Breitling Introduces the Top Time B01 Racing Chronograph with a Little Help From an Automotive Icon
While more marketable leagues like Formula 1 entice with hypercars, social media presence, and reality TV, rally racing continues to wow spectators with its gritty and furious breed of off-road motorsport. Still, the rally world isn’t without flashes of luxury, and Breitling’s three new Top Time B01 Racing models look to celebrate the sport in all its dirty, dangerous beauty. Fortunately, the Swiss brand has a wealth of innovations to pull from their Top Time line-most notable is the “dashboard” dual-chronograph dial design that helps give the new Racing models that rally-inspired edge. All three Racing models are anchored by a stainless steel cushion case that gives the watch a squared-off and recognizably retro-futuristic look. With a 38mm diameter and a 44.4mm lug-to-lug measurement, the Top Time Racing should wear comfortably on most wrists but remain legible-both important factors to consider in motorsports, where one wasted second could spell disaster (or mortal danger). Raised, grooved sections add texture and dimension to each rounded corner of the case and mirror the tight spacing of the ¼ second dashes around the dial. All three models feature perforated calfskin straps nestled within an 18mm lug width, a design that calls to mind vintage racing gloves but still emphasizes durability and sportiness. The aforementioned “dashboard” dual-chronograph dial mimics an instrument cluster, with “squircle” (yes, Breitling does call them that) subdi...

[VIDEO] Grand Seiko Redefines Accuracy - Again: Introducing the 9RB2 U.F.A. Spring Drive Caliber
2022: the Kodo constant force tourbillon. 2023: the Tentagraph hi-beat mechanical chronograph. 2024: the 9SA4 manual wound, hi-beat, dual-impulse escapement caliber, and Kodo Daybreak. It’s easy to forget that Grand Seiko has brought the proverbial heat to Watches & Wonders every year since the fair started, unveiling something that one could call “revolutionary” for the brand, if on varying scales. Well, it’s looking like 2025 will continue the trend with the introduction of Spring Drive Caliber 9RB2, the first caliber with U.F.A., or Ultra Fine Accuracy, designation. Before proceeding, there are two important concepts to understand: Spring Drive and Grand Seiko’s history with acronyms (which, if you know, feel free to jump two paragraphs ahead). Starting with the former, the elevator pitch, which I will take from our article dedicated to the topic is “Spring Drive combines the best of mechanical watchmaking and the best of quartz timekeeping to create a state-of-the-art caliber that lacks the weaknesses inherent to both of these movements.” A bit deeper, Spring Drive movements use the energy stored in a traditional mainspring to drive their proprietary “Tri-synchro” regulator, which replaces the classic lever escapement. It consists of a glide wheel, the rate of which is controlled by an electromagnetic brake, and is essentially regulated by an integrated circuit with a quartz oscillator. The result is a mechanical movement with quartz-like accuracy and...

Up Close: Citizen Caliber 0210 “The Citizen”
Citizen launched its flagship mechanical watch, the Caliber 0200, two years ago. Despite being better known for high-end quartz watches – including the most accurate ever – the Japanese watchmaker managed an impressively executed three-handed sports watch, with an equally outstanding new movement. Now the model finally receives a mechanical upgrade with the Caliber 0210, which incorporates a date along with subtle improvements to the external design, while retaining the excellent case and bracelet that define the model. Initial thoughts The Caliber 0210 indicates the brand’s interest in further developing this excellent model – encouraging for fans of the model like myself. Despite the Caliber 0210 looking much like its predecessor, it is actually a substantially different watch in tangible terms. Ordinarily the addition of a date would be a no-no for a purist enthusiast, but here the date is integrated well in terms of dial proportions and (re)design. The appealing attributes of the Caliber 0200, and now the Caliber 0210, clearly mark the two out as watches conceived for a niche audience, namely enthusiasts who appreciate quality – and are able to distinguish this from the competition (Grand Seiko to state the obvious). However, this target audience often prefers the purity of a three-hand watch without a date. At the same time, this audience comprehends the substantive upgrades in the Caliber 0210 beyond the date – amongst them the improved case constructi...

Breitling Introduces the Navitimer B01 “S&S; 10th Anniversary”
Breitling is introducing a luxe variation of its flagship chronograph to mark the tenth year of S&S; Group, a luxury retailer that represents brands ranging from Rolls Royce to Richard Mille in Vietnam. The Navitimer B01 “S&S; 10th Anniversary” Limited Edition is making its debut just in time for the opening of the Breitling boutique in the Vietnamese capital, Hanoi. Initial thoughts Highlighting its focus on Southeast Asia, it comes as no surprise that Breitling has unveiled another edition of its trademark chronograph, following the Singapore Airlines edition from last year. But instead of a mere change of colour as it usually does, Breitling has employed mother-of-pearl for the dial, an unusual material for the brand but one that adds a touch of extravagance to an otherwise functional pilot’s watch. The mother-of-pearl dial instantly sets this apart from the standard Navitimer, particularly with the red gold case. Perhaps the only thing missing is the retailer’s logo on the dial, a detail that would hark back to the double-signed dials that are desirable in vintage watches. Priced at US$21,800, the S&S; Navitimer is slightly more expensive than the standard production model in rose gold that has a plain, cream dial. This increase can primarily be attributed to the mother-of-pearl dial and seems fairly proportional for the upgrade in dial material. Tenth anniversary This Navitimer edition celebrates the tenth year of S&S; Group, which was founded in 2013 as the s...

