Cartier Tank Louis Review Teddy Baldassarre
Cartier May 28, 2025

Cartier Tank Louis Review

The Cartier Tank is one of the most thoroughly and exhaustively discussed watches of all time. At one point or another, the Cartier Tank has been worn by JFK, Princess Diana, Ralph Lauren, Michelle Obama, Muhammad Ali, Andy Warhol… the list really goes on and on. The first Cartier Tank was a prototype worn by none other than U.S. General "Black Jack" Pershing, who was the commander of the Allied forces in World War I. And while the collection was formally debuted with the Tank Normale, it would be the Cartier Tank Louis that would go on to be synonymous with the iconic rectangular-cased watch. Of course, there is so much history and lore to get lost in with the Tank and our own resident expert, Mark Bernardo, did a complete job of it, which you can read here. The Cartier Tank Louis is an Art Deco classic that has inspired countless imitators but, as with all great things, there is the real thing and then there’s everything else.  Cartier Tank Louis Case  The contemporary Cartier Tank Louis comes in a few different sizes, starting with the mini quartz which is 16.5mm wide, 6.2mm thick, and 24mm tall; to the small mechanical, which is 22mm wide, 6.8mm thick, and 29.5mm tall; to the size I will be reviewing here, which is the large manual-winding model, which is 25.5mm wide, 6.6mm thick, and 33.7mm tall. There is also the automatic Tank Louis that was introduced at this year’s edition of Watches & Wonders, which is 27.7mm wide, 8.18mm thick, and 38.1mm tall. When mos...

Hands-on – A Personal Take on the Tudor Black Bay Pro Polar, From a Fan of the Explorer II

Here, at MONOCHROME, we write about watches. That’s our job. However, before that became what we do on a daily basis, we all shared a sheer passion for watches, with, of course, our personal preferences. Our founder, Frank, is well known to be a fan of independent watchmakers and monochromatic watches (obviously…) I, for instance, […]

Interview – Andreas Wyss, CEO of the COSC, on the Need to Adapt and a “Super-COSC” Certification to Come

If you own mechanical Swiss watches, one of them potentially came to you with a COSC chronometer certificate. But not everyone knows exactly what this certificate means. The COSC is the Contrôle Officiel Suisse des Chronomètres or the Official Swiss Chronometer Testing Institute. COSC certifies Swiss-made movements or watches as chronometers (not to be confused […]

The Greatest Collectors of All Time: Courtenay Adrian Ilbert – A Passionate and Meticulous Collector with an Extraordinary Dedication to Horology Worn & Wound

The Greatest Collectors of All Time: Courtenay Adrian Ilbert – A Passionate and Meticulous Collector with an Extraordinary Dedication to Horology

“The Greatest Collectors of All Time” is a series of features that will look at what drives a collector to collect and how they go about seeking out items they want for their collections. Here we look back through time to highlight the greatest horological collectors and showcase their particular area and passion for collecting. Courtenay Adrian Ilbert (1888–1956) was one of the most notable horological collectors of all time. He had the wealth, passion and enthusiasm that enabled him to amass an immense and varied collection. This was at a formative time when many unrecognized horological gems were coming to the market due to a developing appreciation of technical horology and world circumstances. His collection, known as the Ilbert Collection, included an impressive array of timepieces from the 16th century to his time, featuring some of the rarest and most exquisite watches, clocks, and horological instruments. Professionally, Ilbert was an engineer, and his technical knowledge informed his horological expertise. His engineering insights helped him appreciate the intricate workings of the timepieces he collected and restored. He was an extremely fine craftsman taking infinite patience in the matter of restoration and repair. Courtenay Adrian Ilbert (1888–1956) Born in Reading, Berkshire during the Victorian era, on the 22nd April 1888, his family background provided him with the stability and resources to pursue an excellent education. From a young age, Ilbert ...

