Citizen Introduces the Promaster Diver “Fujitsubo” in DLC Titanium

Citizen’s flagship mechanical dive watch gets an upgrade with the Promaster Mechanical Diver 200m “Fujitsubo”. The new “Fujitsubo” diver features a gradient-finish grey dial, but its standout feature is the case and bracelet in the brand’s proprietary hardened titanium alloy coated with diamond-like carbon (DLC). Initial thoughts Sometimes underestimated, Citizen’s dive watches don’t garner as much attention as those of its competitor Seiko, primarily due to the scarcity of mechanical dive in Citizen’s lineup. Most of Citizen’s dive watches are solar-powered or quartz. Nevertheless, the Japanese watchmaker has recently taken significant steps towards boosting its mechanical offerings, particularly with the introduction of the oversized and modern Promaster 200 m diver. The “Fujitsubo”, on the other hand, takes inspiration from the Challenge Diver of 1977, explaining its vintage styling. But this latest iteration exudes a more contemporary feel owing to the gradient grey dial and the DLC coating on the case and bracelet. The resulting shades-of-grey livery makes this stand apart from its predecessor, which was essentially a like-for-like remake.  Priced at US$1,195, the “Fujitsubo” DLC is a bit more expensive than the standard titanium model. Nonetheless, it justifies the higher price tag with improved aesthetics and the superior durability offered by the DLC coating. That said, it would have been even more appealing with the option of a rubber ...

Citizen Promaster Tsuno Chrono Back Jul 6, 2023

Celebrating 50 Years of Being Fashionably On Time with the Citizen Promaster Tsuno Chrono

Back in January of 1973, Citizen, a pioneering Japanese watchmaking house, released a unique riff on a watch that they’d launched only a few months earlier. The watch was their very first mechanical chronograph. This version had the chronograph pushers situated at the top of the case, rather than on the side, in what’s affectionately referred to as a bullhead configuration called the Citizen Challenge Timer. Fans would soon nickname the “Tsuno Chrono” and its instantly recognizable 70s tones and panda dial layout would make this particular variant a legend. Fast forward to August 1, 2019, when a young watch journalist, and co-founder of a particular watch enthusiast publication, would rush home from a movie theater to research a timepiece he’d seen on screen. Zach Weiss had just finished viewing Quentin Tarantino’s critically acclaimed ninth film, Once Upon a Time … In Hollywood. Here’s an excerpt from the article he penned and published immediately thereafter. The film went on to be nominated for a total of ten Academy Awards at the 2020 Oscars and won two including Best Supporting Actor for Brad Pitt, which further cemented his role and this watch into absolute icon status. Despite a blatant continuity error, it’s clear that this was not a miscasting. It was still the right watch, on the right wrist, in the right role, at the right time. Now, 50 years later from the introduction of the original Tsuno Chrono, Citizen has reimagined the concept, form fact...

Girard-Perregaux Constant Escapement? Jun 27, 2023

Insight: What’s Next for the Girard-Perregaux Constant Escapement?

In an era of modern and accessible digital technology, the utilitarian role of mechanical timekeepers has inevitably dwindled. Yet, it is still pursued as a luxury of an artform – either of the highest finishing by hand that can’t be performed by machines, or the research and development in making a mechanical timepiece – in particular wristwatches – as accurate as possible.  One of these horological pursuits, to preserve the accuracy of mechanical wristwatches, is the supply of a constant force to the escapement. To isolate the varying torque as a mainspring gradually unwinds, some haute horlogerie watches today incorporate either a fusée-and-chain or a remontoir, which supplies a steady torque to the escapement for stable timekeeping.  However, there is one particularly novel take on constant force released by Girard-Perregaux, in the form of a proprietary escapement. First unveiled as a prototype in SIHH 2008, the Girard-Perregaux Constant Escapement has a patented, double escape wheel system that is designed from the ground up to inherently have a built-in constant force system, thus eliminating the need of a remontoir or a fusée-and-chain.   Despite being first created 15 years ago, Girard-Perregaux (GP) is still further developing the escapement today, with a new set of patented improvements publicly available – strongly hinting at a revamped model in the near future. These patents make it worth a deep dive into the original Constant Escapement (CE) fr...

