Which Rolex Movement Takes The Top Spot? A Watchmaker’s Comparison Of Rolex Calibers 3135 And 3235, And Which Is Better? – Reprise

Ask any watchmaker about the Rolex 31 family of calibers and the story will be the same: it has stood the test of time. Ashton Tracy hasn’t met a single watchmaker who doesn’t love working on these workhorse Rolex movements. They are easy to service, keep great time, and stand up to abuse. Put simply: they work. So how does it stand up to big brother, Caliber 3235? Find out right here!

In-Depth – The Vacheron Constantin Overseas Self-Winding Ultra-Thin, with a New In-House Calibre to Fight in the Holy Trinity Sports Watch Battle

The new Overseas Self-Winding Ultra-Thin 2500V is, without a doubt, one of Vacheron Constantin‘s most important releases of the year, not particularly for commercial reasons, knowing its low availability, but for credibility and relevance in a specific market, that of the high-end, ultra-thin integrated sports watch. Revealed at Watches and Wonders 2026, the model replaces […]

Introducing – The New Felipe Pikullik Sternenhimmel, Powered by the New Calibre FPA1 Monochrome

Introducing – The New Felipe Pikullik Sternenhimmel, Powered by the New Calibre FPA1

The path of Felipe Pikullik has never been about sudden breakthroughs, but about steady, hands-on progression. Early pieces from his Berlin atelier were built on reworked Unitas movements, extensively modified, skeletonised and hand-finished to create something much more personal than their origins suggested. From the poetic Sternenhimmel to the more expressive ZBM1, and later regulator-style […]

Introducing – The Kudoke 3 Nocturne, Alongside a New Dial and Decor Option for the Kaliber 1

German indie watchmaker Stefan Kudoke expands the HANDwerk collection with the Kudoke 3 Nocturne, keeping the core concept intact but changing its expression, much like the Nocturne edition of the Kudoke 2. This new variant builds on the Kudoke 3, previously available in various executions, including Sky Blue, salmon, and the Flakes edition with the […]

Introducing – A Duo of Audemars Piguet´s Openworked Perpetual Calendars, Powered by the Latest Calibre 7139

A perpetual calendar is a complication very much dear to Audemars Piguet. Since the mid-20th century, the manufacture in Le Brassus has offered many variations on how this “celestial” mechanism could be presented, displayed and used. From the world’s first leap-year perpetual calendar wristwatch in 1955, to the ultra-thin automatic QPs of the late 1970s, […]

First Look – The Venezianico Redentore Utopia II Enhances Italian Watchmaking with the Refined V5001 Calibre

Founded by brothers Alberto and Alessandro Morelli in 2017, the Venice-based brand was initially launched as Meccaniche Veneziane. The company got noticed with the Nereide diver and the Redentore dress line before rebranding in 2022 to strengthen its identity and link to Venetian craftsmanship. The Redentore Utopia II, after the 2024 Redentore Utopia, is the […]

First Look – Girard-Perregaux Launches the Calibre GP4800, its Next-Gen, In-House Movement with a Silicon Escapement

Girard-Perregaux has an extensive track record in watchmaking and is one of the most enduring integrated manufactures of the Swiss watch industry. In the 1980s, at a time when the quartz crisis had crippled mechanical watchmaking, the brand was among the first to champion the renaissance of traditional movements. Today, Girard-Perregaux announces the launch of […]

In-Depth: Girard-Perregaux Debuts All-New Automatic Calibre

Girard-Perregaux (GP) has just taken the covers off a new in-house movement that will serve as a versatile platform for the brand, the Girard-Perregaux GP4800. Historically a significant producer of automatic movements, GP marks a milestone with the new, high-performance base movement that will gradually replace the 3000 family of movements that was once a workhorse employed by several high-end brands. Initial thoughts GP’s most famous creations are undoubtedly the historical Tourbillon with Three Gold Bridges and the more recent Constant Escapement. Significant as they may be, neither illustrates the brand’s past strength as a manufacture in the early decades of contemporary watchmaking post-Quartz Crisis, in particular GP’s position as a leading supplier of automatic movements.  It all began with the 3000 family of calibres introduced in 1994. Desirable for its slimness and high performance – the 3000 series was sub-3 mm thick while ticking at 4 Hz – this versatile platform served not only as a base for many of the brand’s own timepieces, but also powered well-known watches made by a number of prominent brands, including Cartier, Daniel Roth, Vacheron Constantin, and even MB&F;. A GP3000 found in the MB&F; HM2 And then inverted in the MB&F; HM8 Mark 2 The new GP4800 is clearly meant to replace the venerable-yet-aging 3000-series. Boasting a modern architecture and fine technical chops, the GP4800 is a step towards reclaiming GP’s past success as a movement ma...

