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

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...

Greubel Forsey Reworks the GMT Balancier Convexe

Greubel Forsey has refined its GMT Balancier Convexe with improved wearability due to a slightly smaller case, while maintaining the model’s trademark three-dimensional rotating globe. This is paired with some subtle, but interesting tweaks to the movement itself, including a new, and more elaborately decorated, escape wheel. Initial Thoughts Since the original GMT in 2011, the three-dimensional globe has become a Grebuel Forsey signature. Time zone-related complications are a natural fit for a sports watch, so much so that the brand’s first sports watch was a GMT. The brand has built on the GMT concept through multiple iterations, but the current version is arguably the most focused, without a tourbillon (or four), to distract from the core idea. The latest GMT Balancier Convexe is essentially the same as the previous model, but more wearable. It’s still a large watch, but scaled down and also might lightweight. The added power reserve indicator is also appreciated, and in hindsight, it’s odd that the function was absent in the first place given the utility of a power reserve display on a manual-wind travel watch. The World on Your Wrist Grebuel Forsey’s sporty Convexe cases have always worn somewhat smaller than specifications suggest due to the lug-less design, and the curved sapphire crystal back, which allows the watch to hug the wrist. However, a large watch that wears well is still a large watch. For the new GMT, Grendel Forsey has trimmed the case diamete...

Up Close: Urban Jürgensen UJ-1 Tourbillon

Urban Jürgensen has been revived in fine style thanks to its investors and of course Kari Voutilainen. With the Finn in charge of watchmaking, the reborn brand made its debut with a trio of watches led by the flagship Urban Jürgensen UJ-1 Tourbillon. Inspired by the Oval pocket watch made by Derek Pratt for Urban Jürgensen, the UJ-1 is impressive in its execution, from construction to decoration. The quality is evident across the watch, which is unsurprising given Mr Voutilainen’s role in its conception and production. And the occasionally controversial lugs give an otherwise classical watch a distinct character. Initial thoughts The fine details of the UJ-1 are easily apparent in the metal. The movement decoration and construction are both impeccable, and so is the guilloche on the dial. But it is details like the engine turned case back and typography that give the UJ-1 that little bit of extra refinement. It is obvious from the photos, the movement quality is outstanding. Frosting, black polishing, chamfering, and so on – all are expertly accomplished. Moreover, all of the decoration is done in a traditional, often manual manner, rather than being mostly done by machine and then finished off by hand as is increasingly the case now. But finishing is merely the more obvious aspect of the appeal. The construction of the movement is equally impressive. It captures the style of the Oval pocket watch, including the three-dimensionality and clean aesthetics. Even though...

    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.
