Year in Review: Our Best Stories of 2025 SJX Watches
Patek Philippe ref 1518 Dec 24, 2025

Year in Review: Our Best Stories of 2025

Our 2025 coverage included original research and in-depth stories including CEO interviews, engineering explainers, behind-the-scenes manufacture visits, and hands-on features exploring the latest developments in modern horology. We’d like to thank our readers for their engagement and support, which continue to shape and sustain our work. Our founder SJX provided an in-depth study of the Breguet Sympathique No. 1, with exclusive insights from its creator François-Paul Journe. The story is notable not only for its technical reconstruction of the mechanism but also for clarifying how the Sympathique informed Journe’s earliest thinking as a constructor before launching his namesake brand. SJX also spent time with the people leading the industry. Interviews with Kari Voutilainen, Gregory Kissling, Ilaria Resta, and Marc Michel-Amadry offered unusually direct insight into how each manufacture is approaching product development, heritage, and shifting collector behaviour. That research-driven approach continued across several technical features, including his hands-on review of the Rolex Land-Dweller, the most consequential mainstream release of 2025. His analysis unpacked both the engineering decisions behind the cal. 7135 and the strategic implications of Rolex introducing a new collection. Finally his analysis of the record-breaking Patek Philippe ref. 1518 in steel and reporting from the major auctions traced the evolving tastes and appetites of a tightening pool of top...

Patek Philippe s Grand Exhibition Returns Dec 15, 2025

Patek Philippe’s Grand Exhibition Returns to Europe in Milan

Patek Philippe has just revealed details about the Watch Art Grand Exhibition Milan 2026, which is set to take place in October 2026. The event marks the seventh edition of the brand’s large-scale public exhibition series, and its return to Europe following the most recent instalments in Tokyo, Singapore, and New York. The biggest yet With a display area covering 2,540 square metres, the exhibition will be the largest Watch Art event organised by Patek Philippe to date. As with previous events in the series, the exhibit will feature immersive replicas of the brand’s Salon on Geneva’s Rue du Rhône, the manufacture at Plan-les-Ouates, and the Patek Philippe Museum, all constructed under the dome of the Palazzo delle Scintille, now known as CityOval. For a taste of what’s in store, the Patek Philipe website still hosts an immersive experience of the 2022 edition in Tokyo. The exhibition will showcase the brand’s entire current collection, alongside a dedicated Rare Handcrafts selection comprising dome clocks, pocket watches, and wristwatches, with around 500 pieces in total on display. Artisans will also be on hand to demonstrate techniques like miniature enamel painting, cloisonné enamel, hand engraving, wood marquetry, guilloché, and gem-setting. As is customary for Watch Art exhibitions, the Milan event will see the launch of several limited-edition watches across different segments of the collection. The 2023 Tokyo exhibition, for instance, included a Rare Ha...

Complicated Collectors: James Ward Packard SJX Watches
Patek Philippe had just completed movement Dec 9, 2025

Complicated Collectors: James Ward Packard

On 27 April 1927 a nurse walked into a room at the Cleveland Clinic carrying a leather case. The patient was sixty-four, a section of skull removed, the ache of radiation still working behind his eyes. On the charts he appeared as James Ward Packard, co-founder of Packard Electric and Packard Motor Car Company. To the nurse he was a difficult case. To Geneva he remained the client for whom Patek Philippe had just completed movement number 198’023, an astronomical watch that had absorbed three years of calculation and bench work. James Ward Packard. Image – Lehigh University Photograph Collection Inside the case lay a carillon minute repeater on three gongs, coupled to a full perpetual calendar with moon phase, equation of time, and sunrise and sunset indications calculated for Warren, Ohio. On the reverse, a deep blue sky disk carried five hundred and twelve gold stars, turning at sidereal speed around a small Polaris. The sky above his birthplace had been compressed into a circle of lapis and gold, moving in his hands as it moved above the town where he had been born, built factories, endowed an engineering laboratory, and which he now understood lay beyond any realistic hope of return. Consolation held little appeal for him. Packard placed his trust in precision, in the ability to describe a situation so exactly that it became bearable. The watch answered a question he had circled since childhood: if the world always exceeds your grasp, can you still know, to the min...

