Oddly enough, one of the year’s highlights is a quartz watch that costs almost US$17,000 – but it is the most accurate wristwatch ever, rated to run within a second a year and probably less in practice. The Citizen Caliber 0100 slightly plain but the technology within is mighty impressive. Also impressive is the thought and effort put into developing the movement; that is extremely Japanese. It feels slightly anachronistic given the alternatives that can sync with GPS or radio waves and keep just as good time, but it is still mighty impressive. The top of the line model is in 18k white gold, explaining the price tag, but fortunately there’s a titanium model with the same movement for half the price. The Citizen Caliber 0100 The 0100S movement Sporty-ish and value For almost exactly the same price, the Bulgari Octo Finissimo Chronograph scores high in terms of value for money. It’s an ultra-thin – really, really thin – chronograph with a second time zone function that continues Bulgari’s streak of extra-flat Octo watches. Though the design is thoroughly modern, its slimness and proportions give it a graceful air. But at 42mm the case is verges on looking like a biscuit because it is flat and wide. And the thinness of the movement, combined with a rather small balance wheel, inevitably invite questions about its robustness.

Nineteen-sixty nine was a watershed year in watchmaking – the culmination of the race for the world’s first automatic chronograph. It was a three-way contest between two Swiss watchmakers and one from Japan. Both Swiss movements – the Zenith El Primero and the Heuer-Breitling-Buren-Dubois-Depraz Caliber 11 – have enjoyed a following to this day, but the third – the Seiko 6139 Speedtimer – remains relatively obscure as it went out of production in 1979. The 6139 was a single-register chronograph with a 30-minute totaliser at six o’clock and a quickset day-date display. Crucially, it had a column wheel and vertical clutch. And an even lesser known fact is that Seiko produced its first chronograph – the “Crown” with a column-wheel and mono-pusher – just five years before, in 1964 to coincide with that year’s Tokyo Olympic Games. In short, the 1960s were a major decade for Seiko in terms of chronographs. The Seiko “Crown” chronograph of 1964 with its characteristic black plastic bezel Hence, to mark the 50th anniversary of its first automatic chronograph, as well as the 55th anniversary of its first chronograph, Seiko has unveiled a pair of limited editions, both chronographs, naturally. The two editions are each limited to 1000 pieces and powered by the same calibre, the in-house cal. 8R48 that was introduced in 2014. The first and the more modern looking of the two, is the Prospex 50th Anniversary Automatic Chronograph ref. SRQ029. I...

Continuing with our series focused on the mechanical chronograph – we already explained the vertical and horizontal chronograph clutches, along with the advantages and shortcomings of each – we now turn to another vital component but rarely discussed: the chronograph reset mechanism. While the clutch enables energy transmission between the base movement and chronograph, it plays no role in returning the chronograph indicators to a zeroed position. This is accomplished by an altogether separate mechanism that is synchronised with the clutch action but functions independently. The reset mechanism indexes all the chronograph indicators (hours, minutes, and seconds) back to the zero position, and keeping them securely in place until the chronograph is started once again. Any reset mechanism generally comprises of two main components: a heart cam and reset hammer. The two interact based on clever geometry and illustrates mathematics is often the underlying basis of watchmaking, or more specifically, movement construction. The chronograph works of a Breitling B01 movement, with the reset heart cams (12, 13, and 17) in purple. Image – Breitling patent The heart cam Named after its distinctive outline, the heart cam is a seemingly simple component that is in fact the product of some ingenious engineering. While the cam has a turning axis and is a rotational system – in other words, it revolves on a fixed axis – a clear analogy can be made with linear systems. In order to...

The vertical clutch has become the de facto standard in modern chronograph movements thanks to its mechanical and practical benefits. The widespread and varied use of the vertical clutch is illustrated by the many recent movements that employ the mechanism, ranging from the Rolex Cosmograph Daytona to the Breitling B01 to the MB&F; LM Sequential Evo. The proliferation of the vertical clutch is easily explained by its merits. Having explained the construction of a vertical clutch, we now turn to its advantages over the traditional horizontal clutch (or lateral coupling). Figure 1: A simplified cross section of a vertical clutch A vertical clutch serves to transfer energy from the going train of the movement to the chronograph going train, accomplishing this via a vertical motion. Figure 1 illustrates its key parts: a flywheel (yellow) geared to (or even part of) the going train; a cone (grey) that is linked to the chronograph seconds mobile, and vertically tensioned by a spring (red); a pair of pincers (blue) that engage with the cone, lifting or lowering the cone. When the cone is raised and engaged with flywheel, the chronograph starts running, and when the cone drops and disengages, the chronograph stops. One of the most apparent advantage of the vertical clutch is the low kinetic friction generated during coupling and uncoupling of the chronograph, as friction is produced only by the sliding motion of the pincers and the vertical motion of the cone. The Rolex Cosmogra...

