Orient Updates the Bambino with a New No Date Version of the Enthusiast Favorite

The Orient Bambino is one of those watches that’s an undisputed enthusiast classic. For almost everyone currently involved in our hobby, they’ve come across the Bambino in one way or another. It’s one of the most recommended enthusiast watches for beginners because of its classic dress watch style, reliable mechanical movement, and authentic brand history and credibility. It’s a watch that immediately puts you inside of our community.  If there was an ongoing critique of the Bambino, it might be that until now it had only been available with a date complication. This flies in the face, somewhat, of traditional dress watch norms, but is a common concession that larger watch brands make for the modern, non-enthusiast consumer. After what must have been years worth of feedback from collectors, Orient has just introduced new Bambino models without a date that seem aimed squarely at the collector community.  The new Bambino 38 No Date is available in white, ivory, green and brown dial options, as well as a gray limited edition of 3,300. Dials have a pleasing symmetry thanks to the lack of a date aperture, with Roman numerals at the even numbered hours and simple baton indices elsewhere. The perimeter of the dial has a hash mark minute track in either white or black depending on the dial color.  The Bambino 38 No Date runs on the new F6524 automatic movement, which has a power reserve of 40 hours. Orient makes simple but reliable automatic movements which are notable ...

Meistersinger Introduces the Archao Worn & Wound

Meistersinger Introduces the Archao

The one handed watch is a curious thing. On the face of it, it seems illogical. On a mechanical watch, stripping away a more precise minute hand in favor of a single hour hand negates one of the things enthusiasts covet most: precision. Or, at least, the relative precision. Things like COSC certification and the hard work and ingenuity that go into making mechanical movements become secondary when you pull back sufficiently far from an ability to clock the time to the exact second (indeed, the COSC will not certify any watch without a seconds hand).  But removing that hand is additive, as well. It forces the designer of a watch to think very critically about how that hand is going to tell the time, and the thing that actually defines one handed watches is not so much the fact that they only have a single hand, but the way in which that hand interacts with any timing markers on the dial. There are different approaches, of course. Avant-garde designs might strip out markers altogether, so that a dial’s texture or material can be the singular focus of a piece. This, to me, feels like the most jewelry oriented option possible. Another approach, and the one most often favored by Meistersinger, a brand known primarily for their one handed watches, is to focus like a laser on readability at a glance, designing markers and indices that are large enough and graduated to a degree that makes it relatively easy to get the precise time at a glance. I often think about the time I spe...

Audemars Piguet’s 150 Heritage is a Universal Cultural Calendar

Audemars Piguet celebrated 150 years of existence in 2025, but its celebrations have continued into the new year with the 150 Heritage Pocket Watch. While many large ultra-complicated pocket watches are exercises in nostalgia, the 150 Heritage is a modern marvel of micro-mechanical engineering with never-before-seen functionality inside a surprisingly compact 50 mm case. Initial thoughts Few brands can match Audemars Piguet’s track record of producing Grand Complication pocket watches, but the 150 Heritage surprises by adapting a calibre originally intended for the wrist. A complicated pocket watch with a simple name, the 150 Heritage is built around the cal. 1150, a newly developed hand-wound movement that adapts the architecture of the ambitious cal. 1000 developed for the Code 11.59 Universelle, and as such it includes past RD-series innovations. That said, the differences between the Universelle and the 150 Heritage are quite significant, thanks to an intriguing new feature: a hinged mechanical calculator, isolated from the movement. The intricate system is housed inside the case back and allows the user to effortlessly cycle through dates across any year to be able to read a surprising number of culturally-relevant dates based on lunar, solar and lunisolar cycles.  The device feels a bit like a time machine, as the lucky owner can go into the past or look into the future and find out the exact dates of Catholic Easter, Ramadan, Equinoxes and many others, along with...

Industry News: Sellita Introduces the SW200-2 with 65 Hour Power Reserve

There’s a “don’t change it if it ain’t broke” mentality in Swiss watchmaking. Progress is slow, and it often seems that there’s a general distrust of change. An example of this is in the mechanical movements that power most of our watches. Chances are, you have at least one watch with an ETA 2824 or a movement based on the 2824 in your collection. If you’re like me, you have several. For Swiss-made watches of a certain price point, they are the standard. They are “workhorses” that, while not the most feature-rich, offer reliability and serviceability. And part of the reason for that is that the design has been around, largely unchanged, since the 1970s (the 2824-2, which is the current standard, was released in the 80s). That is, until 2013, when ETA launched 80-hour movements based on the 2824-2. First debuted in a Tissot as the Powermatic 80, ETA nearly doubled the 2824’s power reserve by slowing the escapement’s frequency from 28,800bph to 21,600bph, introducing synthetic components, and increasing the mainspring’s capacity. The biggest update to the 2824 format in a generation (though they no longer use that numbering), as ETA is part of Swatch, these movements gave the group’s catalog of brands under Omega an unexpected edge in the market, but were not available to third-party brands, thus limiting their overall impact. The ETA 2824 featured in a Sinn 556i In 2003, Sellita began supplying movements to third parties as a response to Swatch’s...

