Ever since Kurt Klaus developed his ingenious perpetual calendar mechanism in the early 1980s, the Schaffhausen-based manufacture has made one of watchmaking’s most sophisticated complications surprisingly easy to live with. Yet despite appearing across several generations of Portugieser, the perpetual calendar had never found its way into the collection’s sportiest member. Perhaps for a reason, […]

A. Lange & Söhne’s 1815 Rattrapante Perpetual Calendar brings together high complications, vintage-inspired design and a stunning pink-gold dial in one deeply romantic expression of haute horlogerie! What We Love Traditional pocket watch inspired vintage case design Pink gold dial suits this model perfectly and captures it in the best light Two romantic high-complications of rattrapante and perpetual calendar are showcased beautifully What We Don’t No lume for low-light legibility The case thickness may be large for some This classic pocket-watch inspired design may not be practical for daily wear Overall Rating: 9.4 / 10 Value for Money: 9.5/10 Wearability: 9/10 Design: 9.5/10 Build Quality: 9.5/10 The A. Lange & Söhne 1815 Rattrapante Perpetual Calendar is one of those timepieces that immediately reminds you why the Saxon manufacture is held in such high regard. It brings together so much of what makes German watchmaking special, but does so in a way that leaves you genuinely in awe. I recently did a video on this watch, sharing my thoughts on what makes it so special, and my opinion still has not changed: this is easily one of my top three favourite models from the brand. But enough of me drooling over it, let’s get into what makes this timepiece so remarkable. The A. Lange & Söhne 1815 Rattrapante Perpetual Calendar was first introduced in 2013 as a milestone in Lange’s modern chronograph history. As the name suggests, the timepiece brings together a rat...

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.

What is the ultimate first world problem? I can think of a handful. There’s the classic notion that we just have too much content to scroll through, stream, and consume. As the Boss put it, there’s 57 channels and nothin’ on. As I sit here typing up this article on hot early summer day with my AC blasting, I’m realizing it’s getting cold enough in here that I might need to add a layer. Woe is me! Just a few weeks ago, I bought a new iPhone and quickly found that Apple Music hadn’t automatically moved over all of my locally downloaded tunes during the initial data transfer. I was pretty disappointed when I realized only the second half of Turn on the Bright Lights was available to me on a late night drive home over the weekend. I just want to hear “Obstacle 1”! These are all annoyances, for sure. But none of them truly compare to the King of First World Problems, which is very obviously not being able to keep your perpetual calendar sufficiently wound. I mean, have you tried to reset one of these things recently? It can be really frustrating. Plenty of brands, like IWC earlier this year, have made moves to make their perpetual calendar movements more forgiving when resetting. Gone are the days, hopefully, when jumping past the current year means an expensive trip back to the manufacture in Switzerland. Vacheron Constantin has a slightly different solution, which is to enable your perpetual calendar to remain wound for weeks at a time by allowing the wearer...

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...

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...