Snob is a loaded, and sometimes divisive word in horology. Being called a snob, or calling someone a snob, is a quick way to draw blood by attacking someone’s particular approach to enthusiasm. As an enthusiast who cherishes the community aspect of this hobby, I’ve always been proud that my foundation in this hobby was built on the absence of snobbery. Or so I thought. I’m a frugal guy, and enthusiasm on a budget is a common theme in most of my articles. A keen eye for value shaped my early days in the hobby- an approach I haven’t managed to shake. For years, I assumed that embracing watches in all price brackets was enough to rid myself of any snobbery. But the more I “learned” about watches, the more I noticed snobbery seeping into my opinions, and in some cases stopping me from experiencing some truly awesome watches. I’d fawn over the latest Lorier release, only to question how a Hesalite crystal would hold up to an active lifestyle. Or I’d opt not to experience a 5 ATM field watch that I truly liked, instead compromising for 10 and 20 ATM alternatives. A quartz crystal, a small part of which is bound for a Grand Seiko 9F caliber I’ve since gone through an un-learning process thanks to a handful of watches that challenged what I thought I knew and allowed me to expand my horological horizons by kicking some snobby tendencies.

In 2019 Roue introduced their TPS line chronographs, which are inspired by the Porsche 910 that won the Nürburgring 1000-kilometer race in 1967. These watches feature both Tachymeter and Pulsometer scales surrounding the dial. Just in case you need to check your pulse, while at the same time measuring your speed. For 2023, Roue has come up with two more versions of their popular TPS line. Following in the footsteps of the previous five, we have the aptly named Six (with white dial), as well as the Seven (with a graphite/grey dial). Both feature tone on tone subdials with multi-color accents for a look that is inherently cohesive but still visually interesting. You would think two timing scales would make for a cluttered dial. In this case, you would be wrong. The tachymeter scale begins where the pulsometer ends, neither overlapping the other. It is remarkably clean and easy to read. This clarity is further enhanced by the lack of any text on the dial, apart from the brand name. Powering these chronographs is the Seiko caliber SII VK63, which is a Mecha-Quartz movement. For those that need a refresher, these movements blend quartz timing precision and mechanical chronograph technology. This allows for the tactile pleasure of that satisfying snap when activating the chronograph, along with the second-hand sweep we enthusiasts so enjoy. Aside from these 2 great characteristics, the biggest benefit of using this movement is its size and low cost. All TPS watches featur...

Having explored the Citizen Caliber 0200 last week, we now focus on arguably the most important aspect of the watch – the cal 0200 within. An important achievement for Citizen, the cal. 0200 is the brand’s first high-end automatic movement. The fact that the watch was named after its movement indicates its significance, and also the fact that the watch was constructed around the movement, rather than vice versa. The Caliber 0200 wristwatch is high quality, particularly in the finishing of its case and bracelet. That’s all the more impressive given its US$6,000 price tag, which leaves the best of class in its price segment in terms of finishing and quality. But the Caliber 0200’s merits are all encompassing – its movement is as accomplished as the external components. The cal. 0200 is an all-new, in-house automatic with with the features expected of a modern movement, and a little bit more. Beyond its intrinsic qualities, it is also notable for being a fusion of Japanese and Swiss watchmaking: its development, production, and assembly is done by Citizen in Japan, but with a key contribution from Swiss movement maker La Joux-Perret, which makes the base plate and bridges, and helped to refine the movement decoration. The rest of the movement – from development and construction to finishing and assembly – is done by Citizen at its headquarters in Tokyo. In fact, Citizen set up a specialised workshop, the Mechanical Watch Elements Development Department (or ME...

Citizen is one of the world’s biggest watchmakers, with its timepiece division generating about US$1 billion in sales each year – an output of several hundred million watches and movements annually. That vast manufacturing expertise means Citizen knows how to produce a fine mechanical movement. Now Citizen has finally accomplished it, and installed the movement inside a brilliant new watch. Launched earlier this month, The Citizen Caliber 0200 is equipped with the brand’s first mechanical movement developed from scratch as a high-end calibre (“The Citizen” is the name of the collection, while Caliber 0200 refers to movement as well as this specific model). Although the brand did launch a version of The Citizen with an automatic movement in 2010, the new Caliber 0200 is radically different, and tremendously superior. While the highlight is the new Caliber 0200, the entire watch is executed extremely well. The case and bracelet are outstanding, fabricated and finished so well there is nothing else that comes close in the same price segment. The quality of the watch was apparent in the press photos, which made me want to see it in the metal. I got my hands on a prototype for a couple of days earlier this month, an experience that left me substantially impressed. [Editor’s note: The watch pictured is a prototype, so it does contain a handful of hard-to-spot imperfections.] Initial thoughts On paper, the Caliber 0200 might seem uninteresting, being yet another sp...