Best Solar-Powered Dive Watches For Every Budget

While solar-powered quartz technology has been around for decades, it’s still a relatively new innovation in the centuries-old watch world. I wouldn’t say the solar-powered revolution has fully arrived (especially as contemporary enthusiasts continue to find appeal in the craftsmanship of mechanical calibers in an increasingly digital world), but the technology has undoubtedly become more reliable and refined in recent years. The convenience and ease of being able to charge up your watch in both natural and artificial light sources, as well as the security of the long-lasting battery life, actually lend themselves well to more high-stakes and tactical situations. Riffing on that theme, I’ve scoured the watch industry for the best solar dive watches on the market.

Do Rolex Watches Tick? It's All In The Beat Teddy Baldassarre

Do Rolex Watches Tick? It's All In The Beat

“Do Rolex watches tick?”  This is, apparently, a frequent question and a common concern of newbie Rolex owners, but the premise of the question is actually driven by a misconception. Virtually all Rolex watches - in fact, all watches equipped, as most Rolexes are, with a mechanical movement - are  indeed ticking while they are running. If your ear is not perceiving it, that is only because the ticking is so rapid - nowadays, at least eight times per second - that the watch’s seconds hand appears to be moving in a smooth, sweeping motion. This can be quite noticeable if you have experienced only the much more visible, (and easily perceptible) one-tick-per-second movement common to the seconds hand of a quartz watch. In fact, if your Rolex watch is ticking once per second, it might be worth taking a moment to authenticate whether or not it is real or counterfeit. Allow us to explain. [toc-section heading="The Difference Between Mechanical and Quartz Movements"] A mechanical movement is the oldest type of movement in horology. It uses a coiled metal spring, called a mainspring, that releases energy as it uncoils through a series of gears to drive a weighted, oscillating wheel called a balance wheel. The balance wheel’s oscillations are linked to an escapement, which periodically releases the gear train to move the hands forward to record the passing of hours, minutes, and seconds. Originally, the mainspring needed to be wound periodically by hand, first by a...

Omega Co-Axial Movement Explained: A Radical Invention

What is a Co-Axial Movement? More specifically, what is the now-famous Co-Axial Escapement that has become a standard feature on most all Omega watches? In short, it's both a radical concept by one of the modern era's most revered watchmaking geniuses and the culmination of a Swiss watch brand's longtime dedication to improving watchmaking accuracy. Here is the story of Omega's co-axial movements.  [toc-section heading="Early Omega Movements"]  While it is best known these days for its signature watch models, like the Speedmaster “Moonwatch” and the James Bond-worn Seamaster, Omega has also been a pioneer in movement-making since nearly the beginning. The company was founded in 1848 by 23-year-old watchmaker Louis Brandt (with family, above) in the Swiss village of La Chaux-de-Fonds. Originally called La Genérale Watch Company, and eventually renamed Louis Brandt et Fils after Brandt’s sons joined the business, it originally produced key-wound pocket watches from parts supplied by local artisans, After the growing company moved from La Chaux-de-Fonds to the more bustling town of Bienne, in the Swiss Canton of Bern, it pioneered a series of industrial watchmaking techniques and also began making its own in-house movements. The first one, called the Labrador, launched in 1885 in a now-legendary series of pocket watches. Nearly a decade later, in 1894, came the company’s chef d’oeuvre, the 19-ligne Omega Caliber, which was notable at the time for its enviable acc...