Hands On: F.P. Journe Tourbillon Souverain Vertical Joaillerie Rubis SJX Watches
Patek Philippe s 2022 launch Dec 9, 2025

Hands On: F.P. Journe Tourbillon Souverain Vertical Joaillerie Rubis

Earlier this year F.P. Journe unveiled its most daring jewellery watch yet, the Tourbillon Souverain Vertical Joaillerie Rubis, set with the largest baguette rubies ever used in watchmaking. Despite the current popularity of high jewellery watches, the Tourbillon Souverain Vertical Joaillerie (TVJ) Rubis is an audacious undertaking that required eight years to accumulate the right gemstones – and the destruction of 61 carats of gem-quality rubies to make this single watch. Initial thoughts Haute joaillerie watches of this sort are not new; the 1980s and 1990s saw significant demand for gem-set complicated watches, especially in Asia. But Over the last decade such watches have shifted from niche offerings to an important (and resilient) pillar of the business for many brands. Coloured stones are seeing marked interest too, as a sort of trend within a trend, as exemplified by Rolex’s “Rainbow” Daytona, one of the brand’s hottest models. Patek Philippe’s 2022 launch of the gem-set Grandmaster Chime trio can also be seen as a milestone for the genre, with one of Geneva’s flagship fine watchmaking brands adorning its flagship watch with diamonds, emeralds and sapphires. A unique Piaguet minute repeating pocket watch that’s a fine example of 1990s gem-setting high horology But with the TVJ, it’s clear that F.P. Journe is not simply following industry trends – this watch is eight years in the making and belongs to a two-decade tradition of high jewellery tour...

Patek Philippe Pocket Watches Sotheby’s upcoming Dec 6, 2025

In-Depth: The Mysterious Double-Movement Patek Philippe Pocket Watches

Sotheby’s upcoming auction in New York brings to light a pair of remarkable Patek Philippe pocket watches with double movements once owned by John Motley Morehead III (1870-1965), an American patron of the brand with exotic taste. Unknown even to Patek Philippe until now, the two watches each include a primary minute repeating base movement with a secondary movement under charismatic doré dials. Beyond their intrinsic rarity, the golden duo are significant from a historical perspective in offering a portal into early 20th-century American watch collecting, when interest began to shift from decorative to technical. The who A chemist who helped form Union Carbide, Morehead seems to have had a penchant for unusual, highly complicated watches. He also owned a triple complication with upside down “American” perpetual calendar, carillon minute repeater, and a double chronograph (as in, two separate chronographs) as well as a rattrapante but with only two seconds hands. The excellent research by Sotheby’s uncovered record of another of Morehead’s watches that was a carillon repeater with two sets of hands, like these watches, but powered by only one movement. Both double-movement watches going on the block at Sotheby’s have a primary movement with minute repeating on the back and a secondary simple movement on the front. The smaller of the two makes do with just a minute repeating base movement, while the larger watch also has a split-seconds chronograph with a minut...

Breguet Celebrates Striking Heritage with Classique Grande Sonnerie Métiers d’Art 1905 SJX Watches
Patek Philippe rather than scavenging ebauches Dec 1, 2025

Breguet Celebrates Striking Heritage with Classique Grande Sonnerie Métiers d’Art 1905

The penultimate entry in Breguet’s 250th celebration is the Classique Grande Sonnerie Métiers d’Art 1905, a complicated pocket watch that unites several of Breguet’s creations, along with the métiers d’art know-how and high-technology of the modern Breguet manufacture. The 1905 features hand engraving and flinqué enamel, as well as using Breguet’s magnetic strike governor and gold gongs. As with all of the brand’s 250th anniversary creations, the nearly 60 mm case is made of Breguet Gold, with Bleu de France for an additional pop of colour. Initial thoughts During the 2000s, Breguet launched the Montre de Poche 1907, a minute repeating tourbillon pocket clock watch with grande et petite sonnerie. At the time, several of the best brands were building new complicated pocket watches, most notably Patek Philippe, rather than scavenging ebauches. In the 20 years since, new production complicated pocket watches have disappeared from nearly every brand’s catalogue – except for Breguet’s. The Montre de poche 1907BA/12. Image – Breguet Officially the 1907 has only been offered in yellow gold – though white and rose gold examples probably exist as well. Now, to celebrate 250 years of the house of Breguet, the 1907 gets a new look and technical overhaul with the striking Classique Grande Sonnerie Métiers d’Art 1905 in an 18k “Breguet Gold” case. The 1905 is not completely novel, mechanically speaking, as none of Breguet’s launches this year have been...

