The perpetual calendar is one of the most fascinating watchmaking complications. It can also be one of the most frustrating. Capable of automatically accounting for irregular month lengths and leap years, it is a mechanical marvel, yet one that often requires patience and caution when adjustments are necessary. With the new Récital 31, Bovet joins […]

What We Know Vacheron just brought back its incredibly unique Traditionelle Twin Beat Perpetual Calendar, and it's a welcome sight for dedicated collectors of the brand, along with general enthusiasts of unexpected yet innovative takes on complicated watchmaking. If you're not familiar with the original Traditionelle Twin Beat Perpetual Calendar, launched back in 2019, the watch offered an incredibly novel solution to a problem often found within perpetual calendar watches. Let's be honest, though the entire appeal and genius of the perpetual calendar is for someone wearing one watch all day, every day, for the whole year, watches like these are most often owned by those with a large collection to begin with. A weekend for a perpetual calendar in a watch box or drawer would mean that the complication would need to be set again after winding, and so Vacheron introduced this perpetual calendar with a whopping 65-day power reserve. To achieve this, rather than putting in an unfeasibly large mainspring in the barrel, the Traditionelle Twin Beat Perpetual Calendar lives up to its name by offering a new system that allows for switching between two beat rates for the watch—a contemporary high-beat 5Hz frequency with a 4-day power reserve for normal timekeeping during wear, but a much slower 1.2Hz mode with that prolonged power reserve for the "Standby" phase. The Caliber 3610QP comprises two separate gear trains for the two regulating systems, with a series of differentials tha...

As Raymond Weil comes out of their shell, so do more incredible timepieces. But have they hit a new peak with the Freelancer Complete Calendar? Let’s find out! What We Love: An elegant and versatile design Quality-of-life upgrades to a classic complication Excellent value proposition with few competitors What We Don’t: Movement finishing somewhat lacklustre The calendar is hard to see from a distance Do we need the lume? Overall Rating: 9/10 Value for Money: 9/10 Wearability: 9/10 Design: 9/10 Build Quality: 9/10 This article was originally published as Is The New Raymond Weil Freelancer Complete Calendar Their Best Yet? There’s a rapid surge happening in watchmaking right now. No, I’m not talking about the newly imposed 39% U.S. tariffs on Swiss watches (though that’s a story in itself), but rather the quiet re-emergence of the middle market. As household names climb further upmarket, a new wave of brands are pushing harder than ever, flexing their creative and horological muscles to prove what they’re truly capable of. Christopher Ward is one; Frederique Constant and Maurice Lacroix are others. But perhaps the most impressive contender in this power shift is none other than Raymond Weil. Nearly 50 years young, the family-owned independent has been quietly racking up achievements and accolades. Their breakout moment came with the GPHG-winning Millésime collection, followed by ambitious world timers and flyback chronographs — complications that once f...

Anyone familiar with H. Moser & Cie.’s Concept watches knows that ‘concept’, in the brand’s vocabulary, means extreme minimalism with dials purged of logos, indices and numerals.

Roger Dubuis’ latest releases at Watches and Wonders are steeped in the brand’s history. For the occasion, the maison introduces two complicated pieces – a perpetual calendar and day-date calendar – each in the brand’s patented biretrograde display. Prior to founding his namesake maison, Mr. Roger Dubuis was a prolific watchmaker for several brands, from Patek Philippe to Longines. One such project came in 1989 when he and fellow watchmaker Jean-Marc Wiederrecht collaboratively pioneered and patented their famous biretrograde display, which reworked the traditional concept and made it more streamlined. This approach eased assembly and improved the stability and readability of the hands on the ecliptic retrograde counters. Soon after, the pair engineered a double retrograde perpetual calendar module, which was notably used in a timepiece for Harry Winston. A year after the brand’s official founding, Roger Dubuis introduced its own biretrograde display timepiece and later the perpetual calendar complication in its iconic Sympathie and Homage collections. Today, we see the next evolution of these concepts highlighted in a rather modestly sized 40mm version of its Excalibur line. The Excalibur Biretrograde Perpetual Calendar is notably powered by an entirely new movement: the RD850. Here, the maison builds upon the work set forth four decades ago with a self-winding caliber built from 435 components in-house at Roger Dubuis’ Geneva manufacture. A key functional i...

Audemars Piguet (AP) has updated the coveted Royal Oak Perpetual Calendar Openworked, which makes its debut on the next-generation perpetual calendar platform that debuted last year. The new calibre allows for individual adjustment of each calendar indication using just the crown – no stylus (or toothpick) necessary. The first outing for the skeletonised version of this class-leading perpetual calendar is in titanium, with mirror polished accents in scratch-resistant Palladium BMG and pops of rose gold on the dial and case back, though more colourways are sure to come in due time. Initial thoughts The latest generation of the Royal Oak Perpetual Calendar is arguably AP’s strongest product. It is heir to the archetypal integrated bracelet perpetual calendar sports watch, which, until recently, was held back to some extent by what had become a dated movement. In fairness, the same can be said of its obvious competitors from Patek Philippe and Vacheron Constantin. That changed in 2025 when the Royal Oak Perpetual Calendar was upgraded with the AP’s latest perpetual calendar movement, a significant release befitting the brand’s 150th anniversary year. The calibre 7138 introduced individual correction of the date, day, month, and moon phase using only the crown, allowing for quick adjustment without tools and with greater flexibility, and support for more indications, than existing solutions. And while we already understood the movement’s clever functionality, it rema...
