Berneron Jumps Forward with the Quantième Annuel

One of the headline releases from Geneva Watch Days is, without question, the Berneron Quantième Annuel, a symmetrical annual calendar that brings the brand’s vision into sharper focus. Expensively made and cleverly designed inside and out, the Quantième Annuel is a showcase for founder Sylvain Berneron’s attention to detail. A limited run of 480 pieces in platinum, with production spaced evenly over the next decade, the Quantième Annuel is available in two dial configurations; whether the buyer opts for lacquered silver or piano black, the dial itself, along with much of the movement, is crafted from 18k gold. Initial thoughts I’ve written effusively about user-friendly complications in the past so it should come as no surprise that I like the Quantième Annuel’s legible display and intuitive interface. Visually, it’s a world apart from the oozy Mirage, but it exhibits a similar degree of intellectual sophistication and attention to detail. A jumping hour watch with an instantaneous annual calendar, the Quantième Annuel is distinguished by its oversized windows for the hour, day, and month, with a sector-style dial for the minutes and a concentric retrograde date display. The running seconds dial at six o’clock contains the fourth jumping window for the day/night indicator; a useful addition for any calendar watch. The watch is designed for easy legibility, with the time read top-to-bottom and the date read left-to-right. The sector dial for the minute han...

“Watches, Stories, and Gear” is a roundup of our favorite content, watch or otherwise, from around the internet. Here, we support other creators, explore interesting content that inspires us, and put a spotlight on causes we believe in. Oh, and any gear we happen to be digging on this week. We love gear. Lancaster Watch Weekend   Lancaster Watch Weekend is almost here, and it’s an event that you should absolutely have marked on your calendar if you’re a fan of American watchmaking, and watchmaking history more broadly. Lancaster, PA is home, of course, to the original Hamilton factory and company headquarters, and the small Pennsylvania city remains a haven for watch lovers even decades after the brand moved to Switzerland. That’s largely thanks to the work of the NAWCC, whose museum resides in nearby Columbia, and will be hosting guests and special presentations throughout the weekend. You can also check out an open house at RGM Watch Co.’s headquarters in Mt. Joy (about a half hour from Lancaster) and hit up events at Lancaster’s Hamilton boutique over the course of the weekend. Lancaster Watch Weekend will run from September 26-28, in and around Lancaster.

Dubai Watch Week Returns in November 2025

Now a decade old and an established event in the annual horological calendar, Dubai Watch Week (DWW) will take place November 19-23, 2025. Most notably, DWW will move to a new venue, a 200,000 sq ft space next to Dubai Mall, departing its longtime home of the Dubai International Financial Centre (DIFC). The 2025 event will host over 90 brands, ranging from giants like Rolex to micro-brands such as Studio Underd0g. The biggest names will have standalone spaces, including Rolex and Tudor, Audemars Piguet, Van Cleef & Arpels, and Chanel. DWW traditionally took place at DIFC, pictured above But independents will still have a prominent role in the event, since DWW got its start as an indie-centric event. The 2025 edition will give independent brands room to breathe with a dedicated space. Exhiitors include leading independents like Rexhep Rexhepi, Voutilainen, and Roger W. Smith. DWW takes place from November 19-23, 2025 in Burj Park, the landscaped area surrounding the Burj Khalifa and adjacent to Dubai Mall. Entry is free but registration is required.

Long considered the domain of delicate watches, grandes complications (in the more extensive use of the term, and not the traditional definition of the grande complication – repeater + chrono + calendar) have found their way into collections designed for adventure.

Debuted But Not Debated: The Green Cerachrom Dial In The Left-Handed White Gold Rolex GMT-Master II “Sprite”

It was the Land-Dweller that stole the limelight, and understandably so. After all, it’s not often that The Crown presents an entirely new collection with a groundbreaking movement innovation to boot. I did feel sorry for the other novelties, though. The pastel-tinted Oyster Perpetual watches were quite lovely, for instance, but they got trampled on […] Visit Debuted But Not Debated: The Green Cerachrom Dial In The Left-Handed White Gold Rolex GMT-Master II “Sprite” to read the full article.

