Does The A. Lange & Söhne Datograph Up/Down Deserve Its Icon Status? (Review)

A pink gold Datograph Up/Down with serious chronograph engineering, rich contrast, and the kind of finishing only Lange can deliver. What We Love: Beautifully executed 18-carat pink gold case is as elegant as it comes! One of modern watchmaking’s great chronograph movements, showcased through a rich black and pink gold dial execution. Wears far better than the dimensions suggest. What We Don’t: Case thickness may be too large for some by modern standards. Dial layout may feel slightly imbalanced with integration of power-reserve indicator Traditional 2.5Hz beat rate may not appeal to those who prefer higher-frequency chronograph movements. Overall Rating: 9/10 Value for Money: 9/10 Wearability: 9/10 Design: 9/10 Build Quality: 9.5/10 There are very few brands in the world of watchmaking that can do what A. Lange & Söhne is capable of. The brand’s chronographs are also some of the most respected timepieces in the industry, carrying heritage, incredible craftsmanship, and painstaking assembly methods that place their movements among the best in the world. Fortunately for me, I had the chance to get up close and go hands-on with one of the brand’s signature chronographs: the Datograph Up/Down. One of the original 1999 A. Lange & Söhne Datograph models (Ref. 403.035) The Datograph was first introduced in 1999, and it quickly became one of the benchmark chronographs of modern watchmaking. Why did it rise to such a status so quickly? It was because of the model’s...

H. Moser Introduces the Endeavour Flyback Chronograph Dual Time Date, with a Brand New Manually Wound Movement Worn & Wound

H. Moser Introduces the Endeavour Flyback Chronograph Dual Time Date, with a Brand New Manually Wound Movement

Moser’s new Endeavour Flyback Chronograph Dual Time Date occupies a strange niche which the brand has now explored twice in the span of just a few months: a watch with a movement that has been converted from an automatic version to manually wound for additional functionality and convenience. I’d be surprised if this was an operating principle for Moser for either this release or the Streamliner Pump which debuted at Watches & Wonders, and runs on the HMC 103, which is a manually wound version of their workhorse HMC 500. But it does speak to the brand’s ingenuity when it comes to movement making, and is a reminder that while Moser’s aesthetics and distinct design language often get the most ink, there’s real watchmaking happening as well.  Moser’s Endeavour platform gets the debut of an entirely new movement from Moser, the HMC 730. Based on the architecture of the HMC 902, their automatic chronograph movement made with AGENHOR, the new caliber dispenses with an automatic winding system in favor of dual time and date complications. It does all of this without traditional subdials, a real benefit of the proprietary AGENHOR architecture, which promises a more intuitive readout of elapsed time on a chronograph. On this watch, a red central hand tracks chronograph seconds, a rhodium plated hand tracks elapsed minutes, and the second time zone is found within an interior gray fume dial.  The movement has a number of function first technical advances. The date, for ...

Review – Exploring Chinese Watchmaking, with the Peacock Divine Ultra-Thin Tourbillon (Incl. Video)

Chinese watchmaking is often frowned upon at best, but things have changed in the past few years. More often than not, we categorise Chinese watches as entry-level (to remain polite) or counterfeits. No need to say, this is very simplistic. But we have decided to forget our prejudices and to make up our minds by taking […]

Hands-On: Hamilton Khaki Field Mechanical 36mm – The Return Of A Vintage Military Legend

As the United States of America celebrates 250 years since the signing of the Declaration of Independence this year, reflecting on two and a half centuries of history, Hamilton is also looking back on its past. Instead of the 1770s, however, the Swiss-based watch brand has drawn inspiration from the 1970s and has announced the release of the Khaki Field Mechanical 36mm, a virtually 1:1 recreation of the famed 36mm Hamilton FAPD-5101 Type 1 created as a navigator's watch for the U.S. Air Force in the 1970s. The Hamilton Boutique in Lancaster, PA - formerly the Bowman Technical School for watchmakers. The FAPD-5101 Type 1 variant was produced in September of 1970 and was intended for use by U.S. Air Force personnel during the Vietnam War as a navigator's watch. While Hamilton also produced many other watches for the U.S. Military throughout the 20th Century, this particular piece was unique in that it was slightly larger and therefore more legible than its contemporaries. Due to its modern proportions and rarity, it remains highly prized among vintage watch collectors today. Hamilton's American Roots The launch of the watch was celebrated in Hamilton's ancestral home of Lancaster, Pennsylvania, just ahead of Memorial Day Weekend. Hamilton was founded in 1892 in Lancaster, where a budding watch industry had been struggling for several years to get off the ground. Seeing the need and potential for high-quality watches in the booming railroad industry, a consortium of local ent...

