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 Worn & Wound

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

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...

Orient Star’s Manual-Wind Moon Phase is Slick and Silicon SJX Watches
Grand Seiko Sep 29, 2025

Orient Star’s Manual-Wind Moon Phase is Slick and Silicon

The Orient Star M45 F8 Mechanical Moon Phase Hand Winding is the brand’s first manual-wind moon phase, and also the first in years with a solid dial, making it a refreshing change of pace from the brand’s usual fare that leans towards open-worked and occasionally over-designed styling. Initial Thoughts Excepting the vintage inspired Diver 1964, the M45 F8 moon phase is the most attractive watch in the Orient catalog to my eye. Most of the brand’s designs are too busy for my tastes, so these entries are a welcome departure that will certainly appeal to enthusiasts with more classical tastes. The moon phase disk itself, with mother-of-pearl inlay, is a highlight. And the absence of a seconds hand is a pleasant surprise, though the moon phase sub-dial feels naked without the traditional co-axial small seconds hand. Since the small seconds version of this calibre is not compatible with the moon phase module, Orient could have moved the Orient Star logo onto the sub-dial for more visual balance. Most importantly, this is a manually wound watch – with a competent movement – in a price segment where such things are hard to find. Looking at Japanese watches in particular, manual wind options from Grand Seiko and Credor are significantly more expensive, while Seiko, Orient, and Citizen dropped their entry-level manual watches years ago. Pleiades About two years ago, Orient Star reorganised its catalog by launching M Collections, a family of watches each named after astron...

From the Seiko SKX to the SPB317: How I Fell in Love with Seiko Again

At the end of summer 2014, Dad gave me my first mechanical watch. There was nothing ceremonial about it; he simply handed me the box in the car. “I’m starting a new tradition, and it’s a grown-up gift since you’re heading to college,” he said. I looked down at the box. It said Seiko. I was familiar with the brand. In fact, it was what I had been wearing up to that point: reference SNE039, a mid-sized solar-powered watch that Grandpa gave me when he saw me showing interest in it. I still have it. But this Seiko was different. It was a reference SKX173, a sibling of the beloved SKX007 dive watch that has led many a good man down the rabbit hole. It had a waterproof case, rotating dive bezel that I had no clue how to operate, and most importantly, an automatically winding movement.  “It’s easy – just shake it a bit to get it going,” said Dad. (OGs will remember the caliber 7s26’s lack of hand winding). I took the watch out of the box and shuffled it back and forth gently to coax it to life. It did, and as I stared at the sweeping seconds hand, I marveled that a microscopic team of gears, levers, and springs were all working harmoniously just to tell time. As an incoming engineering student, I couldn’t have asked for a better gift. I secured the black rubber strap on my wrist, and that was that. The remainder of the summer was spent reading everything I could get my hands on about Seiko watches and mechanical timekeeping at large. The excitement of movin...

31 Crazy Unique Watches

Generally speaking, most watch consumers tend to prefer watch designs that are - for lack of a better term - approachable, the kind of style that can be worn every day without drawing an undue amount of attention. Class is often associated with being understated, after all. For most enthusiasts, design, craftsmanship, mechanical complexity, and value for dollar are all subjectively weighed in an effort to determine the most appropriate timepiece decision. Naturally, the result is that the watch industry focuses a great deal of its effort on  practical designs intended to please a large percentage of the population in an ultimate effort to sell. Outliers and more novel designs are considered risky and are often left behind in the race for mass-market appeal. But what if, some independent watchmakers ask, you’ve simply had enough of brands cutting-and-pasting each other’s designs? We’ve all noted, “That’s more or less a Rolex Submariner,” one too many times when seeing the latest "new" piece. Let's say that sometimes you may want something different and maybe even a little bit crazy. And for the sake of argument, and for a more comprehensive list, let's also say you have a nice chunk of money to spend. Sure, you could take your cash and make an informed, reasonable decision to keep on fitting in with all the other watch nerds on your Instagram feed, but this list is for enthusiasts interested in the road less traveled, searching for different, interesti...