Owner’s Perspective: Seiko 5 Sports SKX SRPL87K In The Vibrant Yellow Dial

A bright yellow Seiko that reminds you that watches are meant to be fun. They don’t all have to be technical and serious, just pure enjoyment on the wrist! This is my story with the SRPL87K. What We Love The mango-yellow dial brings instant personality and fun to any outfit. It’s an easy grab-and-go mechanical watch you never have to think twice about. The 5-link bracelet upgrade elevates the whole look far more than expected. What We Don’t The lume is good, but not as strong as some other Seiko models. 100m water resistance is fine, but 200m would’ve felt closer to classic SKX DNA. No bracelet option for the yellow dial out of the box — a missed opportunity given how good it looks on one. Overall Rating: 8.6/10 Value for money: 9/10 Wearability: 8.5/10 Design: 8.5/10 Build quality: 8.5/10 There’s something about Seiko’s SKX range that leaves an impression on you. Even if you never owned the original model, the SKX collection of modern is the entry-level diver and the perfect canvas for those who love to mod their timepieces. It is the watch that turned a lot of casual wearers into full enthusiasts! While Seiko may have closed the chapter on the original SKX line many years ago, the spirit of the collection certainly didn’t disappear. There have been many modern iterations in Seiko’s current collections that have been inspired by SKX models of the past, each carrying hints of the familiar dive watch DNA: the practicality, the simplicity, everyday toughnes...

Fears and Ace Jewelers Release a Limited Edition Paying Tribute to the De Stijl Movement

Much like art cars, art watches are often divisive; those who favor function tend to dismiss them as wrist candy, while the stylish or art-forward tend to snap them up as fast as possible. So, when a microbrand with a reputation for both mechanical and design prowess decides to make an art watch-in this case, a watch inspired by a recognizable artist-it gets everyone a little giddy, and a little nervous. Enter the newest Fears and Ace Jewelers’ collaboration: the Brunswick 38 De Stijl Edition. Put forth as a partnership between Dutch artistry (as represented by the Amsterdam-based Ace Jewelers) and British refinement (courtesy of Bristol’s own Fears), the De Stijl Edition is inspired by the Dutch artistic movement of the same name, and based on the Fears Brunswick 38 platform. The De Stijl movement was founded by Theo van Doesburg in the early twentieth-century, and its most well-known artist is Piet Mondriaan, whose work has clearly played a large role in the conception of the De Stijl Edition; more on that below.  First, though, let’s take a look at the basics of the Brunswick 38. It features a 38mm stainless steel cushion case that Fears fans will recognize instantly, thanks to now-iconic design elements like the onion-shaped crown and lack of flat surfaces. Inside, a manual-winding La Joux-Perret D100 movement provides the mechanical heartbeat of the De Stijl, and ensures the level of functionality and refinement that enthusiasts have come to expect from Fea...

The Wild Watches of German Polosin SJX Watches
Nov 14, 2025

The Wild Watches of German Polosin

The Kopf watch is the brainchild of German Polosin, a self-taught independent watchmaker who left Moscow for Bristol, England, where he runs Horological Underground. Conceived in 2016 and still in (limited) production today, the Kopf watch embodies the belief that a watch should be a form of mechanical sculpture. Its design feels more cybernetic than classical, combining an anthropomorphic ‘face’ with a hinged, jaw-like crown guard, hammered metal surfaces, and tritium-lit eyes. While the Kopf’s aesthetic recalls science-fiction icons like The Iron Giant or Futurama’s Bender, its construction reflects a deeply traditional craft ethos. In terms of style, German Polosin is far removed from the biker or heavy metal aesthetics one might expect from the creator of the Kopf watch. Initial thoughts It’s been more than six years since I first saw the Kopf while visiting German Polosin, the Russian [now English] independent watchmaker, who was still working in Moscow at the time. I was impressed that from the outset, the concept behind the Kopf watch was to express the art of metalworking. In this respect, he shares similarities with another independent watchmaker, the Finn Stepan Sarpaneva, who drew inspiration from biker subculture for his own creations. Mr. Polosin conceives watches as mechanical sculptures, with their shape and finish reflecting their functionality: “I would love to see it finished like… a Beretta or a Desert Eagle.” Kopf watch – the aesthetic...

Complicated Collectors: John Pierpont Morgan SJX Watches

Complicated Collectors: John Pierpont Morgan

As part of a continuing series on great watch collectors, following the first studies dedicated to Elliott Cabot Lee and Thomas Engel, the third instalment turns to the horological world of John Pierpont Morgan Sr. (1837-1913). Based on the famous 1912 Chiswick Press catalogue, this analysis reflects the range and typological structure of his collection. These watches span devotional and allegorical forms, astronomical instruments, and multi-functional works of mechanical synthesis. While Morgan’s approach has sometimes been described as encyclopaedic rather than selective, the collection itself tells a different story, one in which historical resonance and technical refinement consistently overlap. The selection offers a tangible expression of Morgan’s collecting logic, in which cultural meaning, mechanical ingenuity, and symbolic intent were sought in equal measure. The man In the pantheon of American capitalists, J. Pierpont Morgan occupies a singular place: titan of industry, consolidator of empires, and paradoxically, one of the greatest cultural preservationists of his age. Born in Hartford, Connecticut in 1837, the son of an ambitious transatlantic banker, he came of age amid the expanding architecture of American finance. His education, from early childhood, was European. He studied in Switzerland and later in Germany, where a brief period at the University of Göttingen introduced him to the German language and the foundations of art history. These formative ...