This 1932 Bulova White Prince jump hour / direct read dress watch is truly rare, and this example is in superb condition.

Grand Seiko Introduces the Caliber 9S 25th Anniversary SBGH311 and SBGR325
When Grand Seiko (GS) made its return in 1998, the inaugural SBGR001 model was powered by the 9S55, the first modern-day GS calibre. Now the brand is marking the 25th anniversary of the 9S movement family with a pair of limited editions. The Heritage Collection Caliber 9S 25th Anniversary Hi-Beat 36000 SBGH311 and the Heritage Collection Caliber 9S 25th Anniversary SBGR325. The Hi-Beat SBGH311 has a patterned dial, while the more affordable SBGR325 has a dial with a brushed finish. Both are modelled on the original model of 1998 and sport the same 37 mm case. SBGH311 (left) and SBGR325 Initial thoughts With their 37 mm cases and clean styling, the new 9S pair hark back to the GS watches made from the late 1990s to mid 2000s. That is unsurprising since they are meant to commemorate the first model with the 9S movement, which made its debut in 1998. The Hi-Beat SBGH311 does have a fancier pattern dial, but one that is relatively subtle in its shades-of-grey texture. As a result, they will appeal to anyone who wants a smaller, simpler GS watch. Another upside of the relatively simpler execution are the prices, which place the pair amongst the most affordable self-winding GS watches. The SBGH311 is US$6,600 and the SBGR325 about 20% less. SBGR325 Old-school size The SBGH311 has a textured dial in silvery grey inspired by clouds that’s matched with a blued-steel seconds hand. And the “GS” emblem is gilded in a nod to the fact that this is an anniversary edition. Not...

Breitling Introduces the New Navitimer B01 in 41, 43, and 46 mm
Distinctive for its slide-rule bezel, the Navitimer is synonymous with Breitling. Having been in near continuous production since its introduction 70 years ago, the Navitimer has been offered in a bewildering array of iterations, but the 2022 Navitimer B01 returns to the roots of the model with a vintage-inspired design, but livened up with bright, metallic dials. Initial thoughts If you already like the Navitimer, the 2022 version is an appealing proposition. It’s essentially the traditional Navitimer design with Breitling’s in-house chronograph movement that has an excellent construction. The model is consistently priced given the in-house movement, while the design has enough vintage elements to give it a classic Navitimer feel. The dial colours, however, are modern, so this avoids being a vintage remake (which Breitling has done enough of). Of the three sizes, the 41 mm is identical to the vintage original, so it’s probably the perfect size. The 43 mm is probably still acceptable on most wrists, but the 46 mm will be enormous. If there is to something to criticise it is probably the wide range of models – two case metals, three case sizes, and a dozen or so dial types, though not every dial is available in every size. The number of choices feel too ambitious and confusing for a launch of a new model. Throwback design The new Navitimer is the first redesign of the model since current chief executive Georges Kern took the helm of Breitling in 2017. Unsurprisingly...

Citizen Introduces the Caliber 0200 “Japanese Armor”
A year ago, Citizen debuted its first all new, high-end mechanical watch in decades, The Citizen Caliber 0200. A wristwatch par excellence, the Caliber 0200 was so good that it was one of our tops watches of 2021. Now Citizen is following up with the Caliber 0200 “Japanese Armour”, the first limited edition of the model that’s available globally. Topped with a black ceramic bezel and textured dial, the samurai-inspired Caliber 0200 has a low-key aesthetic that still distinguishes it from the all-steel models. Initial thoughts Even though production hasn’t yet caught up with demand – there’s still a waiting list for the watch – the Caliber 0200 is still a niche product, just because it is a high-end, mechanical offering from a brand better known for its solar-powered or quartz watches, and mostly affordable ones at that. So a limited edition makes sense, since the small run will boost desirability and create buzz worldwide (Citizen did launch a 50-piece limited edition last year that was sold only in Japan). That said, the new edition is still very much a restrained design that’s almost monochromatic. It’ll be one of those watches that are recognised only by those in the know. Interestingly, both the new limited edition and the standard model stick to the same palette – grey, silver, and black – with the difference between the two being the quantity and intensity of each colour. On the limited edition, black becomes the dominant colour thanks to the ...