The flagship watch of Breitling’s best-known watch, the Navitimer B19 Perpetual Calendar Chronograph is now more affordable. The latest iteration with an “ice blue” dial retains the specs of the pink gold 140th anniversary edition launched last year, but trades precious metal for steel. Unlike last year’s limited edition, the new steel model is regular production and is priced under US$30,000, over Breitling’s traditional sweet spot on the price spectrum but still half the retail of the anniversary edition. Breitling Navitimer B19 Chronograph 43 Perpetual Calendar_Ref. PB1920251C1P1_RGB Initial thoughts The new Navitimer B19 keeps it affordable, relatively speaking, by combining Breitling’s excellent in-house B01 movement with the tried-and-tested Dubois Depraz perpetual calendar module. The resulting watch is thick at almost 15 mm high, but combines several complications in Breitling’s iconic slide-rule pilot’s chronograph. While the watch is pricier than most of Breitling’s offerings, it is one of the few perpetual calendar chronographs in this price range. Most of such watches tend to be a lot more expensive, although Austrian independent watchmaker Habring² offers similar for less in keeping with its focus on affordable complications. Value proposition The new B19 retains the same basic specs as its precious metal counterpart. The stainless steel case measures 43 mm in diameter and 14.94 mm in thickness. Water-resistant to 30 m, it features the Navit...

Some things are worth the wait. Though the Tudor Black Bay 58 GMT will likely get the most press from the brand’s releases at this year’s Watches & Wonders event, the release of a stripped-down, monochromatic, black and silver, 41mm Black Bay is no less significant. Why? Well, it’s the most obvious colorway for a dive watch, which means it’s bound to be a classic. First launched in 2012, the 41mm Black Bay (just called “Black Bay”) is the watch that reestablished Tudor after some time in horological purgatory. Perfectly timed to ride the wave of vintage-inspired aesthetics that dominated for the decade hence, it showed that Tudor unliked their sister brand, Rolex, was willing to be a bit trendier and fun. Originally powered by ETA movements, it was the first to receive Tudor’s in-house caliber in 2016 and then underwent a third iteration in 2023 when it received the upgraded Master Chronometer certification (and technically a new caliber), as well as a slight redesign in the form of an updated handset, crown, and profile. With the introduction of the Black Bay 58, GMT, and 54 models, new versions of the Black Bay slowed down. Several different colors have been available, from the original burgundy bezel to a steel bezel with date to two-tone models. Yet, despite its tenure, the most obvious model never existed. The model most dive watches come in as a given: simple black-black bezel, black dial, white lume, white or silver markers. No gilt, no red, no fuss....

One of the watches synonymous with the pioneer era of spaceflight is the Breitling Cosmonaute, which was worn by Scott Carpenter on the 1962 Mercury-Atlas 7 mission, making him the second American to orbit the Earth and the Cosmonaute the first Swiss-made wristwatch to make it into space. The Cosmonaute has been part of the Breitling catalogue in various forms in the decades since, but now for the 60th anniversary of Carpenter’s journey to space on board the Aurora 7 spacecraft, Breitling has unveiled a remake, the Navitimer B02 Chronograph 41 Cosmonaute Limited Edition. The 362-piece edition is faithful to the original in terms of design, but upgraded with the in-house Caliber B02 and a bit of luxe in the form of a platinum bezel. A page from the 1964 Breitling catalogue showing the Navitimer-Cosmonaute ref. 809, the same model worn by Carpenter in space Initial thoughts I’ve always liked the distinctive aesthetic of the Navitimer – it is actually an aviation instrument – and the Cosmonaute is essentially a more complex version of the same thing, making it even more of an instrument. Granted all of that functionality has very limited use in the modern world, but it is still an appealing watch that possesses significant history. That in turn makes the Cosmonaute remake an appealing watch, especially since Breitling did a good job reproducing the original. The diameter remains the same but the modern-day version is necessarily thicker due to the in-house B02 movemen...