Introducing – The Singer Caballero, the Brand’s Take on a Time-Only Watch with the New Calibre-4

Singer Reimagined has spent the past eight years experimenting with what independent watchmaking can look like. The Geneva-based brand, founded by Rob Dickinson of Singer Vehicle Design and designer Marco Borraccino, established its name with the radical Track 1 chronograph, powered by Agenhor’s Agengraphe. It was followed by the stripped-down Flytrack, the diving-oriented Divetrack, and […]

In-Depth – Deciphering the Revolutionary Rolex Dynapulse Escapement and the Calibre 7135

Rolex has changed… Not marginally, but significantly. We knew the brand was capable of being rather unpredictable and capable of bold creative moves, such as bubble-decorated dials and watches with a guilloché pattern. The days when Rolex simply revamped a collection every 10 years by implementing incremental upgrades and releasing new dial colours every two […]

First Look – The New-Gen AP Royal Oak Perpetual Calendar Selfwinding with the New Calibre 7138

About a year ago, when Audemars Piguet held its yearly event to present its new collection, the brand introduced a highly appealing version of the Royal Oak Perpetual Calendar Selfwinding, made with artist and seasoned collector John Mayer. Besides the incredibly textured dial, AP issued a highly important statement. This watch marked the swan song […]

First Look – The new Nomos Tangente 2date, and The new In-House Calibre DUW 4601

If you’ve been following Nomos for a while, you certainly know that despite a certain German rigour and classic minimalistic inspiration (so-called Bauhaus), the Glashütte-based brand doesn’t like to do things too seriously – at least, design-wise. Small touches of colour, original shapes and a youthful approach are key elements of the brand’s design language. […]

First Look – The New TAG Heuer Monaco Chronograph Racing Green Calibre 11 in Titanium

Racing green… Probably one of the most emblematic colours in motorsport. We have to remember that, in the early days of car racing, colours were not just decorative, but racing drivers competed with liveries representing their country – Italian red, German silver, French blue (featured in last year’s limited edition) and, of course, British racing […]

The Evergreens – The History of the ETA 2824, the Workhorse Calibre that Shaped the Industry

The ETA 2824 movement was a groundbreaking invention that left a lasting impact on the watchmaking industry. Introduced in the 1970s, the ETA 2824 quickly set the standard with its efficient mass production and reliable performance. It retained its popularity for over fifty years until the circumstances and demand for innovation led to the creation […]

First Look – The Grand Seiko Pink Snowflake SBGA497, Celebrating 20 Years of the 9R Spring Drive Calibre

Even though its development started during the 1970s, it took some years for Seiko and Grand Seiko to finally present their first movement equipped with the Spring Drive technology (the very first was a Seiko in 1999). In 2004, after more than 2 decades of research, the first generation of Grand Seiko Spring Drive was […]

Daniel Roth Unveils Tourbillon Souscription and DR001 Calibre SJX Watches

Daniel Roth Unveils Tourbillon Souscription and DR001 Calibre

With Daniel Roth’s revival having become official last year, the brand has just taken the covers off the prototype of the Daniel Roth Tourbillon Souscription at LVMH Watch Week 2024. Retaining the style and dimensions of its 1990s inspiration, the Tourbillon Souscription is, however, an entirely new creation in mechanical terms, with the DR001 movement inside having been developed specifically for it by Geneva complications specialist La Fabrique du Temps (LFT). Initial thoughts The prototype of the Tourbillon Souscription arrives with subtle refinements compared to the images released last year. The aesthetics largely replicate the design of the 1990s originals, which was the brand’s goal from the beginning, at least for this opening act in its revival. Where the Tourbillon Souscription does better than the original is in the execution and mechanics. The guilloche dial is evidently top quality and also on a solid-gold base. More notably, the recessed area around the tourbillon, which is the actually the base plate, is finished with Côtes de Genève. On the originals this area was unfinished except for a rudimentary micro-blasting. But the calibre within is a more substantive achievement. The DR001 movement was conceived for this watch (though perhaps borrowing elements from LFT’s existing constructions) with aesthetics and traditional detailing in mind, explaining elements like the black-polished steel cock and linear winding click. In contrast, the originals relie...