Highlights: Complications on Bracelets at Christie’s Hong Kong

The uniform of high complications almost invariably includes a leather strap; a metal bracelet remains an uncommon pairing with, say, a grande sonnerie. Christie’s upcoming Hong Kong auction, however, brings an unexpected abundance of complicated watches on bracelets for collectors who prefer metal, including notable examples from Patek Philippe and A. Lange & Söhne. This season’s sale is anchored by two major private collections, most prominently the second part of The Chronicle Collection, the first half of which was dispersed earlier in the spring. The consignor began collecting in the 1990s, a fact reflected in the depth of neo-vintage highlights throughout the catalogue. Lot 2442 - Patek Philippe ref. 3448⁄8 with Possibly Unique Ruby Dial The Patek Philippe ref. 3448 was the first self-winding perpetual calendar produced in series. According to movement numbers, it is likely 586 were made in total - this lug-less example was one of the first made. Beyond its historical interest, the ref. 3448 is underpinned by one of – if not the – most beautiful automatic movements ever made: the cal. 27-460 Q. Looks aside, it was one of the most technically competent automatics of its era, with an overcoil hairspring, free-sprung balance, and bi-directional winding using a cam and pawl system. Atop this worthy base calibre, the ref. 3448 adds the iconic windows perpetual calendar by none other than Victorin Piguet. The ‘/8’ in ref. 3448/8 suffix denotes the style ...

Highlights: Complicated Patek Philippe at Christie’s Hong Kong

Christie’s Hong Kong returns this autumn with an extraordinary offering of rare and important Patek Philippe watches, headlined by a ref. 1518 in yellow gold. The auction is defined by two major private collections, most notably Part 2 of The Chronicle Collection - the successor to this spring’s successful first chapter. From neo-vintage rarities to heavyweight modern complications, the sale presents one of the of the most interesting Patek Philippe selections of the season. Lot 2225 – Patek Philippe Ref. 3979HJ Minute Repeater The story of Patek Philippe’s mastery of the modern minute repeater begins in 1989 with the launch of the ref. 3979 and the calibre R 27 PS. Launched to commemorate the brand’s 150th anniversary, the ref. 3979 was the brand’s first automatic minute repeater, and its first wristwatch to feature a silent centripetal governor, which was still novel at the time. According to the serial number, the present lot was the 47th ref. 3979 to be made, out of approximately 100 units produced over a nine year run. Further distinguishing the current lot is its classical enamel dial, which was a relatively uncommon configuration for this reference. The compact 33 mm yellow gold case is a love letter to classical dress watches. The case itself was made by Ateliers Rèunis, the brand’s own case maker, and was manufactured in the building that now houses the Patek Philippe museum. Today, more than 35 years after its launch, the cal. R 27 PS is still am...

Highlights: Pocket Watches at Phillips Hong Kong

The upcoming Phillips Hong Kong auction includes a diverse and spectacular selection of pocket watches spanning two centuries. From early 19th‑century enamel masterpieces crafted for the Chinese market to 20th‑century tourbillon chronometers that triumphed at observatory trials, the lots on offer demonstrate the technical and aesthetic evolution of the watch over the last two hundred years. Lot 1086 – S. Smith and Son No. 1899-1 Tourbillon Chronometer with Kew Class A Certificate Albert Pellaton-Favre constructed the first of two tourbillons in the auction, which was later retailed by S. Smith & Son. The other, by Patek Philippe, is the work of his son, Jämes-César Pellaton. Both are depicted in Reinhard Meis’s famous Das Tourbillon. The English and Swiss disagreed on what constitutes a chronometer. The English argued that a chronometer must use a chronometer (detent) escapement, while the Swiss considered any watch a chronometer if performed well enough – which the English would call a “Half-Chronometer”. As the Willis enamel dial boasts, the first is a chronometer by both English and Swiss reckoning, with a spring detent escapement and “Especially Good” certificate from the Kew Observatory. While S. Smith and Son retailed quite a number of tourbillons, including others with detent escapements, most were sourced locally, while the present lot uses a Swiss movement. The London branch of Baume Frères ordered six tourbillon chronometers from Albert Pella...

