Happenings: Claude Greisler To Lecture At The Horological Society Of New York

Resonance is one of the most fascinating physical phenomena explored in watchmaking, where two oscillators influence each other and eventually synchronize. Since Christiaan Huygens' 17th‑century observations with pendulum clocks, watchmakers have sought to harness it in wristwatches. At the May 2026 lecture of the Horological Society of New York (HSNY), Armin Strom Co-Founder and Master Watchmaker Claude Greisler will share how the brand successfully achieved resonance in 2016 with the caliber ARF15. Central to this innovation is the patented resonance clutch, which links the two hairsprings, allowing them to synchronize quickly and continuously average out rate deviations. Join Greisler as he explores the journey from theory to mechanism and the creation of a modern resonance system. About Claude Greisler "A passion for 'transparent mechanics', both from an aesthetic perspective and to showcase how our watches actually work, has always guided my design sensibility. From a watchmaking perspective, I honor the many generations of Swiss-German watchmakers in my family with an uncompromising commitment to perfection in both movement quality and finishing." - Claude Greisler Born into a watchmaker family, Claude Greisler began his formal watchmaking education at a watchmaker school in Solothurn, Switzerland, followed by advanced programs at the Centre Interrégional de Formation des Montagnes (CIFOM) in Le Locle. He graduated in watch restoration and watch development, com...

Watches & Wonders: Oris’ 24-Year-Old Product Design Engineer Just Reworked a Classic - This is the Sleek New Artelier Complication Worn & Wound
Oris 24-Year-Old Product Design Apr 15, 2026

Watches & Wonders: Oris’ 24-Year-Old Product Design Engineer Just Reworked a Classic - This is the Sleek New Artelier Complication

Oris first introduced its Artelier Complication in 1991 alongside the Caliber 581, which notably featured a moonphase module developed in-house by the brand. The release marked another significant moment for the maison in its commitment to manufacture movements following the quartz crisis. The model’s presence ultimately faded but received new life in 2017 with an updated design that featured a more modern, cleaner style with slimmer, tapered lugs, and a redesigned bezel. At Watches & Wonders, we get the next evolution of the Artelier Complication.  The newest incarnation gives us another redesign from the 2017 edition while keeping the focus on highlighting the romantic moonphase. This updated take on the Artelier Complication comes from 24-year-old Lena Huwiler, Oris’s new Product Design Engineer. Huwiler has been able to achieve the perfect balance between honoring the model’s place in the history of the brand and propelling it forward with a design that will resonate with her generation. An old soul at heart, Huwiler admits she does not just find inspiration online but still appreciates architecture, crafts, and interior design. She clearly brings the duality of these sensibilities into her design for the new Artelier Complication. Here, Huwiler has given an Oris classic a modern, urban profile and reworked the moonphase display designed by and for the next generation of watch collectors. The major update here is in the complication and how it is presented thank...

Watches & Wonders: TAG Heuer Reinvents (a part of) the Chronograph with the Monaco Evergraph

When I think of Heuer, or TAG, or TAG Heuer, for that matter, I think of chronographs. You probably do too. Carreras, Monacos, Autavias, Monzas, Veronas, Montreals, etc… All iconic models, their pursuit of the stop-watch-in-a-wrist-watch goes far beyond just that of aesthetics. Famously, in 1969, they were among the first three brands to introduce an automatic chronograph with the Caliber 11. Then, in the 2010s, they pushed chronograph innovation to its limits with high-concept, high-frequency calibers like the Mikrograph, Mikrotimer, and Mikrogirder. In the last few years, TAG has focused more on the commercial side, honing in on a contemporary design language with the glass box Carreras, as well as a workhorse caliber of their own, the 80-hour, column-wheel, automatic TH20. 2026, however, marks a return to more innovative, if high-end times. Earlier this year, they introduced the six-figure Carrera Split-Seconds Chronograph, a 36,000bph rattrapante made in collaboration with Vaucher, under the category of “avant-garde horlogerie.” A curious development that was perhaps undermined by having such a daunting price, it did serve as an amuse-bouche to their big Watches & Wonders novelty: the Monaco Evergraph, which includes at least one first in watchmaking. There is a lot to unpack with the Evergraph, but the movement is a good place to start. Inside is a new caliber called the TH80-00. An integrated chronometer-certified automatic chronograph with 47-jewels, it featur...