24 Perpetual Calendar Watches from The World's Leading Luxury Watchmak

The most sophisticated type of calendar watch, a perpetual calendar is endowed with a mechanical “memory” that enables it to record and display the time, day, date, month, and often the moon-phase, accurately for many years. The complex movement in a perpetual calendar compensates for the length of every month, including February in both leap years and non-leap-years, meaning that it should not need adjusting until the year 2100, which is the next annum in which the Gregorian calendar’s leap-year cycle is disrupted (it will be the first year since 1900 that is exactly divisible by 100 but not by 400, and thus not a leap year). As you'd expect, perpetual calendar watches (called "quantième perpétuel" in French) are extremely complicated in their mechanics and design, representing one of the highest pinnacles of high horology and priced accordingly. Throughout the modern wristwatch industry, only a relative handful of brands have mastered the art of the perpetual calendar: we showcase some of them, and their most impressive perpetual calendar timepieces, here.  A. Lange & Söhne Lange 1 Perpetual Calendar Introduced in 2021, the Lange 1 Perpetual Calendar adopts the new approach taken to perpetual calendar design that the Saxon maison established in 2012 with the Lange 1 Tourbillon Perpetual Calendar. In typical Lange fashion, the technical approach taken is complex in the service of user-friendly practicality. Its in-house, self-winding movement, Caliber L021.3, ...

Louis Vuitton Introduces the Tambour Street Diver Chronograph

Two years ago, Louis Vuitton unveiled the Tambour Street Diver, a livelier iteration of its longstanding Tambour dive watch. Now the brand debuts the Tambour Street Diver Chronograph, adding further a stopwatch to the nautical-inspired aesthetic. Together, the two Street Divers now form the entry-level of the brand’s mechanical watch offerings, which progress upwards into seven-figure, minute-repeater-with-automaton territory. Initial thoughts The new chronograph is a natural progression from its predecessor, retaining the elements of a traditional dive watch, including a less-common inner rotating bezel, while incorporating Louis Vuitton’s bold and modern styling, including the tall, drum-shaped case. The design is as much “street” as it is “diver”, and very much in keeping with the brand’s aesthetic. Both the case and dial are executed well, although the two-tone case might not be to everyone’s taste. Enthusiasts, however, will note the ETA movement inside. The movement is reliable and robust, though the US$11,105 price tag deserves a more interesting calibre. That said, given Louis Vuitton’s well-funded ambitions in watchmaking, it is a certainty that the brand will soon roll out in-house calibres in all price segments of its catalogue. Nautically inspired The new chronograph available in two variations: Skyline Blue (blue with metallic sun-ray finish) and Neon Black (matte black), each matched with a case colour in the same colour. Both have the same ...

Grand Seiko Unveils the Tentagraph, a New Sports Chronograph with a Three Day Power Reserve and High Frequency Movement

This year’s marquee release from Grand Seiko is the all new Tentagraph, an imposing and technically impressive chronograph that makes use of a new high beat caliber and a case shape derived from previous watches in the Evolution 9 Collection. It’s kind of hard to believe, but up until now, Grand Seiko didn’t have a purely mechanical chronograph in their collection. Spring Drive has ruled the day if you need a watch for timing laps, steaks, or anything else, but that changes this year.  With the Tentagraph, which carries reference SLGC001, Grand Seiko introduces a new movement, Caliber 9SC5. This movement is notable for its shared architecture and essential technical features with the next-gen 9SA5, the double-impulse escapement caliber introduced by the brand a few years ago. We’ve seen that basic time and date caliber adopted in a variety of excellent watches in the relatively short time it’s been in production, but this is where the fun really starts: we now have a new caliber derived from the 9SA5, which of course would lead anyone following the brand to think that a) we’ll see more chronographs coming from Grand Seiko within the Evolution 9 Collection and b) we’re likely to see more complications. The 9SA5 now takes its place as a halo caliber, with many possibilities ahead when it comes to variations large and small.  Like the 9SA5, the 9SC5 beats ten times per second and is powered by two barrels giving it a three day power reserve. That’s with the ...

How The World's Most Accurate Watches Are Made

Nearly every advance in watchmaking technology has been in the service of increased utility and functionality - even inventions that we now consider entirely luxurious affectations. The minute repeater, for example, was invented so a watch wearer could audibly check the time in the dark in the days before luminous treatment on dials. Even the tourbillon began its existence as a device for enhancing timekeeping accuracy, countering the effects of gravity on a pocketwatch’s movement. Thus it should come as no surprise that as the world entered the electronic era in the mid-20th century, watchmakers would attempt to harness the new technologies to improve the precision - and hence the desirability - of their products. Read on as we trace the evolution of timekeeping technology all the way up through today’s most accurate watches.  Birth of the Chronometer Not long after the tracking of time migrated from giant clocks in the town square to portable devices carried in waistcoat pockets, and eventually worn on wrists (click here for a brief history of watches), the need for a standard of dependable accuracy in these mechanical timekeepers became evident. Hence the establishment of standards for which a timepiece could be deemed a "chronometer." The classical definition of a chronometer goes all the way back to the golden age of seafaring exploration in the 18th Century, when ships required the use of a highly accurate onboard clock that enabled their navigators to det...

