Hands-On With The Zenith Defy Skyline Chronograph Skeleton

What would happen if you started working out in 1969? How would you look today? Well, if you were a watch, you would probably look like the 42mm Zenith Defy Skyline Chronograph Skeleton. When the athletic Defy A3642 came to life 56 years ago, the watch, with its muscular octagonal case and chiseled tetradecagonal (14-sided) […] Visit Hands-On With The Zenith Defy Skyline Chronograph Skeleton to read the full article.

Breitling’s Flagship Navitimer B19 Perpetual Calendar Chronograph in Steel SJX Watches

Breitling’s Flagship Navitimer B19 Perpetual Calendar Chronograph in Steel

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...

Video Reaction: the Bulova Snorkel Collection

The other day, I got to sit down and take a look at the new Bulova Snorkel collection. They caught my attention for a simple reason: they are literally eye-catching. The brand’s first foray into the new world of “hybrid” ceramics, they bring an unexpected dose of color to a well-liked, if a bit cult, vintage model: the amusingly named “Devil Diver.” In the video below, I go hands-on with this new collection and give you my thoughts on this trend of not-quite-plastic watches and, of course, the Snorkels themselves.

The Evergreens – An Interesting Case… The History of the Almost Century-Old Jaeger-LeCoultre Reverso

Today, there is only one Reverso, with Jaeger-LeCoultre printed on its dial, but this was not always the case. During the 1930s, Patek Philippe, Vacheron Constantin and Cartier made watches that used the Reverso case for their timepieces. Moreover, the 1931 Reverso was not the first reversible case design. A few years earlier, Universal Geneve […]

Recapping the Launch Event of the Citizen Premier Collections

  On the evening of Thursday, February 27th, atop Freedom Tower at the World Trade Center in NYC-with a perfect view of Citizen’s US headquarters within the Empire State Building-Eric Horowitz, the brand’s Managing Director, announced the formation of a new division within Citizen. Dubbed Citizen Premier, this new endeavor represents what Citizen describes as “the pinnacle of watchmaking,” and highlights their ability to marry technological innovations with high-end Japanese craftsmanship in what will be a range of higher end, more refined products, all while maintaining the tried and true value-driven offerings we’ve come to appreciate more and more in recent years. Citizen Premier is an entirely new category within the Citizen ecosystem that launches with two of their most popular brands: Series8 and Attesa. These collections push the boundaries of Citizen’s movement technology and materials expertise. Series8 incorporates bold, contemporary designs into modern sports watches housing automatic movements, while Attesa places a focus on Super Titanium, Eco-Drive technology, and avant-garde design. It’s clear that Citizen views this announcement as a major milestone at a time when the brand is enjoying renewed strength in the enthusiast market. It’s no secret that Citizen has been on a run lately with watches targeted directly at the enthusiast community. Chances are you’ve spotted various Citizens on wrists at Windups and meetups more frequently now ...

Isotope Introduces a Pair of Mercury Limited Editions for British Watchmakers’ Day

Suppose you travel frequently between the US and Britain. In that case, one difference you’ll notice pretty swiftly after escaping the airport is the proliferation (and absence) of flags depending on which side of the pond you have arrived. Over here, you’ll typically only see a Union Flag flying outside official buildings, or on literally everything inside the many tourist shops around London. It’s not generally seen outside schools, homes or shops. However, we Brits do let a smidgen of patriotism creep out on occasion. The “Last Night of the Proms” even encourages flag waving (and rhythmic bobbing), and we feel a sense of pride celebrating Olympic medals won by superhuman efforts from individuals we only heard about two and a half hours earlier. Display the Union Flag on a watch and most Brits would turn their nose up. A stylized version of the same idea, but created by a watch brand based in the south of England, started by a gentleman from Portugal, and available in very limited numbers, and it’s a whole lot more acceptable. Sometimes we take a little outside encouragement to embrace such things. Isotope is unveiling two watches for British Watch Makers’ Day 2025, which both make vivid use of the Union Flag – the Mercury BWD Cloisonné and Mercury BWD Micro Marquetry. Isotope’s Mercury was first seen last summer in the form of a limited edition with Revolution, and was followed by a Shadow variant which used the same case and movement but a brushed in...

