Introducing: Fredrique Constant Manufacture Classic Perpetual Calendar Burgundy Limited Edition (Live Pics)
What We Know Last year, Frederique Constant released its classic perpetual calendar with a new movement, the FC-776, and eighteen months later, the brand is releasing a burgundy edition of its Manufacture Classic Perpetual Calendar, limited to 100 pieces. As Mark wrote when the previous edition was released right before last year's Watches and Wonders, the watch "has been one of if not the premiere affordable mechanical perpetual calendar on the market," and with the burgundy edition, the brand is offering a limited edition option to the collection. The polished stainless steel case measures 40mm by 12.25mm and has an anti-reflective convex sapphire crystal, 50 meters of water resistance, and an engraved case back carrying the individual edition number. The sunray-finished dial shifts from deep wine tones to brighter reflections, with a Côtes de Genève pattern on the counters. The day sits at 9 o'clock, the date at 3 o'clock, and the month and leap year at 12 o'clock. The moonphase at 6 o'clock runs against a midnight-blue background with laser-engraved stars. A chemin de fer minute track, applied faceted hour markers, and polished hands, and the fluted onion crown complete the dial. The Manufacture Classic Perpetual Calendar Burgundy Limited Edition, comes on a black alligator strap with a folding buckle and includes a second strap in burgundy alligator with an easy-open deployment clasp. It is priced at $12,995, limited to 100 pieces, and is available now. What We Thin...

First Look - Frederique Constant Dresses Its Attainable Perpetual Calendar in Burgundy
Frederique Constant is known to make traditionally expensive watchmaking complications more accessible. Its Manufacture Perpetual Calendar, first introduced in 2016, was a QP priced well below that of many established competitors. In 2025, the watch received an update: a more refined 40mm case and a revised movement, with a power reserve extended to 72 hours. […]

RGM Introduces the New 501-PC Perpetual Calendar
RGM has introduced a new perpetual calendar, their first since the Model 103-R Minute Repeater Perpetual which was introduced in the 1990s. The new watch, dubbed the 501-PC, has classic RGM aesthetics and incorporates a new module from Dubois-Depraz for the calendar complication (not unlike another perpetual calendar to debut recently). While the watch is not inexpensive by any means, the use of a module fixed to a mass produced movement does keep costs down somewhat compared to a fully in-house design, and serves as another example of the many small ways traditional higher end complications are being democratized across the larger watch marketplace. The 501-PC has a fairly traditional perpetual calendar layout, with a 12:00 subdial indicating the months and leap year, a 3:00 subdial showing the date, a moonphase at 6:00, and the day of the week in a subdial at 9:00. The dial layout and design takes inspiration from 19th century pocket watches, a frequent source of inspiration for RGM over the years, and is rendered in white enamel. Black painted Roman numerals and blued hands add additional depth and historic coherence to the design. It’s all very traditional and the antithesis of flashy. Again, exactly what you’d expect from RGM. The case is stainless steel and measures 39mm in diameter and is 11.5mm thick. Like the Fears linked above, which this watch is sure to draw comparisons to thanks to the movement, that’s an incredibly wearable and approachable size. The ...

Introducing: The Patek Philippe Reference 5978P - A Brand New Perpetual Calendar Chronograph! (Live Pics)
Reporting directly from Milan, we have a brand-new watch from Patek Philippe, and man, this is a big one. For only the seventh time in the 187 years of the world's most important high-end watchmaker, we have a new perpetual calendar chronograph! The 1518 was shown in 1941, the 2499 in 1951, the 3970 in 1986, the 5020 (forgot about that one, didnt ya!?) in 1994, the 5970 in 2004, and the 5270 in 2011 – which means this new watch, the reference 5978P, is only the second to be shown in my entire career covering this space. So you can imagine how excited I was to hear about it! Say hello to the 5978P. For only the seventh time in 187 years, we have a new perpetual calendar chronograph! What you're looking at is something so familiar, and yet so different. It is the first hand-wound perpetual chronograph to feature an instantaneous calendar mechanism, all shown in windows along a curved arch at the top of the dial, making the watch immensely legible, much more so than any previous PPC to date. The instantaneous jumping – which happens within 30 milliseconds – is one heck of a party trick. If you're thinking this looks like something you may have seen in the 5208 or 5308 Grand Complications, you'd be exactly right. The long and short is that Patek has taken that ingenious instantaneous perpetual calendar mechanism from its big, big dog watches and applied it to the base chronograph caliber CH 29-535 that powers Patek's finest watches. It makes a shocking amount of sen...