Patek Philippe ref 3424/1 “Gilbert Albert” Nov 11, 2025

Report: Geneva Fall Auctions 2025

The just-concluded Geneva auction season was mostly a plateau with several striking peaks and a few lows. The peaks were marked by desirable timepieces that outperformed by far, yet shared little in common with one another in terms of style or period. The peaks ranged from multiple F.P. Journe watches to a diamond-set Patek Philippe ref. 3424/1 “Gilbert Albert” to the Breguet four-minute tourbillon pocket watch from 1809 to the Instagram-ready Patek Philippe ref. 3970 in “salmon” with Breguet numerals. Despite such diverse taste, the small pool of bidders seemed to have one thing in common: they were all focused on a “trophy” watch. The Christie’s saleroom in the Four Seasons. Image – Christie’s With few exceptions, contemporary watches from mainstream brands were cold, while vintage watches were mostly lukewarm – but as always there were exceptions. An Patek Philippe ref. 570 with a black dial signed “E. Gubelin” sold for an impressive CHF419,100 including fees, or US$523,000, at Christie’s, while Phillips sold a Rolex Daytona ref. 6263 “RCO” (or “Oyster Sotto”) for an equally impressive CHF1.39 million, or US$1.73 million – close to the historical peak for the model. A vintage watch that surprised on the downside was the 1927 Rolex Oyster worn by Mercedes Gleitze when she became the first woman to swim the English Channel in 1927 – a landmark in Rolex lore. Though it sold for CHF1.39 million, or US$1.74 million, there was just one bi...

In-Depth: Patek Philippe Ref. 1518 in Stainless Steel

Many superlatives have been ascribed to what might be the most valuable watch this fall auction season – the Patek Philippe ref. 1518 in stainless steel. Headlining Phillips’ upcoming auction in Geneva, the steel ref. 1518 is paradoxically extraordinary and ordinary all at once. As the first serially-produced perpetual calendar-chronograph wristwatch, the ref. 1518 is already a landmark Patek Philippe wristwatch, one that spawned a lineage that includes the refs. 2499, 3970, and 5970. And then there’s the ref. 1518 in steel – only four are known. The steel ref. 1518 has rarity, historical importance, and an eight-figure value; but on the wrist, this “holy grail” is compact, lightweight, and monochromatic, discreetly low-key. At a diminutive 35 mm in diameter, the ref. 1518 is small by today’s standards. The watch doesn’t look like much on the wrist from across a room; in fact, it isn’t immediately obvious to a layperson (or even a casual watch enthusiast) that the watch is worth more than most houses and vintage Ferraris. Yet the ref. 1518 in steel is appealing for many intellectual reasons: extreme rarity, historical lineage of the perpetual calendar chronograph, even sheer value. This is a trophy in many senses. Historically, the ref. 1518 was important even in its time. It was once Patek Philippe’s most complicated regular production wristwatch, and the steel ref. 1518 was likely the most expensive steel Patek Philippe when it was in the catalogue. ...

In His Own Words: François-Paul Journe on the Clock That Started It All

Exactly one auction season ago, the Breguet Sympathique no. 1 made by François-Paul Journe became the most expensive timepiece sold in 2025, though the upcoming sales include other F.P. Journe creations that might give the Sympathique a run for its money. Inspired by Abraham-Louis Breguet’s greatest invention, the Sympathique no. 1 sold in May 2025 at Phillips in Geneva for CHF5.51 million including fees, at the time equivalent to US$6.61 million, to none other than François-Paul Journe. The price was just shy of the US$6.8 million that the Duc d’Orleans Sympathique sold for in 2012 – the buyer of that was the Patek Philippe Museum. François-Paul was determined to have Breguet Sympathique no. 1 for his upcoming F.P. Journe museum that is slated to open in 2026. Despite bearing another name on the dial, the clock will take pride of place in the museum, underlining its importance to the history of F.P. Journe. The tale of F.P. Journe as a brand is naturally inseparable from the eponymous watchmaker. Like his inspiration, Abraham-Louis Breguet, François-Paul Journe is more than a watchmaker, he is an entrepreneur who has built a brand, a legacy, and more than likely, a place in history. From the very beginning, decades ago as a young watchmaker in Paris, François-Paul Journe already possessed the vision that has now come to pass. Inextricably intertwined with that vision and the story of François-Paul Journe is Breguet Sympathique no. 1, for its origins encapsulat...