Only For Japan – The Biver Automatique with Grand Feu Enamel Dial

Jean-Claude Biver and his son Pierre continue their journey of independent horology with the Biver Automatique Japan Edition. Made in collaboration with its retailer in Japan, this special release is based on the time-only automatic debuted last year, but reimagined to cater to the traditionally classical taste of the Japanese collector. The minimalist edition debuts in two elegant variants that explore the contrast of light and shadow through hard-fired enamel made by an enamel workshop in Geneva’s Old Town. A stark white enamel dial is paired with a platinum case, while the high-contrast version matches a glossy black dial with a rose gold case – both share a clean, old-school aesthetic with applied markers and a railway minute track. A tribute to the Japanese collector The Automatique epitomises Biver’s neoclassical and elaborate approach to watchmaking, which blends careful detailing with hand-finishing techniques, for both habillage and the movement. Now the Japan Edition further refines the approach, condensing the more elaborate execution of the original versions into something more traditional, more classical, and arguably more reflective of the taste of Japanese enthusiasts. The two distinct models pay homage to the Japanese appreciation of minimalist aesthetics combined with high quality and precision execution, along with a well-established love of mid-century precision Swiss wristwatches. The clarity of the vintage-inspired design makes the Japan Edition ...

Konstantin Chaykin Returns with Slavic Bread-Creature Wristmon

Drawn from a Russian fairy tale about a bun coming to life, the Kolobok 2 arrives a year after Konstantin Chaykin revealed the original Kolobok. Like its predecessors in the Wristmon collection, this features a dial inspired by the titular character’s face. But the Kolobok 2 marks a departure from the first version in two notable ways: it is now a regular production watch rather than a limited edition, and it features a La Joux-Perret base movement instead of an ETA. Initial thoughts The Kolobok 2 is the latest of many Wristmon models, arguably too many to date. However, the fact that this is a regular production model, as opposed to a limited edition, is a positive development since it indicates the brand is leaving behind the multiple-edition approach. That aside, the watch itself is an upgrade over earlier versions. Although the new Kolobok 2 has the same simple functions arranged as a face, it is powered by a new movement based on the La Joux-Perret G200, replacing the modified ETA 2892-A2 used in preceding entry-level Wristmon models. This calibre is a step forward for the Wristmon model. Amongst other things that put it ahead of the ETA 2892, the G200 sports a a full balance bridge with a free-sprung balance. Another wristmon The Kolobok 2 retains the same dimensions and technical specifications as its predecessors, measuring 40 mm in diameter and 12.2 mm in thickness. As with all Wristmons, it features a notched bezel with 12 screws and a case that’s predominan...

Insight: Regulating a Mechanical Watch Movement SJX Watches

Insight: Regulating a Mechanical Watch Movement

A mechanical watch is not always spot on; less-than-perfect timekeeping can happen, often due to an unruly oscillator. The solution is direct adjustments to the hairspring and balance assembly, either slowing down or speeding up the oscillator, a practice known as regulation. Watchmakers have devised multiple innovations to achieve this, including the free-sprung balance, exemplified by the Gyromax of Patek Philippe and Microstella of Rolex. While a simple concept in principle, the mechanics and practice of regulation are nuanced. Here we’ll delve into the theory of regulation and the primary regulating systems: the curb-pin regulator and the free-sprung (or variable inertia) balance. The Lange L043.4 with a screwed balance inspired by pocket watches Basic concepts In order to better understand watch regulation, we need to first cover some of the basic physics behind the watch oscillator: The component responsible for the running rate of a movement is its regulating organ. The regulating organ is made up of a hairspring paired to a balance, which together are also known as a harmonic oscillator. The natural oscillation period is the time it takes the balance to make a full swing, back and forth. The period is made up of two vibrations, one for each direction of the balance motion, with the escapement being unlocked at each vibration. Notably, the natural period of a balance wheel is intrinsic to itself and does not depend on the escapement type or the going train ratio. ...

