Porsche Design Releases a New Chronograph 1 Paying Tribute to 75 Years of Porsche

Sometimes, weird things happen on the watch release calendar that result in an almost mystical kind of synergy. We didn’t plan today as “racing inspired chronograph day,” but the surprise release of a new Rolex Daytona paying tribute to the 100th anniversary of Le Mans and an equally surprising new Seiko chronograph with more than a little racing and competitive timing heritage means that today is all about the many flavors of tracking elapsed time. Rounding out a trilogy of new chronographs today, we have news of the latest limited edition from Porsche Design, a special variant of the Chronograph 1 celebrating 75 years of Porsche.  As car enthusiasts are likely well aware, this year marks the 75th anniversary of the first Porsche, the 356 No. 1 roadster. In the decades since, Porsche has become not just one of the most important carmakers in the world, but one of the most recognizable brands of any type. Porsche vehicles are known all over the world, and their iconic silhouettes and designs can be easily recognized even by people who don’t count themselves as car aficionados. The new watch, according to Porsche Design, is a tribute to the culture and legacy Porsche has built.  The Chronograph 1 75 Years of Porsche Edition is very similar to the 1972 Limited Edition variant of the watch released last year, and discussed by Blake here. The differences are honestly so minute, they might only be appreciated by the most rabid Porsche Design collectors, but this is a ...

Rolex Introduces the Cosmograph Daytona “Le Mans” Ref. 126529LN SJX Watches
Rolex Introduces Jun 10, 2023

Rolex Introduces the Cosmograph Daytona “Le Mans” Ref. 126529LN

Having surprised everyone with the Perpetual 1908, “Bubbles”, and “Puzzles”, Rolex continues to do the unexpected. Launched to mark the 100th year of the 24 Hours of Le Mans, the Cosmograph Daytona ref. 126529 LN is a new model based on the latest-generation Daytona launched earlier this year. But the Daytona “Le Mans” is not merely a facelifted chronograph but contains the cal. 4132. The new movement swaps out the conventional 12-hour counter at nine for a 24-hour register in a nod to the famous endurance race that Rolex has sponsored for over two decades. But perhaps most pertinent for enthusiasts are sub-dials, which are modelled on the vintage Daytona “Paul Newman”. And while availability for the Daytona “Le Mans” will be limited, at least initially, it is a regular-production model that will be available at retailers and boutiques. Initial thoughts A new Daytona with a new movement is big news not because it’s majorly different – this is still very much a Daytona – but because Rolex rarely introduces new models outside of the annual watch fair in Switzerland. And when it does, the watch tends to be a surprise in more ways than one. The new Daytona is actually new, largely because contains a new calibre, a simple variation of the current Daytona movement, but one that is mechanically different nonetheless. The movement reflects the Rolex approach to engineering that does nothing in half measures. Even though the cal. 4132 inside the Daytona ...

Kurono Tokyo Closes Out the Calendrier I Series with the Maroon Dialed “Azuki” Anniversary Edition Worn & Wound
Kurono Tokyo Closes Out May 25, 2023

Kurono Tokyo Closes Out the Calendrier I Series with the Maroon Dialed “Azuki” Anniversary Edition

The latest from Kurono Tokyo is a new version of their Calendrier Type I, a reference that was a finalist in the 2022 GPHG awards. A triple calendar is an old school complication, so it makes sense for a brand like Kurono to experiment on this platform, with their design language so deeply rooted in Art Deco principles and mid 20th century ideas around size and style. The new Calendrier is a Kurono anniversary model, thus it will be sold as a “time limited” edition, meaning prospective owners will have specific windows during which they can make a purchase, and Kurono will fill every order placed in these windows. Kurono has also announced that this will be the final version of the Calendrier Type I, so if this is a reference you’ve been hunting, we’re approaching your last chance to snag one directly from the brand.  Kurono has dubbed this model the Anniversary Calendrier “Azuki,” a name derived from the maroon color of the dial. Azuki means “red bean” in Japanese, and in Japan is a color commonly associated with cars. Maroon was once a common standard vehicle color, so this watch is subtly auto inspired and a throwback in more ways than one.  According to the brand, achieving this particular tone of maroon was a significant challenge. To get the color right, Kurono used phosphor-bronze rather than the typical brass for the dial material, which allows them to get the proper shade of red during the finishing process. Kurono notes that phosphor-bronze is m...