Furlan Marri Adds a Trio of Sector Dial Three-Handers to their Permanent Collection

You might recall that when Blake Buettner brought us news of Furlan Marri’s very first fully mechanical watch (after the success of their popular meca-quartz chronograph that we still can’t believe ever sold for under $500 during the crowdfunding campaign) he mentioned that the limited production black dialed three hander he had in for review would be followed up by a trio of models in the brand’s permanent collection. That was in June of 2022, and at long last, those watches are here. These three new references use the same platform as the previously issued “Black Sector” 2116-A, but in an array of colors that give the watch a new impact.  The new dials, Salmon Sector, Grey Sector, and White Sector, have been given reference numbers 2154-A, 2161-A, and 2145-A, respectively. While the Grey Sector has what Furlan Marri refers to as a double printed dial, the white and salmon versions both have applied baton hour markers, and all references have a fine texture applied to the dial. The Breguet style numerals at the cardinal positions have become a hallmark of sorts for Furlan Marri, and those remain on all three variants. Dial text is minimal (just the Furlan Marri wordmark and the reference number discreetly out of the way between 4 and 5), the sector layout identical to the black version from last year. Fans of aggressive symmetry will be quite pleased, I think.  An area where Furlan Marri has excelled since the launch of that first chronograph back in 2021 is i...

Seiko Introduces Prospex 1968 Diver’s GMT SJX Watches

Seiko Introduces Prospex 1968 Diver’s GMT

Responsible for some of the most reliable and well-priced diver watches on the market, Seiko is synonymous with the genre. The Japanese watchmaker continues to expand its dive watch offerings, but now with a second time zone complication. A “modern reinterpretation” of its Hi-Beat 300 m dive watch from 1968, the Prospex 1968 Diver’s GMT is the first mechanical dual-time zone dive watch in Seiko’s Prospex sports watch collection. The SPB383 Initial thoughts Arguably the collection offering the best value in Seiko’s line-up, Prospex is going slightly upscale with the second time zone movement, while maintaining its strong price-performance ratio. The standout among the new models is the SPB381 with its deep green dial. While the limited edition SPB385 with its textured, “ice blue” dial is undoubtedly fancier, the SPB381 is clean and functional but appealing with its palette. The SPB381 Though it is a two-time zone watch, the Diver’s GMT is still primarily a dive watch. So it retains the traditional elapsed time bezel and clever places the 24-hour scale on the flange around the dial. That said, the Diver’s GMT is more accurately a dual time zone watch with an independently adjustable 24-hour hand, rather than a true GMT that has an adjustable local-time hour hand (as found in pricier Grand Seiko models). This means a few extra steps when setting the time for a change in time zones, though it is a perfectly acceptable compromise considering the price. At U...

Insight: Daniels’ Co-Axial Escapement, an Evolution of the Fasoldt Chronometer

In the quest for precision chronometry in a mechanical watch, perhaps no other component is as crucial as the escapement – often consisting of an escape wheel and lever that engage with the oscillating organ. The history of watchmaking recounts many an attempt at inventing a better-performing escapement, with some attempts naturally more successful than others. By the 20th century, the watch industry had settled upon the Swiss lever escapement, which has proven itself to be a reasonably solid performer and crucially, one fit for mass production. However, in the latter decades of the century, one English watchmaker attempted to challenge the industry status quo. In 1974, George Daniels invented the “co-axial escapement”, a seemingly novel and practical escapement of his own design that was conceived as an functionally superior alternative to the Swiss lever escapement. Daniels’ invention fulfilled his ambition, at least in part, when it was sold to Omega and then successfully industrialised starting in 1999; today it is found in hundreds of thousands of movements that Omega produces each year. The latest iteration of the Omega Speedmaster Moonwatch is kitted out with the co-axial escapement With the merits of the co-axial escapement having been proven in part by its large-scale adoption, my aim here is not to examine its intrinsic qualities, but rather delve into its development. Specifically I will explore the fact that the co-axial escapement might not be an ent...

