Radial “Mount Iwate” Patterned Dial for the Grand Seiko Evolution 9

Grand Seiko’s latest release, the Evolution 9 Hi-Beat 36000 SLGH027 Limited Edition, is all about the textured dial as is typical of the brand. Inspired by the ridges of Mount Iwate, a volcano that’s near Grand Seiko’s Shizukuishi workshop, the radial dial motif is more deeply textured than earlier iterations of the “Mount Iwate” pattern. The rest of the watch is typical of the Evolution 9 “SLGH” model – a high-frequency automatic movement inside a Zaratsu-finish case in from Ever-Brilliant steel, a proprietary alloy with superior corrosion resistance and a brighter finish than conventional steel. Initial thoughts Of the many Grand Seiko dials, the new Mount Iwate motif stands out. While the latest dial shares the same radial style as the earlier “Mount Iwate” pattern, found on the Tentagraph SLGC001 amongst others, the dial of the SLGH027 has a deeper texture and more pronounced grooves, giving it an elevated aesthetic that is more striking. With so many variants, Grand Seiko’s textured dials are a little cliche at this point, but there is no denying that the watches are still impressively crafted and offer strong value, rivalling the strongest Swiss competition (except in terms of the bracelet). At US$10,500, the SLGH027 is priced similarly to equivalent prior models. While it is substantially more expensive than the average time-and-date Grand Seiko, the price is justified by the top-of-the-line cal. 9SA5, as well as the excellent case and dial wor...

Hands On: Patek Philippe’s Celestial Goes to Space

Perhaps the most surprising launch from Patek Philippe at Watches & Wonders 2026 was the Celestial Sunrise and Sunset Ref. 6105G-001. The ref. 6105G arrives over a decade after its predecessor, the ref. 6102 (2012), which in turn replaced the ref. 5102 (2002). While the prior model was an incremental evolution over the original, the ref. 6105G is a drastic redesign with its spaceship-inspired aesthetic and 47 mm (!) white gold case that wears unexpectedly well. The ref. 6105G is also an upgrade in mechanical terms with the addition of an elegant and simple sunrise and sunrise display that’s smartly implemented on the date ring, and driven by a clever compliant mechanism. And the ref. 6105G has another trick up its sleeve, a mechanism that accounts for summer and winter time (also known as daylight saving time), which shifts the time display as well as the date ring backwards or forwards as the seasons change. Initial thoughts Put simply, the ref. 6105G is weird but cool. Some of Patek Philippe’s recent experiments with design have been so-so in attractiveness, but the ref. 6105G scores well, maybe even the best amongst the brand’s adventurous designs. It’s unlike any other Patek Philippe ever with its huge case and integrated rubber strap, but it is appealing. Even though the star chart complication is a historical one descended from the Henry Graves Jr. “Supercomplication”, it feels like a perfect match for the sci-fi case. The case is huge at 47 mm, but the ...

First Look – The Breguet Experimentale 1, With 10Hz High-Frequency Tourbillon and Constant Force Magnetic Escapement

Innovation spirit and inventiveness have always been part of Breguet, specifically as its founder, Abraham-Louis Breguet, was responsible from 1775 onwards for so many of the watchmaking innovations of that era: the tourbillon, the perpétuelle watch, the natural escapement, the constant­-force escapement, the shock absorber, the Breguet balance-spring with its terminal curve, the gong-spring… In […]

Omega’s Speedmaster Dark Side of the Moon Returns

A hit when it was launched a dozen years ago – time does fly – the Speedmaster Dark Side of the Moon was the first-ever Speedmaster in ceramic. Now Omega has refined and reworked the concept – the case is now almost 1 mm thinner – while retaining the all-ceramic construction and distinctive aesthetic. The new Speedmaster Dark Side of the Moon (DSOTM) makes its debut in four variants. The first two stick closely to the original, right down to the same automatic cal. 9900 movement, but in a slimmer format. More notable is the manual-wind version containing the cal. 9908, the first DSOTM offering with this movement, making it even thinner. And it has no date to boot. Rounding out the quartet is the Speedmaster Grey Side of the Moon (GSOTM) that is also manual-wind but powered by the historically-based, Moonwatch-famous cal. 3861. This adopts the lunar-textured surface, front and back, first seen on the Apollo 8 edition. The first manual-wind DSOTM that has a black-and-red livery Initial thoughts Contemporary collectors are spoiled for choice when it comes to the Speedmaster, which is available in seemingly endless configurations. While that’s arguably a criticism, it demonstrates Omega’s industrial prowess, which enables the brand to deliver large volumes of watches that are objectively high quality and equipped with some of the industry’s best chronograph movements, without keeping customers waiting. Regardless of the shade of grey or black, the watches are ins...

