear evolution but instead reflects a dynamic cycle of innovation, mechanical experimentation, and adaptation. Breguet’s cam-driven system with feeler to indicate EOT, as found in pocke...

Vacheron Constantin’s Temporis is a Unique Double Complication

Les Cabinotiers is Vacheron Constantin’s programme dedicated to one-off and special-order watches. The latest to emerge from the workshop is the Les Cabinotiers Temporis Duo Grand Complication Openface, a large, complicated watch with an intricate calibre and an unusually modern, clear sapphire dial. The look is more contemporary than usual for a Les Cabinotiers grand complication, thanks to both the sapphire dial with its off-centre displays and a monochromatic grey finish on the movement. An evolution (and stylistic upgrade) of the solid-dial Les Cabinotiers Minute Repeater Tourbillon Split-Seconds from 2022, the Temporis is underpinned by a base movement that features a minute repeater and tourbillon; on top sits a traditionally constructed split-seconds chronograph mechanism that is paired with the calibre in an unconventional manner. The layers inside the cal. 2757 S of the Temporis Initial thoughts Twenty twenty-five has been good for Vacheron Constantin in terms of complicated watches – the brand started the year with the Solaria, the most complicated wristwatch ever made, and has followed up with the Temporis. In comparison to the Solaria with 41 functions and a price tag in the mid-millions, the Temporis is simple and affordable, but still impressive. Though it is largely identical in terms of the movement to the 2022 model with a solid dial, the Temporis offers a lot more visually with its open dial. Though the look is modern – compare this to the baroque B...

    So the rotating cage just averages out gravity's effect on the balance wheel across the full rotation? That's actually elegant. Makes sense why these cost so much.