[VIDEO] Hands-On: the Zenith Defy Revival Diver

For most of my watch-buying life, fun dive watches have mostly been big dive watches. Colorful, loud, capable waterproof options have tended to correspond with case dimensions of equal impact and presence, while the sub-40mm dive watch space has belonged to relatively sedate interpretations of the classic dive watch formula - and even then, 39mm has been the sweet spot for ‘small’ divers. But over the last few release cycles (if those even exist anymore), we’ve started to see signs of a shift, and I can think of few better examples of this change than the Zenith Defy Revival Diver A3648, released last year as part of Zenith’s grand re-entry into the dive space. Last summer, I got to spend a few weeks with the Zenith Defy Revival Diver’s bigger, brasher brother, the Defy Extreme Diver, and I came away wildly impressed. The Defy Extreme Diver was a watch that punched way above its weight class (or at least its price point) while feeling like a genuinely novel take on a modern dive watch from a brand with shockingly little history in the space. So when I had the chance to spend some time with that watch’s vintage-inspired counterpart, I jumped. This extended visit with the Revival Diver wasn’t my first hands-on experience with the watch - I got to spend a few minutes with it when I went to pick up the Extreme Diver back in June - but on that day, I didn’t find myself particularly taken with the Revival. While I’ve long admired Zenith’s dual identity...

Anoma Debuts the A1 Slate Worn & Wound
Mar 6, 2025

Anoma Debuts the A1 Slate

In a monochrome, modernist twist on the recently released A1 First Series, London upstart brand Anoma-short for Anomaly- has announced its followup, the appropriately named A1 Slate. Sharing the same smooth triangular shape with rounded angles and an offset face, the A1 Slate was similarly inspired by a free-form table designed  by Charlotte Perriand in the 1950s, and Constantin  Brâncuși’s modernist sculptures. The new gray, black, and white color scheme, however, promises a more subtle take on the shape that aligns more with the third inspiration-river stones, smoothed over time by passing water.  The 316L stainless steel triangular case is likely the first detail on the A1, whether the First Series or the Slate, that an observer will notice. Measuring in at 30mm x 38mm (though Anoma notes that the shape and lack of lugs make the fit closer to 37mm), the case is mirror-polished, and meant to refract and bend light at every angle. Without having the watch on hand, I can’t vouch for this effect, but Worn & Wound’s own Zach Weiss reviewed the A1 First Series back in January 2024 and attested to the charm of the watch’s styling and finish. The vertically-brushed dial itself stands out against the case, with individually-engraved contrasting inner triangles coated with three layers of glossy black lacquer. Leaf hour and minute hands adorn the dial, with the Anoma logo below the centerpoint. A cleverly-situated cross with lines at the 12, 3, 6, and 9 o’clo...

Seiko Revives the Funky, Facetted King Seiko Vanac

In the 1970s, arguably no watch brand was having more fun than Seiko, which launched the bold King Seiko Vanac collection in 1972. Five decades on, Seiko returns to the concept with the all-new King Seiko Vanac, with bold dial colours and an angular, faceted case inspired by its namesake. Despite an entirely new design – the modern-day Vanac is not a remake – the collection captures the style and spirit of the funky 1970s originals perfectly. Available in five different dial colours, each inspired by the Tokyo skyline at a different time of day, the Vanac also features a new automatic cal. 8L45, now the highest-spec movement for Seiko’s mid tier watches. Initial thoughts The past decade has treated us to more than our fair share of vintage reissues, which by and large have focused on the glorious designs of the 1950s and 1960s. But there are only so many historical designs from this era that a brand can revisit, and as we move into 2025, it’s nice to see a little variety as Seiko looks to the 1970s. And while the Vanac is very much vintage inspired, it isn’t quite a reissue of any particular historical model. Though the bracelet is integrated, the design is different enough from Gerald Genta’s designs that it avoids the common pitfall of looking like it’s trying too hard to look like something else. A selection of vintage Vanac watches The Vanac features a 41 mm case that is quite chunky at 14.3 mm. The case itself is essentially an elongated hexagon, with a ...