Vacheron Constantin’s First Chiming Sports Watch, the Overseas Grand Complication

Vacheron Constantin (VC) continues its 270th anniversary festivities with its first minute-repeating sports watch, the Overseas Grand Complication Openface. In addition to the repeater, the manually wound movement also features a perpetual calendar, tourbillon, and rear-facing power reserve indicator. All of this is housed in a titanium case rated to 30 m, which is a notable degree of water resistance for a chiming watch. This is also the first Overseas model with the “Openface” treatment, which pays homage to rock crystal dials found in vintage clocks and pocket watches with a clear sapphire dial exposing the perpetual calendar works. Image – Vacheron Constantin Initial Thoughts It’s unusual, but a chiming sports watch makes sense considering the direction of consumer preferences for complications. That said, the minute repeater has been slow to make its way into sports watches, despite enjoying renewed popularity for the past few decades, due to the challenges of waterproofing the charging slide and preserving sound quality. This has created a perception of water resistance and sound being mutually exclusive, which has only recently been challenged. Audemars Piguet was an early pioneer with water-resistant repeaters, and now Vacheron Constantin has entered the fray with a water-resistant minute-repeating integrated-bracelet sports watch of its own. While 30 m of water resistance is low compared to other models in the Overseas collection, it’s significant for a ...

Affordable Seiko Sports Duo Exclusively for SE Asia

Seiko has just announced a pair of regional exclusives for its longtime distributor in Southeast Asia, the Seiko 5 Sports SSK043K1 and Prospex Speedtimer SSC951P1 Thong Sia Group Editions. Available only in Singapore, Hong Kong, Macau, Malaysia, and Brunei, the Thong Sia Group (TSG) limited editions are inspired by basketball, hence the salmon dials with black accents that echo the colour of the balls. The solar-powered Speedtimer chronograph Initial thoughts Seiko produces some of the best offerings in the affordable price segment, and the TSG duo demonstrate that amply with strong price-performance ratios. The Seiko 5 Sports, for instance, is an automatic with second time zone for 654 Singapore dollars, or about US$500. While the basketball link is a bit of a stretch, the metallic-finish copper (or “salmon”) dials are appealing. Though the shade is popular, the colour is less common in affordable sports watches in this price range, making this pair a little more interesting. The Seiko 5 Sports with a GMT function A handy travel watch The TSG edition is based on the Seiko 5 Sports GMT, which is basically a diver-style watch with a second time zone function. It has a stainless steel case that is 42.5 mm in diameter and 13.6 mm high. Water resistant to 100 m, the case is satin-brushed on top with mirror-polished bevels on the side of the lugs. In traditional Seiko 5 style, it has the crown positioned at four o’clock, which was originally conceived to indicate the w...

Citizen’s Affordable Series 8 GMT in Mother-of-Pearl

Having already debuted a thoughtful reissue of a pocket watch for its centenary, Citizen is continuing with the commemorative editions with something more affordable: the Series 8 880 100th Anniversary. Featuring a second time zone function and integrated bracelet, the watch has a tone-tone finish of brushed steel and blue-coated steel, matched with a blue mother-of-pearl dial. Initial thoughts The Series 8 GMT is most notable for being a “true” GMT – with an independently adjustable hour hand – at an affordable price point. It retails for just under US$2,000, and most GMT watches in this price segment have an add-on GMT function of an adjustable 24-hour hand instead. While the standard versions of the Series 8 GMT are in familiar GMT colours, including a blue and red “Pepsi” version, this anniversary edition is unusual with the blue case treatment and sky-blue mother-of-pearl dial. For someone who wants an affordable, functional dual time zone that looks different, this is a competitive proposition. A true-blue GMT The Series 8 GMT has a two-part case construction that allows for the unusual two-tone finish of grey and blue. A central section that’s coated blue slots into the case middle, giving it the twin blue flanks on either side of the bezel. Measuring 41 mm in diameter and 13.5 mm high, the case is entirely steel, with the blue components coated to achieve the blue finish. Like the other Series 8 models, this has alternating brushed and polished fin...