The Patek Philippe Star Caliber 2000 stands as one of the most technically ambitious pocket watches of the modern era. Launched to mark the turn of the millennium, it was the fourth most complicated watch in the world at its debut, but its true significance lies not in numbers, but in the ingenuity of its mechanisms, which redefined how grand complications could be conceived, engineered, and executed. An original complete set of four Star Caliber 2000 watches is being offered for sale by Sotheby’s at its first-ever watch auction in Abu Dhabi, which takes place in December. The first complete set to ever appear publicly, the sale will likely draw significant attention from collectors and institutions alike. The technical significance of the Star Caliber 2000 The Star Caliber 2000 was and is a remarkable achievement in watchmaking, but it was never the world’s most complicated watch. When it debuted, the Star Caliber 2000 ranked fourth in the official tally of complications, behind the Patek Philippe’s own Caliber 89 and the famous Henry Graves Super Complication from 1932, as well as the lesser-known Leroy 01 from 1904. Over the past quarter century, the Star Caliber 2000 has fallen down the rankings as more complicated watches, for both the pocket and the wrist, have been developed by Vacheron Constantin and Audemars Piguet. But the Star Caliber 2000 should not be judged solely by this kind of ranking, which is largely superficial. The watch is packed with a number o...

The ETA 2824 caliber has been a presence in the world of mechanical wristwatches for more than 50 years, helping the Swiss watchmaking industry forge a path through the Quartz Crisis and serving as the engine for hundreds of three-handed timepieces from an array of brands, large and small. While it is a rarity here in the 21st Century, its legacy can still be seen across the horological world - from the proliferation of similar movements by makers like Sellita to the increasing ubiquity of the ETA 2824’s souped-up successor, the Powermatic 80. Read on to learn everything you need to know about the ETA 2824. A (Very Brief) History of ETA Nearly everyone that follows the wristwatch industry has heard of ETA, and most of those have probably worn a watch with an ETA movement, but few are likely aware of the Swiss movement maker’s long and convoluted history. We generally trace its origins back to the formation of the historical watchmaking firm Eterna, in 1856 in the Swiss town of Grenchen. But in reality its roots reach even deeper. Eterna is perhaps most famous today as the maker of the Kon-Tiki dive watch, and it is currently owned by the Hong Kong-based Citychamp Watch and Jewellery Group. Originally however, the firm was a manufacturer of ébauches - unassembled movements for sale to outside watchmakers - and was named “Dr. Girard & Schild” for its founders, Dr. Joseph Girard and Urs Schild. Renamed Schild Frères by the next generation of owners, the compan...

It tends to be a big deal when a watchmaker unveils their first “in-house” movement, a pivotal milestone that often marks a step into the upmarket. For Italian brand Venezianico, tapping into the expertise of Fausto Berizzi, the technical director of OISA, was the key to their first proprietary mechanical caliber, designed, registered, and built entirely in Italy. The result is the Redentore Utopia, and its beating heart: the V5000 Caliber mechanical movement. In a break from convention, the Redentore Utopia is more of a stage for the V5000 Caliber movement-a catalyst for the Venezianico brand and its future momentum. Still, Venezianico matches the enthusiasm of the movement with a visually-gripping timepiece that certainly doesn’t signal its status as simply a vessel for the brand’s technical growth. Wearing a 316L stainless steel case that measures at 38mm in diameter and 8.9mm in thickness, the Utopia is firmly a dress watch. The deep blue dial is constructed via ion plating and features a dazzling, hand-engraved guilloché pattern, designed exclusively for the Utopia on a rose engine lathe by master artisan Riccarfo Renzetti. The result is a radial motif that gives the appearance of being in constant motion, with light glancing off each angle as the watch is shifted on the wrist. On the dial, baton-style, hand-applied indices line the circumference, and faceted alpha hands match the stainless steel case’s polished finish. The sole text detail on the dia...

Seiko introduced a new caliber back in March via their Prospex GMT Diver collection, adding caller GMT functionality into the brand’s well understood contemporary dive watch platform. Those watches have generated quite a bit of chatter in the watch community, with many singing their praises with respect to overall fit, finish, and wearability, and others wishing for a more functional flyer GMT complication. While the dust might still be settling, Seiko marches on, with the latest crop of watches to feature their still new 6R54 GMT movement. This time, Seiko brings the movement to the Alpinist family, which seems like a natural place for a GMT equipped watch to land. It takes what has always been cast as an explorer’s watch (with its signature compass bezel) and gives it a modern, practical, mechanical complication for a different kind of exploration. I’ve always been a pretty big fan of the Alpinist for many of the reasons Blake identifies in his Missed Review. There’s something charmingly anachronistic about wearing a watch designed with such an old fashioned aesthetic (those cathedral hands, especially) but built to modern sports watch standards. With a GMT complication added, the Alpinist retains a lot (maybe all) of that old fashioned charm, just slightly tweaked. The Explorer-style steel 24 hour bezel gives these watches a clean and sporty look, and we still get the trademark handset and those big numerals (just at the cardinal positions here, rather than ev...