Hands On: Patek Philippe Calatrava 8-Day Ref. 5328G SJX Watches
Patek Philippe Calatrava 8-Day Ref 5328G May 8, 2025

Hands On: Patek Philippe Calatrava 8-Day Ref. 5328G

One of several strong new releases from Patek Philippe this year, the Calatrava 8-Day Ref. 5328G is a simple day-date watch distinguished by an all-new manually wound, eight-day movement. Carrying on the contemporary aesthetic of the Calatrava ref. 5226G and Annual Calendar ref. 5326G, the new watch features a grained fumé dial and an 18k white gold case with a middle fully encircled with clous de Paris guilloche. The ref. 5238G is purposeful in its design, which gives it a casual, almost tool watch-like appearance that offers a pleasing contrast to its overtly luxurious case and movement. Initial thoughts Patek Philippe put on a good show at Watches & Wonders this year, and the ref. 5328G might be my favourite of the bunch. The watch has a strong presence thanks to its hobnail case band and instrument-like dial, but it really stands out when you turn the watch over and see the vintage-inspired bridge architecture. Patek Philippe is usually pretty utilitarian when it comes to movement design, so it’s nice to see them let their hair down and have some fun with this one. The fumé navy blue dial features an asphalt-like texture first seen on the ref. 5226G introduced in 2022. The ref. 5328G also benefits from this predecessor’s lumed syringe hands and clean Arabic numerals, which give it the earnest, purposeful feel of a deck watch. Patek Philippe is not known for its typographical expertise, but here even the numerals on the date ring strike the right tone. The watch f...

Rolex Oysterquartz: The Complete Guide

When Rolex introduced its Oyster Perpetual Land-Dweller watch at Watches & Wonders 2025, some longtime fans of the brand experienced a bit of déja vu for a Rolex watch - and a Rolex era - that have been largely consigned to the mists of history. Why? Because the Land-Dweller's angular case and integrated-bracelet design reminded many enthusiasts of the Oysterquartz models introduced during the early heyday of quartz watches in the 1970s. That's correct: once upon a time, Rolex, one of the undisputed champions of luxury watches with mechanical movements, jumped on board the Quartz Revolution bandwagon and not only produced its own in-house quartz calibers but marketed the watches that housed them as the pinnacle of the Crown's timepiece portfolio at the time. Here is everything you need to know about the Rolex Oysterquartz and its quirky but significant place in horological history.  Rolex Oysterquartz: The Early Days Of Electric Watches The wristwatch industry, like any other industry, is uber-competitive and every watchmaker wants to be the first to market with The Next Big Thing. In the 1950s and into the ‘60s, that Next Big Thing was a watch that could be powered by electricity. American companies like Hamilton, with the Ventura, and Bulova, with the Accutron, were among the pioneers, even though the movements that resulted from these early efforts proved to have difficulty maintaining reliability in mass production. The Japanese, particularly Seiko, took a diff...

First Impressions of the New A. Lange & Söhne Novelties Worn & Wound

First Impressions of the New A. Lange & Söhne Novelties

A. Lange & Söhne never does half-measures, especially at Watches & Wonders. For 2025, they announced three new models, but a total of four watches: the Saxonia Minute Repeater Perpetual, the Honey Gold Odysseus, and the 1815 in 34mm in rose and white gold. So, one super complicated piece with a ton of features. One rare piece in an exceptional presentation. And two sublimely proportioned everyday watches (in ALS terms). While all were exceptional, the latter of the three left the biggest impression, despite being the smallest in stature.  With a name like Minute Repeater Perpetual, there’s not much mystery about what this watch does, but in true Lange fashion, it’s the elegance with which it does it that’s so special. And, naturally, we have to start with movement. The new caliber L122.2 consists of 640 parts and is meticulously finished to the standards one expects from Lange. In somewhat of a departure from their norm, the untreated Glashütte ¾ plate features a frosted finish instead of Glashütte ribbing. Though the result might appear more straightforward, we were told it makes assembly more complicated, and the resulting even surface puts more attention on the governor, black polished hammers, and encircling gongs, not to mention the free-hand engraved balance cock. It does not just look impressive, however, as there are some clever mechanical tricks at play, too, namely regarding the repeater. The typical sequence of chimes includes first single chimes per ...

Introducing A New Way Of Looking At The Date: The Krayon Anyday Is The World’s First Mechanical Agenda Watch

In 2018, Krayon, the brand founded by independent watchmaker Rémi Maillat, won the Innovation Prize at the Grand Prix d’Horlogerie de Genève (GPHG) with its Everywhere watch. Four years later, Krayon bagged another GPHG award. That time, the complicated Anywhere won first prize in the Calendar and Astronomy category.

Krayon’s Anyday is a Day-Date “Mechanical Planner” SJX Watches
Krayon Mar 13, 2025

Krayon’s Anyday is a Day-Date “Mechanical Planner”

Krayon continues with its focus on calendar-related complications with the Anyday. Coming after the Anywhere and Everywhere, the Anyday is not an astronomical complication, but rather a seemingly-simple watch, albeit one with a twist. The Anyday is more than just a basic calendar watch as it offers an intuitive way of visualising the days of a month. Krayon describes the Anyday as a “mechanical planner”, with its display giving a complete view of the current month’s layout in terms of dates and weekends via a colour-coded date display. Initial thoughts Since the Anyday shows the days of the week over the course of a month, the utility of the concept is clear. It allows the wearer to tell if a certain future date will be a Monday or Tuesday, for example. Design wise, the Anyday also continues with Krayon’s established aesthetic, resulting in a recognisable house style. The quality of execution also lives up to the earlier Krayon timepieces. The movement is carefully finished and bears the hallmarks now requisite in high-end independent watchmaking, while the dial is clean and conveys the Krayon aesthetic well. The weekday planning function is useful and conceptually interesting, but it is little disappointing in mechanical terms, especially in comparison to the Anywhere and Everywhere, which are true complication powerhouses. An annual calendar or another basic calendar complication would have made the proposition a little more appealing. That is not to say the Anyd...