Out of Office: Exploring the Canadian Rockies with Citizen’s Team Promaster

Citizen is a Japanese watch company well known for its technical precision, quality, innovation and eye for design. Founded on principles that elevate society above self, Citizen has been producing timepieces for “all citizens of the world to enjoy” for over 100 years. While following this mantra means producing pieces for the average person, it also means producing time pieces for those who live a life full of adventure, those that seek to go deeper, go higher, and go farther than others have before. For these people, the Promaster line of watches was created.   In early July, I received an invitation from Citizen to “join us on an extreme adventure in the Canadian Rockies as we celebrate Citizen Protester’s 35th Anniversary with Team Promaster.” I instantly accepted despite not knowing what was in store. As I began preparing for this trip, I wanted to dive deeper into the history of Citizen as a brand, and their collection of Promaster watches, to expand my knowledge and hopefully gain some idea of what I’d be getting myself into. Now, Citizen states that “Promaster isn’t just a collection-it’s a mindset and a pursuit of endurance-a symbol of excellence, passion, and performance,” and after the adventure we went on, I can say it’s the truth. Each day saw us pushing ourselves to go higher, go deeper, and go farther than we did the day before.  In order to truly experience the Promaster line of watches, Citizen graciously allowed each of us to ...

Louis Erard’s Latest is a Regulator with a Traditional Grand Feu Enamel Dial

Swiss watchmaker Louis Erard has recently collaborated with Donzé Cadrans, a veteran in the enamel dials field since 1972. As a first for Erard, the Le Régulateur Grand Feu Enamel model is adorned for the first time with a traditional grand feu enamel dial. This partnership shows an expansion for the Swiss brand into new territory – and done with impeccable taste.  The use of grand feu enamel here marries technical precision and artisan craftsmanship. Each dial has to be made by hand, involving a meticulous process where layers of enamel are applied and fired at temperatures exceeding 800°C. This technique not only ensures vibrant and long-lasting colors but also demands an exceptional level of skill and patience, as even the slightest imperfection can require the entire piece to be redone. The result is a unique and exquisite timepiece, where no two dials are exactly alike, showcasing the harmony between tradition and innovation in watchmaking. The Le Régulateur model has an ivory-colored grand feu dial against the polished stainless steel case, giving a classic look for just about any occasion. The dial also features an hour and seconds counter subdials stacked at both the 12 and 6 o’clock mark. The colors are offset with a vibrant blue that both contrasts and marries the look together. With an automatic movement running on a Sellita SW266-1 calibre, you’ll have no trouble keeping time with this watch. The Régulateur is pulled together with a grey grained cal...

In-Depth: Girard-Perregaux’s True Constant-Force Escapement

Ten years after it arrived on market, Girard-Perregaux revived its most notable modern-day invention with the Neo Constant Escapement. Operating on the same principles as the original, the Neo Constant Escapement (NCE) features an upgraded movement inside a more compact case. A combination of a historical concept originating with Abraham-Louis Breguet and cutting edge horology, the NCE retains the defining invention of the original – a true constant-force escapement. “True” because the constant-force mechanism, comprising a lozenge-shaped silicon spring, is integrated with the pallet lever, which in turn interacts with a “natural” escapement of twin escape wheels. While the key concept has been retained, the rest of the NCE, however, has been improved over the original, with wearability in particular having been enhanced. Initial thoughts The fundamental concept of the NCE is appealing because it successfully combines a significant historical invention, Breguet’s double-wheel escapement, with an innovation that is entirely 21st century, a compliant mechanism in silicon. Both are brought together in an elegant yet ingenious manner. The basis of the movement is Breguet’s échappement naturel, the “natural” escapement with two wheels that has been adopted in the modern day, in a variety of modified forms, by Voutilainen, F.P. Journe, and Charles Frodsham. But the natural escapement here has been enhanced with a constant force mechanism made up of a single pi...

Review: Christopher Ward’s The Twelve 36MM (and 40MM)

Last month, I had the opportunity to put together a list of the three watches I would choose for a collection if I had a budget of $5,000. Though I stand by my choices, selected through detailed research and great care, I have one small confession to make: none of those watches had ever graced my wrist. Fearing the imaginary cries of “j’accuse!” lest my secret be discovered, I tried on one of the three at a local authorized dealer within the week. This second opportunity was graciously made possible by the editors at Worn & Wound. I’m two for three now, so thus begins a personal journey predetermined by the Horological Fates. For this review, I lived a full day in the life with The Twelve. Two of these were the highly anticipated 36mm reference – one on the classic integrated bracelet, and the other on the rubber strap option. I also sampled the 40mm stainless steel reference on the bracelet in order to properly compare them. My wrist circumference, for reference, is about 5.75 inches. Christopher Ward’s goal in this 36mm launch was greater inclusivity towards women and other smaller-wristed folks, and I’m uniquely situated to consider both sizing options from this perspective. Each watch spent a day (or more) on wrist, so I was able to assess my true feelings towards them after the immediate New Watch Glee wore off. As a newbie reviewer, one helpful piece of advice I received was to pay attention to first impressions, and run with that if it felt right. Whil...
