Happenings: Roger W. Smith OBE To Lecture At The Horological Society Of New York

At the June 2026 lecture of the Horological Society of New York (HSNY), independent watchmaker Roger W. Smith OBE will trace the remarkable story of the co-axial escapement from George Daniels' original invention in the early 1970s through to its continuing modern evolution. Beginning with Daniels' determination to address the fundamental limitations of the Swiss lever escapement, the talk explores the development of his early experimental pocket watches, together with the long and often difficult process of persuading a skeptical Swiss watch industry to adopt an entirely new escapement system. Drawing on firsthand experience working alongside Daniels during the Millennium Watch project and the launch of the first Omega co-axial wristwatch in 1999, Smith will provide a rare personal insight into a pivotal moment in modern horological history. The second half of the presentation will examine the subsequent technical evolution of the escapement from 2005 onwards, including the development of the single-wheel co-axial and the changing philosophy behind escapement design — moving beyond pure chronometric performance towards long-term stability, durability, and extended service intervals.

Pondering Swatch’s Relevance: Is Adrenaline-Fueled Hype Enough To Remain A Player In The Watch Game?

Hype around Swatch is not new. The “Second Watch,” launched in 1983 as a fun and affordable accessory you could wear to match your daily outfits, was never meant to be a lifelong heirloom investment. It was always about the heat of the moment.

Formex Introduces the Aria, an Integrated Bracelet Sports Watch with a Manufacture Movement

Formex has formally introduced what is likely to be at or near the top of many of our “Watch of the Year” lists when 2026 is all said and done. Long a brand synonymous with squeezing an absolutely insane amount of value from every dollar spent, the new Aria is Formex’s most ambitious watch to date, by a wide margin. We got a look at the Aria during Watches & Wonders week while Formex exhibited at Chronopolis, and then again at Windup San Francisco a few weeks later, and we remain impressed with what the brand has accomplished. This is a big step forward for them on a number of fronts.  The Aria is an integrated bracelet sports watch that is also ultra-thin and uses the brand’s first manufacture movement. It makes sense, I think, to start with the case and bracelet, because they are immediately striking to hold and wear when you first experience the watch. The Aria is 40mm in diameter and crafted from titanium, with a tapered bracelet that has meticulously hand finished elements throughout. The total case height comes to just 6.9mm, and a close examination of the case, bracelet, and how they are integrated to one another reveals an intense attention to detail on the part of Formex and their design team. The Aria seems to understand what makes an integrated bracelet sports watch really work, which is a continuity of form from the case to the bracelet, and all the way to the clasp. They are integrated in the truest sense of the word, with matching finishes and tight ...

Zenith Chronomaster Revival Liberty II May 28, 2026

Introducing: The Zenith Chronomaster Revival Liberty II Limited Editions (Live Pics)

What We Know Today, Zenith introduces two new takes on its distinctive tonneau-shaped A384 chronograph, a modern revival of the model from the late sixties. The new Chronomaster Revival Liberty II is a sequel to the Chronomaster Revival Liberty from 2020, which paired a distinctive red and white striped chronograph seconds hand with a blue dial and white subdials. For the Revival Liberty II, two models are introduced: a stainless steel variant in a run of 250 pieces, and a forged carbon edition in 25 pieces. The theming, as you might guess from the name, focuses on the 250th anniversary of the United States in these US-exclusive editions. Both editions feature that red and white striped chronograph seconds hand (13 stripes for the original 13 colonies). These follow-ups to the original take the blue and white scheme and invert it, with this new dial featuring a white lacquered base with contrasting blue subdials and tachymeter. "250" on the tachymeter scale is highlighted in red in light of the anniversary. The forged carbon edition offers a much more contemporary look, with swirls of silver and black in the ultralight case, pushers, and crown, and paired with a blue textile-embossed rubber strap. The steel version comes with two strap options—a ladder bracelet in stainless steel, as well as a rubber strap for a bit of extra versatility. The case dimensions remain identical to all other A384 revival editions, with a 37mm diameter and 12.6mm thickness. The movement inside...