Up Close: Louis Vuitton Tambour Slim Vivienne Jump Hours

Louis Vuitton (LV) marked the 20th anniversary of its first mechanical watch last year (with an El Primero-powered chronograph). The brand has rapidly evolved its horological offerings over the two decades, going from largely basic, monogrammed watches to ambitious complications like the gothic Carpe Diem Minute Repeater with automaton.  A more whimsical example of LV’s progress in complications is the Tambour Slim Vivienne Jump Hours, a quirky interpretation of the jump hour complication that’s presented in a redesigned, svelte version of its signature drum-shaped case. Initial thoughts At the distance, the Vivienne Jump Hours looks like a run-of-the-mill character watch that’s slightly fancier than average. But upon closer inspection, it reveals a novel complication and an impressive degree of detail in the execution of the dial. The jump hour is mechanically conventional but presents as a double jumping indicator thanks to clever design. Its whimsical and unusual presentation typifies the spirit of LV. In fact, the complication is different enough that we hope it will make its way into more watches, especially timepieces for men. Given that the titular Vivienne character has a male counterpart named Gaston, it would make sense for the complication to make its way into a watch in a larger size.  The Tambour Slim Vivienne Jumping Hours “Casino” with a green skarn dial And I really dig the dials of the Vivienne Jump Hours, especially the dial in skarn, a re...

Piaget Goes Ultra-Thin for New Polo Perpetual Calendar

The trend toward ultra-thin highly complicated watches has reached a fever pitch in recent years, and there’s no sign of that trend slowing anytime soon. Piaget has been at the forefront of ultra-thin watches for many decades, most recently claiming the world’s thinnest mechanical watch with their Altiplano Ultimate Concept in 2020 (which was subsequently broken by Bulgari, and then Richard Mille). This year, they’re returning to the ultra-thin game with a new Polo Perpetual Calendar that measures a mere 8.56mm in thickness. This marks the first appearance of the perpetual calendar complication within the current generation of the Polo, and it should come as no surprise that it works rather well.  The Piaget Polo was redesigned in 2016 with a more refined presentation of their sports watch language. The round case features a slightly squared, TV shaped dial opening creating just enough tension to set it apart in a crowd. This was a notable departure from earlier Polo designs, which have never been shy about embracing their era. The newest Polo design feels timeless to my eye, but history will be the judge there. The design has shown flexibility, with the openworked Skeleton Automatic, and even on the very high end housing the brand’s ornate minute repeater in this Polo Emperador. The Polo Perpetual Calendar is the most complex Polo to date, and effectively uses the 42mm case to showcase their take on the QP. The information is presented in a clear and easy to unde...

De Bethune Introduces Custom Regulation Nov 14, 2022

De Bethune Introduces Custom Regulation with the Sensoriel

De Bethune’s latest invention aims to customise the regulation of a mechanical watch to suit the individual owner. Dubbed the Sensoriel Chronometry Project, it takes the form of a electronic wrist instrument that measures the wearer’s activities and environmental conditions over a two week period – gathering two million data points per hour according to the brand. With this voluminous quantity of data, De Bethune will then regulate a DB28GS Grand Bleu sports watch specifically for the particular owner, optimising timekeeping based on the wearer’s activities. [Updated to include response from Denis Flageollet.] Initial thoughts On paper the Sensoriel is interesting and impressive, but on reflection it raises several questions. For one, the two million data points recorded per hour – for a two-week period – results in an extraordinary amount of information on the wearer’s activities. Can any mechanical watch be regulated to a fine enough resolution that makes even a fraction of that data useful? My knowledge of watchmaking is certainly inexpert but I am sceptical. Mr Flageollet points out De Bethune utilises an algorithm to process the data and sieve out the “elements specific to the wearer, in a way to bring out a specific chronometric DNA for each wearer”, allowing the watch to be regulated according to a smaller number of data points. The second salient point is more philosophical. Historically the pursuit of chronometry meant good timekeeping regardless...

What are the Different Types of Watches? A Comprehensive Guide

To a newcomer, deciphering the world of timepieces can be an intimidating endeavor, and identifying the different types of watches presents a particular challenge. What distinguishes, say, a dive watch from a pilot watch, a quartz watch from a mechanical watch, a dual-time watch from a world timer? What are all those subdials and scales on the dial for? Do I need to change the date on my watch, and if so, how often? In this rundown of the various types of watches, we strive to answer the big questions (and/or link to another article that does).  Quartz vs. Mechanical vs. Automatic While watches vary widely in their styles, genres, and capabilities, they all fall into one of two major categories based on the type of movement inside them. Generally, with a few notable exceptions that we’ll touch upon, a watch is either “mechanical” or “quartz.” Mechanical watches further subdivide into two basic types: manually wound (or “hand-winding”), in which the user needs to periodically wind the watch via the crown to keep it working; and automatic (or “self-winding”), in which the movement’s mainspring is perpetually wound by an oscillating weight that swings with the natural motions of the wearer’s wrist. On the other hand, a quartz movement (as explained much more thoroughly in this article), replaces the mechanical movement’s traditional mainspring barrel with a small battery whose electrical charge passes via an integrated circuit into an oscillating tuni...
