Hands-On With Qian GuoBiao’s Split-Seconds Chronograph

This was the first time I had ever seen one of Qian GuoBiao’s watches in real life. I’d never seen one at watch shows, quickly behind glass, or even in a passing moment at a collector event. I’ve long admired Master Qian’s watches through my laptop screen, but this encounter with his Split-Seconds Chronograph was […] Visit Hands-On With Qian GuoBiao’s Split-Seconds Chronograph to read the full article.

Introducing – Twenty Years and Going Strong, the Ochs und Junior Settimana PVD

Simple solutions to complex problems could well be Dr Ludwig Oechslin’s overriding philosophy. Former curator of the Musée international d’horlogerie in La Chaux-de-Fonds, Oechslin studied archaeology as an undergraduate and obtained a PhD in Philosophy – with a scholarship to study theoretical physics and astronomy – and became a Swiss master watchmaker in 1983. Bringing […]

Our Favorite Complicated Watches Of 2025 Teddy Baldassarre

Our Favorite Complicated Watches Of 2025

When the editorial team here at Teddy was tasked with picking some of our favorite complicated watches of 2025, there was an important distinction that had to be drawn. Of course, this was the fine line between our favorite watches that absolutely nail or master a specific complication rather than just the“most complicated” watches or watches with the most complications. This year we saw one of the best world timers for the money, a novel take on the moon-phase, and Audemars Piguet’s final Research & Development watch. So without further ado, here are our picks for our favorite complicated watches of 2025. [toc-section heading="Hamilton Khaki Field Automatic Power Reserve 40mm"] Sometimes we overlook the power reserve indicator as a complication in a watch - but indeed it is and Hamilton outfitted one of its most popular watches with a power reserve indicator on the dial thus setting the new Khaki Field Power Reserve to take its place among our favorite complicates watches of 2025. You will recognize this watch for bearing so many of the hallmarks of the Khaki Field Mechanical but with the added gas-tank indicator style gauge at the nine o’clock portion of the dial. It’s 40mm in diameter and a touch under 12mm in case height and boasts a new movement under the hood by way of the H23 manual winding caliber with 80 hours of power reserve and a slipping spring that allows for winding to exceed the manual maximum in a “quirk” that also serves to aid the watch...

Hands On: Chopard L.U.C. Grand Strike SJX Watches
Chopard L.U.C Grand Strike Dec 11, 2025

Hands On: Chopard L.U.C. Grand Strike

The 30th anniversary of the Chopard L.U.C. manufacture was one anniversary among many this year, but it will likely be remembered thanks to the Grand Strike, the most complicated watch in Chopard’s history and its first grande sonnerie. Building on the successful Full Strike minute repeater architecture and making full use of the brand’s patented sapphire gongs, the Grand Strike is a chronometer-certified two-train clock watch with a push-button minute repeater. In this context, the presence of the tourbillon is almost a footnote. Initial thoughts I can count on one hand the number of brands that have created their own grande sonnerie wristwatch. It’s one of the few things in watchmaking that’s proven challenging enough to still be rare, even in the days of computer-aided design (CAD) and advanced manufacturing technology like wire erosion. For this reason, the grande sonnerie has a towering cultural presence among watchmakers and collectors, looming above all other complications. For Chopard, the Grand Strike represents the culmination of 30 years of the L.U.C. manufacture, the brand’s haute horlogerie division. The first impression of the Grand Strike is one of extraordinary depth. There’s not much of a dial, save for the minutes scale etched on the inside of the sapphire crystal, and the small concentric sub-dials for the dual power reserve displays. This depth shrinks the watch visually, and it feels dense and compact despite its rather large 43 mm size and...

Down to the Wire: De Bethune’s In-House Hairsprings SJX Watches
De Bethune s In-House Hairsprings De Dec 10, 2025

Down to the Wire: De Bethune’s In-House Hairsprings

De Bethune plans to bring hairspring production in house, aiming to become one of the very few firms able to process alloy wire into a finished balance hairspring. This requires De Bethune’s new hairspring workshop to master wire drawing, rolling, cutting, heat treatment, and assembly. The rationale? “Externally produced hairsprings meet standards based on averages that do not enable fine adjustment of the dimensions to suit a particular balance wheel or its specific positioning in a calibre,” according to De Bethune. De Bethune’s “flat end curve” mated to a hairspring sourced from a supplier. Initial thoughts As De Bethune explains it, making its own hairsprings will allow the brand to tailor its hairspring to a specific balance or movement. Since its founding in 2002, De Bethune has presented itself as being on the cutting edge of chronometry, debuting a new balance design every year from 2004 to 2010. The brand was also quick to embrace silicon, and even briefly attempted a kilohertz magnetic oscillator system, Résonique. A new year, a new balance. Sometimes two new balances. Given De Bethune’s focus on chronometry, making its own hairsprings seems like a natural next step. However, there is a reason so few brands make their own hairsprings: the process is a difficult and demanding one that benefits greatly from economies of scale. For example, H. Moser & Cie. makes less than 4,000 watches per year, however, its sister company Precision Engineering claims...