Introducing: Vacheron Constantin's 30th Anniversary Overseas Perpetual Calendar Ultra-Thin Limited Edition
What We Know The hottest Vacheron Constantin collection is celebrating its thirtieth anniversary this year, and the brand is paying tribute with a new version of one of my personal favorite watches from the brand. Sure, earlier this year we got the return of the 2500V, which is celebration enough, but the new limited-edition azure blue Overseas Perpetual Calendar Ultra-Thin is a limited edition that honors the first generation of the collection. Below is a picture of the current third generation and the 1996 first generation, itself a successor of sorts to the 222 in 1977 and the 1975 Chronomètre Royal before it. Yes, Vacheron has done a blue version of this watch before—and has released a few other colors recently, including a bold red—but now the same 41.5mm by 8.1mm white gold case gets a more muted, less saturated azure blue soleil and lacquer treatment, with white and light blue printed text and applied indices with Super-LumiNova. The movement is the same Caliber 1120 QP/1 automatic movement that is only 4.05 mm thick. Yes, other brands are slowly introducing perpetual calendars with a crown-adjustment system, but while this still uses caseband pushers, the benefit is a watch that measures 1.5mm thinner than the similarly wide Audemars Piguet Royal Oak. The watch runs at a slightly slower 2.75 Hz and has only 40 hours of power reserve, but again, at the thin profile you get, the wearability should more than make up for any small downsides. Another huge benefit i...

In-Depth: IWC’s Pioneering ProSet Perpetual Calendar
IWC’s history is dotted with landmark innovations such as Albert Pellaton’s pawl winding system, Kurt Klaus’ famous perpetual calendar, and Richard Habring’s split-seconds chronograph module; the ProSet perpetual calendar system continues this legacy. This bidirectional perpetual calendar module made its debut earlier this year at Watches & Wonders inside the Big Pilot’s Watch Perpetual Calendar ProSet, and remains true to IWC’s identity as an engineer’s manufacture. A smaller Big Pilot QP The Big Pilot ProSet unveiled at Watches & Wonders blends the manufacture’s latest engineering feat with the beloved styling of the pilot’s watch. The ProSet system is currently only available inside the 42 mm Big Pilot. Powered by a downsized base calibre, the 42 mm ProSet is the first Big Pilot under 46 mm to include a perpetual calendar. IWC has a tweaked and scaled down the its signature Kurt Klaus module in the past for the 42 mm Portugieser and some Portofinos, but somehow it never made into the reduced Big Pilot collection. Unfortunately, these smaller watches lacked the now-iconic digital year display, and instead featured a subtler (but more forgettable) leap cycle aperture. The ProSet brings back the four-digit year display, making this watch almost indistinguishable from the original 46 mm version. Apart from some styling choices, the main difference in the displays is the lack of a power reserve indicator. The cal. 82665 inside is powered by a single mains...

Hands On: A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar “Lumen”
A. Lange & Söhne’s flagship launch for the year, so far, is the Lange 1 Tourbillon Perpetual Calendar “Lumen”. It follows a familiar template, applying the desirable “Lumen” treatment to a complicated, top-of-the-line model. But unlike earlier Lumen editions, the Lange 1 Tourbillon Perpetual Calendar is more than a mere cosmetic makeover. The unique calendar display requires a more complex dial construction, and the movement has been reworked for visual impact. Even though the concept is predictable – and predictably pricey – the Lange 1 Tourbillon Perpetual Calendar “Lumen” is unexpectedly appealing. Initial thoughts This is stating the obvious, but the Lange 1 Tourbillon Perpetual Calendar “Lumen” is clearly the most appealing iteration of the most complicated Lange 1. Visually it is more striking in both light and darkness, with the new look also adding to the intricacy of the dial construction. And because Lange doesn’t do things in half measures when it comes to movements, the L225.1 inside this has been reworked by some margin to solve one of the shortcomings of the original model, a tourbillon that was barely visible. The original Lange 1 Tourbillon Perpetual Calendar was and still is the most complicated version of Lange’s iconic watch design. All perpetual calendar indicators were cleverly incorporated in the Lange 1’s distinctive yet sensible layout. Add to that a tourbillon visible only on the back meant there was a lot going on ins...

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...

Introducing: The Vacheron Constantin Traditionelle Twin Beat Perpetual Calendar Is Back
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...

There’s a rapid surge happening in watchmaking right now.