Auction Watch: Charles Frodsham Double Impulse Chronometer SJX Watches

Auction Watch: Charles Frodsham Double Impulse Chronometer

Online watch auctioneers Loupe This have just listed a Charles Frodsham Double Impulse Chronometer in an online-only sale that runs from now till May 11. Barely a handful have emerged – one was sold at Phillips Perpetual in London in 2021 – but this example is the first to go under the hammer. The scarcity is of the Double Impulse Chronometer on the secondary market is simply because there are few of them in circulation. Around 50 have been made to date and with about a dozen being produced each year, the wait for an order placed now stands at about eight years. The exceptional demand for the watch is entirely justified, since the Double Impulse Chronometer is arguably the most significant English wristwatch in production today. Consigned by the original owner, this specimen is quintessential Frodsham. Numbered “010800” and delivered in September 2019, this is one of the first examples made, the 13th in fact, according to Richard Stenning, co-owner of Charles Frodsham. More notably, it is an unusual combination of a stainless steel case and white ceramic dial with double cyphers. According to Mr Stenning, this was the first of only two watches with this configuration made to date. The cyphers are an option but arguably crucial since they reference the firm’s history and add to the vintage-inspired styling of the dial. Historically found on Frodsham pocket watches – often engraved on the movement but sometimes on the dial – such cyphers indicated Royal Warrant...

A Week In Watches Ep. 44: The New Releases You (Probably) Missed

Welcome to episode 44 of A Week In Watches, a week where we recover from the hustle bustle of Watches & Wonders, and ponder some of the releases that may have slipped through the cracks. We talk about a new world timer watch from Ming, a few new watches from Frederique Constant, more hits from Chopard, and even a new LM Perpetual variant in steel from MB&F; (more from the M.A.D. House coming soon!). Stay tuned as we get our hands on many of these new release for more in-depth reviews.

Do we want more of these special edition MoonSwatches? Let us know in the comments or head over to YouTube to join the discussion. In total this may have been a somewhat low key year for Watches & Wonders, but there was still plenty to explore and discover, even on the fringes and outside of the show itself. We’ve got an inside look at a few other shows taking place in Geneva last week, so keep an eye out for more from the likes of Sinn, DeBethune, F.P. Journe, Doxa, and others.

Rolex Reveals New Formal Collection With 1908

Among the bevy of new Rolex watches released this year were a few unexpected watches, which isn’t a phrase we often mutter about the brand. We saw some unusually colorful dials (more on those later), and the launch of an entirely new formal collection called the Perpetual 1908, a reference to the brand’s name coinage by Wans Wilsdorf. With its introduction, the existing Cellini line has come to a close. The 1908 lives within the ‘classic’ range alongside the likes of the Oyster Perpetual and Sky-Dweller, but feels distinctly different from any existing line. Coming from a brand that’s been at the center of the sport watch craze over the past decade, the 1908 feels like a breath of fresh air. The Perpetual 1908 is a three hand time only watch offered only in 18k white or yellow gold. The trim case measures 39mm in diameter with a divided, partially fluted bezel framing the austere dial. Within resides the Rolex automatic caliber 7140, which gets a healthy amount of decoration worthy of being presented through an exhibition caseback. This is a new move from Rolex this year, appearing on both this watch, and the 60th anniversary platinum Daytona. The bridges of the 7140 receive a finish that the brand is calling “Rolex Côtes de Genève”, a re-interpretation of the classic technique seen often in Swiss movements. It differs from traditional Côtes de Genève in that it places a narrow polished groove between each of the parallel bands. Being a Rolex, there’s a...

The Intrigue & Significance of the Patek Philippe Owned by the Last Emperor of China SJX Watches

The Intrigue & Significance of the Patek Philippe Owned by the Last Emperor of China

A historically important Patek Philippe Calatrava ref. 96 with full calendar and moon phase will soon be offered at Phillips, but the news isn’t so much about the watch itself but the story behind it. While extraordinarily rare in itself, the ref. 96 quantieme lune is exceptional for its provenance: its original owner was Aisin-Gioro Puyi, the last emperor of China and heir to a 4,000-year old imperial throne. As the final ruler of the Qing Dynasty, Puyi was arguably a hapless individual overcome by circumstances and overtaken by history – a life dramatised in the Bernardo Bertolucci’s film The Last Emperor – leaving him with a mixed reputation and legacy. The ref. 96, however, makes clear his appreciation of mechanical timepieces. Yet this long-lost imperial watch is extremely flawed on its face. But the heavily-aged dial, seemingly severely damaged, also echoes the tale of Puyi’s brief reign, a turbulent time when an empire met its end and a feudal dynasty was transformed into a modern nation. Image – PaddleWaves An Emperor’s timekeeper Ascending the throne at age two in 1908, Puyi was destined for a life of absolute power. But shortly after, the child Emperor witnessed the collapse of Imperial China and his family’s four century-old dynasty in the wake of the Xinhai Revolution of 1911 that gave birth to the Republic of China. In 1932, perhaps unwitting or naive, he became the titular ruler of Manchukuo, the puppet state of Manchuria that was controlle...