In-Depth: Breguet’s Constant-Force Magnetic Escapement SJX Watches
Breguet s Constant-Force Magnetic Escapement Dec 4, 2025

In-Depth: Breguet’s Constant-Force Magnetic Escapement

Earlier this week, Breguet rounded off its grandiose 250th anniversary with the unexpected launch of the Expérimentale 1 chronometer in Paris. Showcasing modern Breguet’s most impressive innovation to date - a magnetic constant-force escapement - the watch left many scratching their heads simply because the novel invention defies easy explanation. Here we explain the actual functioning of this remarkable invention, and why it represents such a significant step forward in terms of chronometry and escapement technology. The origins of the concept Before turning to the decidedly modern and futuristic Expérimentale 1, we must first take a short trip to the past and consider how the idea of using magnets in mechanical escapements first came to life. For that we must turn to the late 1930s, when Cecil Frank Clifford, Fellow of the British Horological Institute (BHI), started experimenting with oscillators maintained by magnetic rails or escape wheels.  He was granted a British patent in 1954 for a variety of magnetised escape wheels paired with elastic vibrating magnetic blades. The device would operate silently and Clifford envisioned it being used for naval underwater torpedoes, so the lack of ticking would be harder to pick up by sonars.  Iterations of Clifford magnetic escapements. His designs were rudimentary. The principle was that the escape wheel would be braked by a vibrating pair of magnetised blades (in several possible configurations), while simultaneously ...

Rolex 1908 Review: The Dress Watch For A New Generation Teddy Baldassarre

Rolex 1908 Review: The Dress Watch For A New Generation

It’s easy to see Rolex exclusively as a sport watch brand, if even a luxury oriented one, thanks to collections that have helped to define their respective genres, such as the Submariner, the GMT-Master, the Explorer, and the Daytona. While they undoubtedly are just that, Rolex has another dimension to be discovered in more formal territory, and it’s a side we probably don’t see as often as we should, at least if their latest 1908 collection is anything to go by. Following the discontinuation of the Cellini collection in 2023, Rolex revealed its replacement in the 1908, sporting a familiar yet novel design language, and an entirely new movement in the caliber 7140. It was an immediate breath of fresh air, and a rare truly new release from the brand.  [toc-section heading="Some Rolex Design History"] Rolex has more than a century’s worth of design language to draw upon, and it would do exactly that with the design of the 1908. From the shape of the case, to the details of the bezel, and even the design of the hour numerals, the 1908 feels like a love letter to the history of Rolex. As a result, it’s a design that doesn’t feel entirely formal in nature, landing in a more versatile space than you might imagine, especially in the right spec. This is a watch that feels appropriate in a wide range of uses, from dressed to the nines in a suit and tie, all the way down to t-shirt and jeans affairs, this is a truly dynamic platform.  From the first oyster style cases ...

Breguet’s Magnificent Magnetic Expérimentale 1 SJX Watches
Breguet s Magnificent Magnetic Expérimentale Dec 1, 2025

Breguet’s Magnificent Magnetic Expérimentale 1

Breguet concludes its 250th anniversary with the brand’s most forward-thinking watch, the Expérimentale 1 that boasts a magnetic, true constant force escapement. Equipped with a frictionless escape wheel and pallet lever driven by magnetic forces, the movement runs at 72,000 beats per hour, or 10 Hz – arguably making the Expérimentale 1 the ultimate Breguet chronometer. Impressively innovative with its use of silicon, magnets, and clever teeth geometry, the limited edition watch also marks the start of the Expérimentale line, a collection that will serve as a platform to debut new complications, technology, and designs. Initial thoughts While some might have been expecting an updated Sympathique, Breguet instead surprised with perhaps the most advanced wrist-borne mechanical chronometer in modern watchmaking. Taking cues from Abraham-Louis Breguet’s own “constant force” escapements, Breguet today harnessed the power of permanent magnets and unique teeth geometry to built a genuinely friction-less, constant torque escapement. In fact, the new escapement appears to be the only truly frictionless and constant force escapement on the market today.  Magnets have been employed in escapements in the past, but this approach was historically unreliable. Breguet appears to have discovered the right formula for a magnetic escapement. Several functioning prototypes were on show at the launch event. Moreover, Breguet chief executive Gregory Kissling explained that the ma...