The Barrelhand Monolith Takes Flight SJX Watches
Omega Speedmaster Skywalker X-33 But May 28, 2026

The Barrelhand Monolith Takes Flight

First teased more than two years ago, the Barrelhand Monolith makes its official debut. An impressive sophomore effort from San Francisco-based mechanical engineer Karel Bachand, the Monolith was designed — and rigorously tested — to accompany the next generation of manned spaceflight missions. Initial thoughts I tend to look at astronaut-oriented watches with a degree of scepticism. For one thing, many modern mechanical watches are inherently capable of performing well enough in space, especially within the pressurised, temperature-controlled conditions of a spacecraft or space station. Today’s astronauts often travel with numerous personal watches, either for sentimental reasons or to boost future resale value. For another, the demands placed on astronauts make electronic multi-function watches superior to their mechanical counterparts. Almost as soon as such watches were developed, astronauts adopted them enthusiastically, which is why the Timex Datalink was flight qualified by NASA in the 1990s. The European Space Agency (ESA) even patented a set of purpose-built functions devised by astronaut Jean-François Clervoy. These functions were brought to life by the Omega Speedmaster Skywalker X-33. But mechanical watches still have a place in the unforgiving vacuum of space, where massive temperature fluctuations and unpredictable levels of radiation wreak havoc on batteries and LCD displays. These are the conditions for which the Monolith was developed, and the maker...

There are tool watches, and then there are watches that make conventional tool watches look almost quaint. The Barrelhand Monolith belongs in the latter category. This timepiece took six years to develop. Aerospace engineering, additive manufacturing, and advanced materials science were used to create not simply a “space-inspired” watch but an actual instrument for modern […] Visit Blastoff For The Space-Going Barrelhand Monolith — A Next-Generation Mission-Grade Space Watch to read the full article.

Introducing: The Barrelhand Monolith Has Landed

After six years in development, Barrelhand is formally launching the Monolith, a watch that represents a new generation of the tool watch genre built explicitly for the space age. Watches have played an important role in the history of human space travel, but few have actually been designed and engineered to meet ISO aerospace standards, NASA material guidance, and EVA/IVA testing protocols consistent with the needs of a crewed deep-space mission. The Monolith represents exactly that, with Barrelhand going to great lengths to meet a standard that tool watches are rarely held to these days. At the dawn of the Apollo program, with five years of learning from the Gemini program under their belt, NASA issued a memorandum outlining the need for a standard flight-crew wrist watch. The story that follows is a widely known part of watch lore, with Omega's Speedmaster ultimately earning the coveted "Flight Qualified" status, and thus a spot on every crewed flight of the Apollo program from 1968 to 1972. The testing protocols developed by NASA put a handful of commercially available watches through a battery of tests that included exposure to extreme temperature, pressure, and shock, and while none would ace the testing, the Speedmaster came out the other end in arguably the best shape. It's important to note that none of the watches selected by NASA's Procurement and Contracts Division were built with these tests in mind. The Speedmaster and the Daytona were both built with automot...

Review: The Fears Arnos Pewter Blue Worn & Wound
Christopher Ward May 27, 2026

Review: The Fears Arnos Pewter Blue

Four years ago I spent a fortnight with the Archival 1930, and ultimately proclaimed it the closest Fears has come to parting me from my hard-earned money. Since then, two things have happened. Firstly, Fears did earn my business by way of the Alliance 01 collaboration with Christopher Ward. Secondly, the modest lineup of rectangular watches from the brand has grown ever so slightly but remains overshadowed by the flagship Brunswick and sporty Redcliff families, and are perhaps therefore a little underappreciated. With so many iterations based on the Brunswick template, including the hugely popular cocktail trilogy produced in collaboration with Studio Underd0g, I find myself rooting for the Arnos – Fears’ first watch to build on the template of the Archival 1930 which captured my heart. When analyzing the Arnos ($4,500), it feels appropriate to start with the dial. I haven’t sought out common opinion in preparation for going hands on with the watch, but I fully expect the dial to be a polarizing factor. As is the case with any rectangular watch, there’s going to be a lot of space to fill. Space where the hands just can’t reach. That’s true of square dial watches too, but exacerbated further in a rectangle. Some watches fill this space with stretched indices, or an inner minute track matching the same outer rectangular shape. Even the aforementioned Archival 1930 (in two-hander form) lined the indices up vertically to cleverly use the corner spaces. Here, howev...

Hands-On: A Triple Review Of The Jaeger-LeCoultre Master Control Chronomètre Collection

We're a few months removed from Watches & Wonders, which gives us some clarity about what was buzz, what was hype, what fell off the wish lists, and what will be a long-term winner. It's looking like Jaeger-LeCoultre had one of the best releases of the fair with the Master Control Chronomètre series. The Master Control line has largely been a dressy take on traditional design cues for a brand people usually think of first for its Reverso. But now, JLC has shown that Master Control can do more. More than just a new case and bracelet, all watches are in-house chronometer-certified 4Hz, 70-hour power reserve movements (COSC does the certification) with a new High Precision Guarantee (HPG) seal, which supplants the former 1000 Hours Control. That new HPG seal means that the brand trials cased watches on four daily-wear specific issues—shocks, positions, altitude, and temperature—over three days, while guaranteeing eight traditional techniques of quality aesthetic finishing. The watches I photographed were brand new and wrapped in plastic, so you have to look past a bit of that to see the quality, but it certainly is there in person. Now with three models in steel and rose gold, with five SKUs (one watch only comes in steel and not gold), measuring 38mm by 8.4mm or 39mm or 9.2mm with 50m of water resistance, the new line brings a lot to the table. Inspired by the brand's Master Mariner Chronomètre line, launched in 1973 as their offering for an integrated bracelet (or adj...