In-Depth: J. Player & Son Supercomplication - All 77 mm of It

Phillips’s upcoming sale in Geneva has the most attention-grabbing roster of the Geneva auctions, including the return of a record-setting Patek Philippe ref. 1518 in steel. Yet it was the J. Player & Son No. 11’901 that most affected me. Dubbed the “hyper” complication by Phillips, the watch belongs to a rarified group of swan-song supercomplications that memorialise the final days of English fine watchmaking. Despite being over a century old, the watch easily holds its own against the fine watchmaking of today, both in decoration and mechanics. By the turn of the century, the traditional watchmaking centers of England and France were besieged by vertically integrated American super-factories from the West, and cheap but skilful Swiss labour from the East, both of which benefited greatly from mechanisation. During the waning years of English fine watchmaking, the most prestigious firms responded by attempting to move even further upmarket with highly complicated watches, and the firms remained confident in the appeal of their products. “If they are more expensive, as they must necessarily be, they last the purchaser a lifetime,” said a representative of Nicole, Nielsen & Co., the company that built this watch, said of English watches in 1912, “The better classes, indeed, have always bought, and will always buy, English-made watches, and will not buy any others”. Swiss prelude This watch started life in Switzerland as ebauche number 7’321, according to Fr...

Patek Philippe Star Caliber 2000 Under the Hammer at Sotheby’s Abu Dhabi

The Patek Philippe Star Caliber 2000 stands as one of the most technically ambitious pocket watches of the modern era. Launched to mark the turn of the millennium, it was the fourth most complicated watch in the world at its debut, but its true significance lies not in numbers, but in the ingenuity of its mechanisms, which redefined how grand complications could be conceived, engineered, and executed. An original complete set of four Star Caliber 2000 watches is being offered for sale by Sotheby’s at its first-ever watch auction in Abu Dhabi, which takes place in December. The first complete set to ever appear publicly, the sale will likely draw significant attention from collectors and institutions alike. The technical significance of the Star Caliber 2000 The Star Caliber 2000 was and is a remarkable achievement in watchmaking, but it was never the world’s most complicated watch. When it debuted, the Star Caliber 2000 ranked fourth in the official tally of complications, behind the Patek Philippe’s own Caliber 89 and the famous Henry Graves Super Complication from 1932, as well as the lesser-known Leroy 01 from 1904. Over the past quarter century, the Star Caliber 2000 has fallen down the rankings as more complicated watches, for both the pocket and the wrist, have been developed by Vacheron Constantin and Audemars Piguet. But the Star Caliber 2000 should not be judged solely by this kind of ranking, which is largely superficial. The watch is packed with a number o...

In-Depth: The Technical Evolution of Patek Philippe

The Patek Philippe approach to watchmaking has developed through a steady accumulation of choices. Since 1839, the manufacture has refined its mechanical language through proportion, regulation, and clarity in construction. Each calibre reflects priorities shaped by experience, built for durability, and adjusted for lasting performance. Understanding the technical evolution of Patek Philippe requires attention to the principles that govern its construction: structural integrity, material stability, and a consistent focus on functional accuracy. Many manufacturers embraced modernity through visible transformation and stylistic experimentation, while Patek Philippe evolved through careful integration of innovation that served enduring mechanical aims. Its development follows a logic defined by proportion, restraint, and the pursuit of lasting technical harmony. The modern-day, expansive manufacture in Plan-les-Ouates in Geneva From Jean Adrien Philippe’s keyless winding system of the 1840s to the introduction of silicon components in the twenty-first century, progress has remained guided by internal reasoning and accumulated skill. Each movement expresses a study of mechanical relationships refined over time, where advances emerge from clarity of purpose and precision in design. The chapters that follow trace this progression through its historical sequence. Each period reflects a technical response to changing demands: the shift from pocket to wrist, the rise of automati...