Grand Seiko’s First Limited Editions of 2023 Celebrate the 25th Anniversary of the 9S Caliber

It’s an often repeated mantra around here: every year is an anniversary year. And if a watch brand is going to be successful in today’s hyper competitive market where, frankly, a lot of brands are offering products that are remarkably similar to one another, they need to differentiate themselves. And looking at a calendar, and figuring out how many years it’s been since “X” accomplishment or “Y” watch was first released is (usually) a decent runway for explaining what makes you special. To that end, Grand Seiko is embarking on what will apparently be a year of celebrating the 25th anniversary of the Caliber 9S, a movement which has become foundational to Grand Seiko in the decades since its debut.  The Caliber 9S has become a broad family of movements over the years, as Grand Seiko has continuously refined the caliber, including adding GMT functionality. Grand Seiko has used the 9S movements as a platform for their MEMS engineering techniques, which allow for insanely tight tolerances in movement making for certain key components, and you could probably argue that 9S movements represent the most traditional watchmaking currently practiced by the brand. Today, 9S movements are universally known to be reliable and rock solid high frequency calibers that often perform even better than the specs would indicate. Most recently, the 9S served as the springboard for the creation of Grand Seiko’s next generation Hi-Beat movement, the 9SA5.  While it might not be t...

Panerai Introduces the Luminor BiTempo PAM01360 and PAM01361 SJX Watches

Panerai Introduces the Luminor BiTempo PAM01360 and PAM01361

Traditionally all about vintage-inspired, “Marina Militare” dive watches, Panerai has recently been rolling out complications with a minimalist, contemporary execution, such as the recent Luminor pepertual calendar. Sharing a similar aesthetic perhaps more practical – and certainly more affordable – is the new Luminor BiTempo PAM 1360 and PAM 1361, a GMT wristwatch with striking baby-blue accents on a blue or black dial. The PAM 1361 with a radially-brushed blue dial Initial thoughts Given its large diameter and clean dial, the Luminor accommodates complications well while still maintaining its characteristic minimalist style – if the additions are integrated properly. Panerai managed that with the BiTempo, which manages to incorporate a date, second time zone, and power reserve indicator without hindering the recognisable Panerai aesthetic. In fact, the BiTempo could pass for a time-only Luminor from across a room. That said, the second time zone isn’t a new complication for the brand – the movement is an existing calibre – so the novelty is mainly in the facelift that changes dial details like the enlarged date display and blue accents. While I appreciate that the baby blue indicators are legible, I find the colour overly pastel for the low-key, military-inspired styling. Legible both day and night Twin time zones The BiTempo has a 44 mm Luminor 1950 case with its trademark crown guard. The “sandwich” dial has the signature Luminor layout with ov...

Rolex Explorer Guide

The Rolex Explorer is in many ways the quintessential dressy tool watch from Rolex’s Oyster Perpetual collection - less flashy than the GMT-Master, less bulky than the Submariner, while still rooted, like those two models, in a history of adventure and discovery. While it has changed very little since the 1950s, today’s Rolex Explorer is the culmination of many decades of aesthetic and technical evolution, guided by a watchmaker for whom the subtlest details make all the difference in the world to its avid legions of fans. Underpinning the Explorer: Oyster Case and Perpetual Caliber The Rolex Explorer, like all Oyster Perpetual timepieces in Rolex’s Professional collection, is an expression of two technical milestones that Rolex and its visionary founder Hans Wisdorf contributed to watchmaking history. The first is the so-called Oyster case, developed in 1926, which revolutionized the construction of watch cases with its dustproof, waterproof, hermetically sealed structure, secured by a threaded caseback and a crown that screwed tightly into the case. In 1931, Rolex made history again with the creation of its first “Perpetual” movement (below), whose self-winding mechanism was driven by an oscillating rotor. The marriage of these two inventions gave rise to the “Oyster Perpetual” line of timepieces that remain at the heart of Rolex’s collection today, beginning with the Datejust in 1945 and coming to full fruition with the tool-oriented, yet still luxuri...

In-Depth: MB&F; LM Sequential EVO SJX Watches

In-Depth: MB&F; LM Sequential EVO

MB&F; has just rolled out its very first chronograph, which becomes the second model in its EVO line of sports watches that began with the LM Perpetual EVO, now the brand’s bestselling watch. Christened the Legacy Machine Sequential EVO, the new chronograph continues with the same aesthetic of an open dial that reveals the mechanics along with a streamlined case. The LM Sequential EVO is most interesting for its movement, which is paradoxically complicated yet simple. Developed by Stephen McDonnell, a constructor who’s been a longtime collaborator with MB&F;, the movement is a double chronograph capable of recording twin times simultaneously along with a “Twinverter” mechanism that can either operate both chronographs or invert them – a complicated endeavour. But the setup is a simple one, essentially two discrete chronograph mechanisms that operate independently but linked by the inverter mechanism. Initial thoughts I was impressed by the LM Sequential EVO when I first saw the watch. It is a big, imposing watch with sleek lines and a wide face that is filled to the edges with intricate mechanics and quadruple sub-dials packed tightly together. Despite its size, the watch wears well due to the shape and length of the lugs, while looking like a grand complication on the wrist. And once I understood that it was a double chronograph, I was even more impressed; it looks even more complicated than the top contenders in the category, namely the Lange Triple Split and Au...