Hands-on – The Arnold & Son Constant Force Tourbillon 11, a Tribute to Some of the Greatest Watchmakers

In haute horlogerie, few relationships have shaped timekeeping history quite like that of John Arnold and Abraham-Louis Breguet. Bound by shared respect and a deep commitment to mechanical innovation, their friendship helped lay the groundwork for modern precision watchmaking. Arnold & Son’s latest release, the Constant Force Tourbillon 11, is a tribute to that legacy […]

A Second Look at this Year’s New Rolex Novelties Worn & Wound
Rolex Novelties Editor’s Note Earlier May 23, 2025

A Second Look at this Year’s New Rolex Novelties

Editor’s Note: Earlier this week, Rolex held an event in New York City to showcase their latest 2025 releases. We saw most of these watches in Geneva at Watches & Wonders a few months ago, but this was the first time going hands-on with the latest from Rolex for Devin Pennypacker and Garrett Jones. These are their reactions and impressions, as well as a whole bunch of photos (with natural light!) from Garrett.  Devin Pennypacker: There is a saying that gets murmured around the start of Watches and Wonders: The show goes as Rolex goes. This year, however, I was left with a feeling that Rolex was chasing trends rather than setting them for the first time in a long while. New announcements saw them leaning into pastel colors, stone dials, and even integrated bracelets to highlight their 2025 collection. To put it mildly, I was disappointed that there wasn’t immediately a model that stuck out to me as a winner of the bunch. That being said, I also didn’t have the opportunity to go hands-on with the new collection, so every thought was mere speculation. During a recent event in New York, I had the chance to spend some time with many of the new releases, form genuine opinions, and model the watches for our photography by Garrett Jones. Afterwards, Garret and I sat down to discuss a few releases we had time with, delivering our thoughts and feelings towards some of the collection, which we will have staggered below. As always, please leave your takes on these new releases ...

Since then, I’ve been watching for them, and although it’s a challenging price point for a luxury watch, I’ve come up with a few contenders that offer real value for the money.

Hands On: MB&F; SP One SJX Watches
Bulgari May 20, 2025

Hands On: MB&F; SP One

With its fifth new model in as many months, MB&F; has been on quite the run to kick off its third decade. Fresh off the launch of the fun and affordable M.A.D.2, which followed closely on the heels of a collaboration with Bulgari and the introduction of the the Legacy Machine Longhorn editions, the brand has returned with the SP One, a contemporary take on the open-worked dress watch. Sleeker than the typical Horological Machine yet more avant garde than a Legacy Machine, the pebble-like SP One is the first model in a new “Special Projects” collection that packages the brand’s signature contemporary aesthetic in a smaller more wearable 38 mm footprint. The SP One joins the collection as a regular production model in either platinum or 18k rose gold. Initial thoughts Picking up the SP One for the first time, one is struck by the light and airy nature of the watch. On the wrist, the minimalist case almost disappears, making the the SP One something of a wrist-worn display case for the Y-shaped movement. This effect is accentuated with a brushed internal flange dubbed ‘the amphitheater’ that focuses attention on the spectacularly three-dimensional mechanical architecture. The smooth pebble-like case measures 38 mm and is just 12 mm thick, making it the most compact MB&F; watch to-date. The front and rear sapphire crystals are cambered to blend seamlessly with the case, giving the SP One the feel of a polished stone. Visually, the smoothness is emphasised by lugs that ...

One of the top lots in the sale is the Rolex Oyster ref. 6100 with a cloisonné enamel dial that is only now reemerging publicly after having last been sold in 1990 Concurrently, watches from The Legacy Collection, including rare watches from Richard Mille and gem-set Patek Philippe complications, will be on show from May 22 to 28 (though that are not part of the auction).

L’Epée 1839’s Surprising Imperial Hot Air Balloon Desk Clock SJX Watches
Louis Vuitton tapped L’Epée 1839 May 19, 2025

L’Epée 1839’s Surprising Imperial Hot Air Balloon Desk Clock

Swiss clock maker L’Epée 1839’s latest desk-bound timekeeper is the Imperial Hot Air Balloon, a unique piece that is uncharacteristically classical compared to the brand’s recent launches that have tended towards modernity. It’s essentially a highly decorated, elaborately styled variant of the no-frills Hot Air Balloon clock of 2018. L’Epée 1839 was absorbed into LVMH last year, and this shift towards more traditional clocks chimes with the luxury group’s focus on higher-end and artisanal watchmaking. Notably, Louis Vuitton tapped L’Epée 1839 for its own hot air ballon-shaped desk clock. Initial thoughts While most of L’Epée’s creations are undoubtedly interesting, blending sculptural mechanics with proprietary clock movements, the clockmaker was historically a maker of classically traditional mantlepiece clocks. Most of its creations from earlier decades were styled after carriage clock. While entirely sculptural in form, the Hot Air Balloon manages to look as it belongs to a bygone era of watchmaking. A métiers d’art creation, the unique piece is restrained and ornate, while being modern only in the way it displays the time. Otherwise, the miniature flying object would sit comfortably in a historical residence. Not to say that other L’Epée are not well executed, but their modern and structural constructions don’t usually allow for classic artisanal crafts to be put to good use. The Hot Air Ballon’s centrepiece is the blue enamelled surface...