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...

The New Bremoir South Beach, and the Influence of Art Deco Design

Virtually every watch enthusiast is familiar with Art Deco, even if they don’t know it. Art Deco, short for Arts décoratifs, first appeared in Paris in the 1910s and spread across the globe over the following two decades. You may not be familiar with Art Deco’s principles - bold geometric forms and streamlined, mechanical aesthetics, among them - but you are almost assuredly familiar with some of its most famous designs, like the Cartier Tank and JLC Reverso. Worn & Wound contributor and Art Deco enthusiast Christoph McNeill considers Art Deco “the pinnacle of design,” and says he loves the beauty of the Machine Age design movement’s expression of curves and lines, obsession with mechanical aesthetics, and “streamline” nature. Wristwatches, which became popular about the same time Art Deco came onto the scene, was a natural medium for Art Deco design. “Because they’re little, tiny machines, right? said McNeill. “It sort of went hand-in-hand.” Vintage Art Deco watches from Christoph’s personal collection So, what does Art Deco design look like in watches?  “It means clean lines, very specific fonts,” said watch collector and seller extraordinaire Eric Wind. “I think of a lot of rectangles, squares, things like that. Less round, unless it’s round within a rectangle. A lot of black on silver. I think of that kind of high shine chrome when I think about Deco as well. More silver than gold.” Wind cites “a lot of Pateks from the 20s and ...

Girard-Perregaux’s Brand New Caliber GP4800 Finds Its Home in the Laureato Fifty

Let’s orient ourselves in the watch world five decades ago. The year is 1975, and we are in the height of the quartz crisis. Just six years prior in 1969, the watchmaking landscape forever changed with Seiko’s introduction of the first quartz timepiece, which called into question the future of mechanical timekeeping as we knew it. The era also marked the advent of the luxury sport watch, beginning with Gerald Genta’s Royal Oak for Audemars Piguet between 1970 and 1972. These two pivotal moments in horological history gave birth to an icon: the Girard-Perregaux Laureato. The first Laureato entered Girard-Perregaux’s catalog in 1975. The model was modestly sized by today’s standards and was even rather mid-sized for the era with a case measuring just 36mm (by comparison, the first Royal Oak began to set the tone for more oversized watches clocking in at 39mm, but was considered notably large and given the nickname “Jumbo”). The 1975 Laureato featured a two-tone construction, highlighting its mix of curves and geometric shapes. The design echoed Genta’s but with softer edges and a slightly more elevated look thanks to the addition of yellow gold elements combined with stainless steel. In line with the times, the model housed a quartz caliber, but not just any quartz caliber – it was COSC-certified. “The Laureato was more than just a new model for Girard-Perregaux’s catalog,” confirms Beatrice Morelli, Chief Customer Experience Officer. “It represente...

Behind the DIN 8330 Standard for Pilot’s Watches Worn & Wound
Sinn lead Oct 3, 2025

Behind the DIN 8330 Standard for Pilot’s Watches

Standards and certifications in watchmaking were primarily developed for chronometry, as well as to reassure the buyer that their watch had been thoroughly tested to a certain level of accuracy. The standards we see most often in the technical specifications are COSC, METAS, and other company or regional chronometry certifications. In modern watchmaking, other key standards like the ISO 6425 dive watch standard, which was developed in the 1990s and followed by watch companies, also come into play. These standards were largely based on various military set standards for watches; however, since each military set their own requirements, there was not one universally followed standard. The International Organization for Standardization (ISO) published specific requirements and testing procedures for a watch to be officially designated a “Diver’s watch”. While there is no ISO standard for pilot’s watches, there are specific requirements set by militaries around the world. One of the most well-known standards is from the WWII German pilot’s watch known as the “Beobachtungsuhren” or “B-Uhren.” B-Uhren pilot’s watch standards are well documented and are still followed by many watch companies to this day. In March 2012, Sinn lead an initiative in collaboration with the Faculty of Aerospace Technology at the Aachen University of Applied Sciences to create TESTAF – Technical Standard for Pilot Watches. TESTAF was developed so that a pilot’s watch meets all mod...