The Countdown is on to Get the Next Chapter in Micromilspec x Black Badger’s Time Wars: the Broken Hour

Collaboration has been at the core of watchmaking since the early days with the etablissage system on which the artform was founded joining together craftspeople of all disciplines to bring a watch to life. In our modern era, collaborations have become more formalized between watchmakers as well as with other brands, artists, athletes, and even the most unexpected partners. Yes, collaborations have taken some wild twists and turns, and the work between Micromilspec’s founders Henrik Rye, Alexander Kadin, and Kim Ellefsen alongside industrial designer and materials specialist James Thompson AKA Black Badger definitely falls in that category. The group first teamed up one year ago for the inaugural installment in the Project Sabotage/Time Wars series, but what makes this collaboration so unique is that it extends beyond the watch itself and to an accompanying alternate anime universe. Here, Micromilspec and Black Badger have taken the concept of storytelling in watchmaking to a whole new level, placing their co-created timepiece in its own world where Black Badger himself takes his animal form. As you might guess, the creative process throughout such a collaboration is anything but ordinary.  I sat down with Black Badger himself just ahead of the announcement for the second edition in the series the Broken Hour, whose one-time, 24-hour sales window is officially open and closes at 12pm ET on May 30. “Henrick and I were just together finalizing the storytelling elements,...

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. Due to limited seating, tickets will be released according to this schedule: Gold Members...............May 26 (12 PM ET)Silver Members..............May 28 (12 PM ET)Bronze Members............June 2 (12 PM ET)General Public................June 4 (12 PM ET) A dedicated email with a unique cod...

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. The colorful plastic Swatch caused a massive cultural and commercial “uproar” […] Visit Pondering Swatch’s Relevance: Is Adrenaline-Fueled Hype Enough To Remain A Player In The Watch Game? to read the full article.

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 ...

Albishorn Introduces the New Type X-Graph Worn & Wound

Albishorn Introduces the New Type X-Graph

Swiss brand Albishorn is known for their rather daring mission of recreating vintage watches that never existed; a goal that seems confusing until you see their wide swathe of “imaginary vintage” offerings, each of which draws from iconic timepieces of the past while forging their own new identities. It’s an exercise in parallel history with an added touch of impossibility, and it’s what makes Albishorn watches a category of their own. Carrying on that hypothetical tradition is the new Type X-Graph, which borrows elements from the legendary Type 20 design, while adding features that were simply not possible in the era that Type 20 pieces were being built.  Rather than taking a Type 20 silhouette and cramming new features in, Albishorn has taken to imagining what a predecessor “Type 10” may have looked like instead. Calling it a “missing link” in the history of the Type 20, the Type X-Graph is, of course, a pilot chronograph, with stylings from the late 1940s to pre-date the Type 20’s 1950s introduction. A monopusher military chronograph design, the Type X-Graph measures in at 39mm (a first hint of the modern innovations that remind us that it’s of an imagined history) in case diameter, and 20mm in case thickness. The lug width is a democratic 20mm, with the final lug-to-lug measurement coming in at a wearable 47.7mm, and kept slim by the 12mm thickness. But that’s just the boring stuff; the visuals and functionality of the X-Graph are what make it st...

Zenith Introduces the Chronomaster Revival Liberty II in Stainless Steel and Forged Carbon

Back in 2020, Zenith released the Chronomaster Revival Liberty, a North American exclusive limited edition that is still one of the most popular of the A384 reissues we’ve seen. In fact, you could probably make a case that the early success of this particular A384 revival laid the groundwork for all that came after (and there have been many of these A384s released in the last six years). The original Liberty, with its red and white chronograph seconds hand and subtle blue fumé dial, was an attractive watch regardless of whether you saw it as part of a patriotic exercise. So it’s no surprise that Zenith has gone back to the well with the new Chronomaster Revival Liberty II. Coming as it does in the year of America’s 250th anniversary, the brand is leaning a bit harder into the connection Zenith has always had to the United States with this release.  Part of the conceit of the Chronomaster Revival Liberty II is that Zenith’s founder, George Favre-Jacot, was inspired by the watchmaking industry in America in the way he built the Zenith brand. In the middle part of the 19th century, the Swiss watch industry worked largely on an éstablissage system, which meant individual components were to be produced separately before final assembly. When Favre-Jacot visited the United States as a young man, he encountered a much more industrialized and efficient way of making a watch, which served as a model for the early days of Zenith.  To that end, the Chronomaster Revival Lib...