Slimmer, Sharper Seamaster: Omega Updates the Planet Ocean SJX Watches

Slimmer, Sharper Seamaster: Omega Updates the Planet Ocean

Omega marks the 20th anniversary of the Seamaster Planet Ocean with a full redesign, introducing a sharper, faceted case and a slimmer profile that addresses long-standing concerns about about the model’s thickness. The fourth generation design retains the headline 600 m water resistance and METAS-certified movement, but adopts a more contemporary silhouette that differentiates it from earlier generations. The anniversary launch spans three colourways - black, blue, and the signature orange - with the latter now priced in line with the Rolex Submariner. While the refresh enhances everyday wearability, it also moves the Planet Ocean slightly away from the recognisable aesthetic that has defined the collection since its 2005 debut. Initial thoughts The Seamaster Planet Ocean is a watch that carries a lot of nostalgia for me personally. The first generation model, launched in 2005, was the first mechanical watch I purchased for myself in my student days and while my watch, powered by the slim cal. 2500C, has seen the inside of the Omega service centre more times than I would have liked, it still has a place in my regular rotation, especially when the weather turns warm. The appeal of the Planet Ocean is its fresh interpretation of historical Omega motifs; it features details like the broad arrow hands without attempting to be a vintage remake. The collection was refreshed in 2011 and again in 2016, but it seemed to get chunkier with each new iteration, to the dismay of ...

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...

The Greatest Horological Masterpieces of All Time: the Harrison H4 – A Groundbreaking Timepiece That Solved The Longitude Problem Worn & Wound

The Greatest Horological Masterpieces of All Time: the Harrison H4 – A Groundbreaking Timepiece That Solved The Longitude Problem

A series of features identifying the most extraordinary mechanical masterpieces in history, blending precision, innovation, and craftsmanship. We all have our favourite timepieces either in our collection or those incredible horological masterpieces that have been invented or created through the ages. This series will showcase examples from the previous centuries up to the present day and look at the importance and impact on modern day timekeeping.  John Harrison’s H4 Chronometer was a groundbreaking timepiece that solved the longitude problem, a major challenge for navigation during the 18th century. Before Harrison’s work, sailors had no reliable way to determine their precise east-west position at sea, leading to deadly navigation errors. The British government, through the Longitude Act of 1714, offered a large prize to anyone who could develop a practical solution. Sir Cloudesley Shovell, by Michael Dahl, about 1702-5 (L); The Association with the Eagle, Rumney and the Firebrand, Lost on the Rocks of Scilly, October 22, 1707 (R). Image courtesy of the © National Maritime Museum, Greenwich, London The Catalyst for the Longitude Act In the early 18th century, determining longitude at sea was one of the greatest challenges in navigation. While sailors could measure latitude using the position of the sun or stars, longitude required precise timekeeping-something that was nearly impossible with the unreliable clocks of the time. The inability to determ...

Rolex Oysterflex: The Watch Strap That's Really A Bracelet Teddy Baldassarre

Rolex Oysterflex: The Watch Strap That's Really A Bracelet

Among all of Rolex’s bracelet options, the Oysterflex is perhaps the most unconventional and arguably the most misunderstood. Now marking 10 years on the market, and encompassing attributes of both a sturdy steel bracelet and a supple rubber strap, the Oysterflex has gone from being a curious, one-off outlier on a niche Yacht-Master model to an integral element of some of the Crown’s most buzz-worthy timepieces of recent years. Here’s what you should know about it. History of Rubber Watch Straps The road to the Rolex Oysterflex bracelet really started with the invention of vulcanized rubber in 1839, attributed to chemist Charles Goodyear (below, whose name is now immortalized in the automotive world as a leading manufacturer of tires). Vulcanized rubber - a compound of natural rubber with other compounds, which offered enhanced resilience and pliability - was originally used in mostly industrial areas, as in the manufacture of o-rings, gaskets, and (of course) tires. The discovery of fluoroelastomers as an alternative to the difficult-to-source natural rubber led to the rise of synthetic rubbers that had even more advantages, such as resistance to water, oils, and temperature extremes. These rubbers found their way into more everyday products such as shoes, belts, and flooring, while also expanding further into applications in the automotive industry, for door seals, hoses, and other parts. Synthetic rubber first emerged as an alternative for wristwatch straps in...

Let’s start with the name - Laureato. It’s Italian, which we happen to like here at Fratello. Roughly translated, it means “crowned for success” or “crowned with laurels,” a reward once given to winners of sports competitions and, later, to students and artists. In Italy, laurea is also the equivalent of a master’s university degree. […] Visit Video: Girard-Perregaux Laureato Fifty – A Fresh Take On A 1970s Icon to read the full article.