Dennison x Collectability’s Second Collab Gives Us Four Funky Twists on Its Inaugural Offering

While some brands regularly take the collaborative approach, this hasn’t been the case for Dennison. Its first co-designed model came to us just about a year ago when the Maison first teamed up with Collectability, the brainchild of Patek Philippe expert and horological icon John Reardon. The pair’s initial offering achieved an impressive balance of design language. It combined some clear inspiration from Patek’s Ellipse as well as some of the brand’s lesser-known models with elements of the collection that revived Dennison in the modern era – the A.L.D. – developed by acclaimed watch designer Emmanuel Gueit, whose resume includes the Rolex 1908, Harry Winston Z1, and Audemars Piguet Royal Oak Offshore. The duo has just spun up its second collaboration, available for pre-order for one week only, beginning today through June 3. If you didn’t immediately click over to place an order, and you’re still with me, let’s unpack these latest additions. The new Oblique collection certainly has echoes of the original co-design but with a little bit more edge. The pair’s inaugural offering was relatively classic and timeless whereas the latest interpretations are a bit more modern and sculptural. This time, Dennison and Collectability give us two variations: the bold Enigma dial and the more sober Vector dial. In both iterations, the brands lean further into the funky design language that began emerging in the 1960s with asymmetry being a focus. Here, the familiar ...

Highlights: Notable Independents at Phillips Hong Kong

Phillips’ spring auction season wraps up with The Hong Kong Watch Auction: XXII on May 30 – 31. As is now the norm, independent watchmakers have carved out a significant section of the catalogue including the usual suspects from F.P. Journe and Philippe Dufour, as well as rare showings from under-the-radar makers like Oscillon and Yosuke Sekiguchi. Lot 878 – Oscillon L’instant de Vérité Despite how hot the indie segment has become, Oscillon has largely stayed under the radar, perhaps due to its intensely cerebral nature, or because the brand only produces about five watches per year. The duo behind the brand, Dominique Buser and Cyrano Devanthey, are collectors of pre-computerised watchmaking machines. Their collection is so extensive that they can produce all movement parts – save for the jewels and shock protection – under their own roof using these machines. Even putting this context aside, the watches themselves are still mechanically interesting. The most striking detail is the bowtie-shaped balance, which is harder to poise and less aerodynamic than a conventional annular balance, but looks much cooler. L’instant de Vérité uses an unusual tensator constant-force spring. To explain this, consider a tape measure. The force required to pull more length from a tape measure doesn’t noticeably increase regardless of the length already paid out. Now imagine hooking the end of the tape to a pulley, so that turning the pulley (winding) pulls tape out, and ...

Introducing: H. Moser & Cie. Endeavour Flyback Chronograph Dual Time Date Hodinkee
H. Moser & Cie Endeavour Flyback May 27, 2026

Introducing: H. Moser & Cie. Endeavour Flyback Chronograph Dual Time Date

What We Know H. Moser & Cie. introduced its first flyback chronograph in 2020 with the Streamliner, a cushion-cased sports watch powered by the HMC 902—an automatic movement with central elapsed-seconds and elapsed-minutes hands and no sub-dials. That watch won the Chronograph Watch Prize at the GPHG and gave rise to a full collection. The next step was always the Endeavour case, and today it's here. The Endeavour Flyback Chronograph Dual Time Date takes the core architecture of the HMC 902, removes the automatic winding system, and uses the freed space to add a second time zone and date—all without any subdials The Endeavour Flyback Chronograph Dual Time Date comes in a 42mm stainless steel case with chronograph pushers at 10 and 2 o'clock and a screw-down crown at 4 o'clock. The dial is a turquoise fumé with a sunburst pattern. The central disc—which carries the second time zone—is in Blackor fumé, also with a sunburst pattern. Around the perimeter, a tachymeter sits on the flange alongside a white minute track that handles both elapsed seconds and minutes for the chronograph. Hands are leaf-shaped and filled with Super-LumiNova, as is the tip of the dual-time arrow. Uniting three complications—a flyback chronograph, a second time zone, and a date display—the watch does away with traditional subdials entirely. Instead, all indications are centralized: a red hand tracks chronograph seconds, a rhodium-plated hand shows elapsed minutes, and the second time zon...