Independent Watchmaking on Show in London SJX Watches
Louis Vuitton Watch Prize Raúl Pagès Mar 11, 2025

Independent Watchmaking on Show in London

Phillips Perpetual will shortly open a three-day exhibition dedicated to independent watchmaking at its London showroom. Independent Spirit will comprise five notable watchmakers whose work encapsulate the diversity of the genre: Konstantin Chaykin, Raúl Pagès, Theo Auffret, Charles Frodsham, and David Candaux. The watch boutique arm of the eponymous auctioneer, Phillips Perpetual conceived the exhibition as a small-scale event that will allow personal interaction with each of the watchmakers, or in the case of the long-departed Charles Frodsham, the brand’s representatives. The exhibition will be a rare opportunity to meet some of the leading lights of independent watchmaking. Amongst them is Raúl Pagès, a true artisanal watchmaker in the traditional sense. Mr Pages will have on hand examples of the Soberly Onyx, his inaugural watch, and the RP1 Régulateur à détente that won him the Louis Vuitton Watch Prize. Raúl Pagès While all of the other watchmakers at the exhibition are relatively young, Charles Frodsham is a continuously-operating, centuries-old brand – proof that independent watchmaking innovation can come from unexpected places.

Honest question: why do people like the Sky-Dweller? Is it because the travel watch with the Saros annual calendar and Ring Command is a complicated piece of watchmaking?

Frederique Constant Refines the Worldtimer Manufacture SJX Watches
Frederique Constant Refines Feb 13, 2025

Frederique Constant Refines the Worldtimer Manufacture

Known for its value-oriented timepieces, Frederique Constant partnered Swiss crowdfunding specialist Watch Angels to reimagine the Worldtimer Manufacture. Now in a 40 mm format with a cleaner aesthetic, the limited-edition of 718 pieces will only be available for purchase through Watch Angels’ online shop via a pre-order. Initial thoughts Frederique Constant has some interesting and accessible models, ranging from perpetual calendars to tourbillons and even a flexural pivot monolithic oscillator. The Geneva-based brand is mostly a player in the under-CHF5,000 segment, with a focus on in-house engineering. This latest iteration of the Worldtimer Manufacture is a good example of Frederique Constant’s approach to blending appealing designs with in-house mechanics, while keeping the price accessible. This new release builds on the successful Classic Worldtimer Manufacture collection, but with a streamlined design and reduced case size. It looks like Watch Angels took the lead with the design, opting for a clean layout, strong blue hues and sharp case lines. In contrast to the original that has a fussy design with a world map dial, the new version is functional but still elegantly detailed. The reduced case size, cleaner dial, and sharp finishing make this a compelling worldtime complication timepiece. Furthermore, the limited edition costs virtually the same as the regular production model, making this collaboration very appealing. More broadly, the partnership between Fr...

TAG Heuer Debuts a Pair of Purple Carrera Chronographs, Including a Glassbox Tourbillon, for LVMH Watch Week

LVMH Watch Week has quickly become a yearly staple on the release calendar for watch enthusiasts since its inaugural year in 2020. A mix of novelties and staple collections have graced the headlines acting as a special kickoff to the new year and this year is no different. What immediately caught my eye though was a pair of Carrera Chronographs sporting a new-to-the-model dial color. Enter the TAG Heuer Carrera Chronograph and Tourbillon in purple. Equipped with a smoky black-to-purple gradient backdrop, the Glassbox design family continues to grow. Following the release of the TAG Heuer Monaco Purple Dial in 2022, I had assumed that we would see this color trend carried throughout the rest of the catalog. With that model being discontinued and somewhat hard to come by, it is not surprising that the tourbillon model was also slapped with the LE designation. What is a surprise though is that the standard Carrera Chronograph is not limited and is entering standard production. This will hopefully give those lusting to add an excellent pop of purple into their collection the opportunity as these begin to trickle out to authorized retailers, though I do suspect that they will still be a bit hard to come by immediately. By far the standout feature of the watch is its appearance. Appearing almost black in medium to low light conditions, the purple breaks through in direct light playing with its sunray-brushed surface. The effect lends dimensionality and versatility to the design ...