Hands-On: the Wolbrook JetFlyer and the New Jeambrun PS6402 Automatic Chronograph Caliber
I’d like to think I am a bit of a movement nerd. Not in the sense of knowing all of the technical attributes (actually, I wish I knew more there), but rather about what movements are on the market from the major suppliers. Hand me a watch, even with a complication, and I can probably tell you what movement it has in a matter of seconds (assuming it’s mechanical) by the positioning of the hands, complications, rotor bearing, etc. So, last fall, when I was handed a prototype of a new chronograph by Wolbrook and, upon seeing the dial, realized I had no idea what movement it had, my interest was piqued. The watch was the Wolbrook Jetflyer, which I have since had the opportunity to spend more time with. An extension of the French brand’s proven line of tool dive watches based on vintage models, the Jetflyer is their first foray into mechanical chronographs. As the name suggests, the Jetflyer is not meant as a “dive” chronograph, but rather as a pilot’s, though that’s largely semantics, as there are a lot of overlaps in design language (and the WR is 100m). I’ll get back to the particulars of the design, because what really stands out is the movement. $845 Hands-On: the Wolbrook JetFlyer and the New Jeambrun PS6402 Automatic Chronograph Caliber Case Stainless Steel Movement Jeambrun PS 6402 Dial Mattte Black Lume X1 Super-Luminova Lens Domed Sapphire Strap Leather or Bracelet Water Resistance 100m Dimensions 38 x 46mm Thickness 14.3mm Lug Width 20mm Crown Screw-d...

Zenith Reimagines Its Caliber 135 For The 21st Century
The year 2025 marks 160 years since the founding of Zenith in Le Locle, Switzerland, back in 1865. As watchmaking brands are wont to do, Zenith is commemorating this milestone by putting forward a watch for the occasion that’s representative of its storied history, as well as its own contemporary identity. Now, as Watches & Wonders 2025 kicks off, we are clear on how the brand aims to celebrate the occasion, and its chosen vehicle is a new collection inspired by Zenith’s own founder, complete with an update on its storied Caliber 135, which breathes fresh life into an old favorite movement. These are the conditions in which the rising star of the G.F.J. collection joins Zenith’s constellation. At the tail end of the 19th century, the mounting competition within the watch industry brought about a new standard of gauging the accuracy of movements, and watchmakers began employing observatory trials to signal to customers that their products were as accurate as possible. This was also at a time in which highly accurate timepieces were necessary for successful marine navigation. Before the COSC certification standards that are so rigidly defined today were coded, individual movements would be sent to observatories, where they would undergo testing procedures, as well as competitions for chronometry prices. Zenith details that it had been routinely entering chronometry trials as early as 1897. And, because a bit of healthy bragging is appropriate with brag-worthy achieveme...

Yema Introduces a New Skin Diver with their Micro Rotor Caliber
French watchmaker Henry-Louis Belmont established Yema in 1948 and quickly became known for manufacturing ultra-capable tool watches. By 1954 their production reached 130,000 watches and by the mid 1960s they were selling over 400,000 watches annually in 55 countries. Their motto “Time of Heroes” became their official slogan, and their watches were particularly suitable for diving, car racing, and military expeditions. Today, Yema is experiencing a resurgence and is introducing a new modern interpretation of their iconic Skin Diver. The Skin Diver Slim CMM.20 is not just another pretty face. Beneath the beautiful dark grey dial beats their in-house Calibre Manufacture Morteau 20 movement (CMM.20). It is rated for accuracy at -3/+7 seconds a day, has a power reserve of 70 hours, and is extra slim due to its micro-rotor. The watch measures 39mm in diameter, 47mm from lug-to-lug, and only 10mm tall to the top of the double-domed sapphire crystal. Despite being relatively thin, it is water-resistant to an impressive depth of 300 meters. Adding to its vintage styling is a dark grey, faded bezel insert covered by sapphire glass. Its lume pip, along with all the lume on the dial and markers, has that aged radium look, which complements the design very well. The watch comes mounted on a new slimmer Yema Scales bracelet, which integrates better with the Skin Diver’s slimmer profile. The screw-down case back offers a transparent view of the movement, featuring a black ALD (ato...

Depancel Introduces their First Série-R Watch with an Automatic Chronograph Caliber
Depancel has carved out a nice little niche for themselves making highly specific automotive and racing inspired watches. These watches are frequently geared directly at watch collectors who are already steeped in car culture, with colorways inspired by classic racing liverys and case designs that emulate specific vehicle designs. Their square shaped watch, the Série-R, might appear somewhat derivative of another famous square watch connected to the racing world, but it has its own thing happening that sets it apart just enough. And this one, surprisingly, is the first chronograph in the Série-R collection. Previous iterations of the Série-R have primarily been the home of a calendar complication with an execution that is chronograph-like, featuring subdials at 3, 6, and 9 for the calendar indicators. The new Série-R, in a “Tangerine” colorway and limited to 300 pieces, could have been easily predicted by Depancel fans. We get effectively the same layout as the calendar, but we’ve entered race mode with a three register chrono. The new Tangerine colorway looks great, with a blue base dial with a sunray finish in the interior circular section and vertical ridges outside to fill the square. Orange and white accents figure prominently throughout, with a bold stripe down the dial’s left side, crossing the 9:00 subdial. The case might appear like a standard square at a glance, but there’s a little more going on. The shape is meant to evoke a radiator grille,...