Report: Geneva Spring Auctions 2025 SJX Watches
Richard Mille RM UP-01 Ferrari May 14, 2025

Report: Geneva Spring Auctions 2025

Despite everything, including tariffs and a strong Swiss franc, the Geneva auction season turned out to be a strong one, with some of the strongest results being in the most surprising segments. The bigger winner this season was Phillips, which sold a bit under 200 lots for CHF43.4 million including fees, while also claiming the most valuable lots for the season, reflecting Phillips’ strong leadership and team. Despite being the market leader by some margin, the Phillips catalogue was arguably the riskiest as it included several high-value pocket watches and clocks – timepieces that not part of mainstream collecting today. Yet the gamble paid off with the most valuable timepiece this season being its Breguet Sympathique no. 1 that sold for CHF5.51 million. Christie’s achieved CHF21.2 million with a similar number of lots that were arguably more conventional in taste and format than at Phillips. One of its most valuable lots was a Cartier Crash “NSO” with a special order dial that sold for CHF736,000 – one of the biggest surprises of the season but proof that being eye-catching enough for social media is a big factor in desirability and value today. Interestingly, the Crash sold for exactly the same as the Richard Mille RM UP-01 Ferrari. The Crash went for about 15 times the original retail, while the RM UP-01 was about half of retail. The Crash NSO “nickele” grey. Image – Christie’s Over at Antiquorum, the tally was CHF10 million – from almost 800 lot...

“Patina” or Damage? Scrutinizing the Fine Line Between Pleasing and Pesky Imperfections Worn & Wound

“Patina” or Damage? Scrutinizing the Fine Line Between Pleasing and Pesky Imperfections

The Ship of Theseus paradox involves the legendary vessel that Theseus––a Greek mythological hero who rescued the children of Athens and slayed the Minotaur of Crete––traveled on. To honor his valiant efforts, the Athenians preserved the ship and, over time, swapped parts that decayed or had become damaged, eventually replacing all of its original components. This, in turn, begs the question: is it still Theseus’ ship even if all the parts have been replaced? If not, at what point did it cease to be the original?  Now that our history lecture is over, I want to utilize this idea of time and identity to talk about a topic near and dear to our watch-collecting hearts: patina. A number of journalists and enthusiasts have discussed what patina is, how it can be defined in a horological sense, and the many forms it can take, but no one (to my knowledge) has discussed when deterioration or damage becomes patina. This may seem like a rather abstract subject to discuss, but most, if not all, collectors take condition into consideration when shopping for a watch. The two main questions that will help get to the bottom of this patina paradox are: 1.) At what point does damage become patina? and 2.) Is patina just a buzzword to market a watch with lots of aesthetic flaws?  The Evolution of Flaws to Patina One of patina’s most essential characteristics is its dependability on age. The natural degradation of luminous material, the color-changing properties of a dial often...

Zenith Defy Skyline Review Teddy Baldassarre
Zenith May 13, 2025

Zenith Defy Skyline Review

While the El Primero movement architecture may serve as the face of the Zenith brand, it is the Defy collection that remains its soul. The Defy represents an historically significant ethos for Zenith, a creative foundation that is just as important to the Swiss brand’s past as it is to its future. Originally meant to be a showcase of innovation and ideas, the Defy collection serves dual purposes: to preserve and celebrate innovations of the past in the “Revival” subfamily, and to continue innovating for the future in the series’ other branches. In 2022, the brand took a big step toward the future of the collection with the release of the Zenith Defy Skyline, a watch that simultaneously looked to build on successful elements of the past and also to capitalize on the integrated-bracelet sport watch trend that had taken hold of the industry. The Zenith Defy collection has roots in the 1960s and ‘70s, when many of the brand’s most iconic and exciting references were released (you can read a more in-depth history here). Many of these have been reborn in the form of modern Revival references, allowing a new generation of enthusiasts to discover them again, or for the first time. These designs weren’t afraid to take risks, from the shape of the case, to the bracelet integration, right into the dial colors and textures. The Defy name quickly came to signify a huge amount of character, and that’s on full display within the brand’s current stable.  In finding a mo...