Watches & Wonders: Grand Seiko Introduces the SBGY043 “Iwao Blue” Worn & Wound

Watches & Wonders: Grand Seiko Introduces the SBGY043 “Iwao Blue”

At Watches & Wonders 2026, Grand Seiko’s newest addition to the Elegance Collection brings together the things it does best. Namely, intricately textured dials with a nod to Japanese artistry, and its flagship Caliber 9R Spring Drive.  Engraved to resemble a weathered rock face, the SBGY043’s striking dial suggests the appearance of a mountain at dusk: Grand Seiko calls this pattern iwao, which translates to rock or crag. Depending on the angle it’s viewed from behind its domed sapphire crystal, different facets take on intermingling light and dark tones of blue, purple, and black. Its color is inspired by the tradition of katsuiro dyeing, a centuries-old technique and reportedly a favorite among the samurai class, which produces a deep indigo hue. Set against bright silver markers and hands - no blued seconds hand here, which is almost its own Grand Seiko tradition - it makes for an especially understated contrast.  This Iwao Blue version runs on the Caliber 9R31, a manual-wind Spring Drive movement with a 72-hour power reserve and visible through a clear caseback. The case is among the slimmest in the Elegance Collection, with standard zaratsu polishing and soft, rounded lugs. A nine-row stainless steel bracelet is the only option, which reflects the craggy-faced dial’s aura of ruggedness.  Grand Seiko enthusiasts, of which there are many, might remember this dial from 2021 - albeit in a sharp-angled Heritage case and with a Caliber 9R65 Spring Drive mov...

Watches & Wonders: Zenith Expands the Chronomaster Sport Line with New Skeleton References, Plus a Two-Tone Version with MOP Dial, and a New Micro-Adjustable Clasp

Zenith has released five new references under the Chronomaster Sport umbrella, most notably with four skeletonized versions of the design, as well as a dressier two-tone option. To understand the new skeletonized editions, it’s probably best to start at the beginning. When Zenith introduced the El Primero in 1969, it launched what is widely regarded as the world’s first automatic, integrated high-frequency chronograph caliber, a movement that has remained central to the brand’s identity ever since. The Chronomaster collection has long carried that legacy forward, and with this new series of skeletonized watches, Zenith brings that movement further to the forefront. All of the skeleton models run on the El Primero 3600SK, the openworked version of Zenith’s high-frequency automatic chronograph. Like the standard El Primero 3600, it beats at 5 Hz, which allows the central chronograph hand to complete one full rotation every 10 seconds and display 1/10th of a second directly off the bezel. The movement also offers a 60-hour power reserve, while the open dial and caseback give a clear view of the column wheel, horizontal clutch, and star-shaped rotor. All come in the now familiar 41mm Chronomaster Sport case. In regards to the design of the Chronomaster Sport Skeleton models, the biggest visual shift comes from the opened-up dial. The collection includes two stainless steel versions: one with a black ceramic bezel and the signature grey, anthracite, and blue tri-color c...

Felipe Pikullik Goes Fully In-House SJX Watches

Felipe Pikullik Goes Fully In-House

Berlin-based Felipe Pikullik presents his second in-house caliber inside the Sternenhimmel FPA1. The independent’s attempt at a refined workhorse-like movement comes in the form of the newly-developed caliber FPA1, designed to power a range of future creations.  Initial thoughts Mr Pikullik’s emergence into the crowded independent watchmaking scene was based on heavily skeletonised off-the-shelf movements. As he gained a reputation for deft finishing and began to consolidate his workshop, he slowly but surely transitioned toward in-house engineering. Starting with his own complication modules, the German watchmaker’s first truly in-house effort came with last year’s Moonphase II collection, which saw the launch of the calibre FPMP2.  The openworked construction featured a moon phase and 24-hour indicator but, while undoubtedly well-crafted, it arguably lacked a cohesive design language. Its distinctive architecture also made it unsuitable as the foundation for a wider range of pieces. In contrast, the updated Sternenhimmel (German for “starry sky”) features what the independent watchmaker describes as a cornerstone movement for future models. The FPA1 is consequently far more grounded and classical in construction, yet manages to avoid the trap of looking too much like any other artisanal time-only calibre. The ornate backside of the FPA1 caliber. This specific iteration of the Sternenhimmel design is decidedly more modern and technically-oriented, with a flo...

Best of Both Worlds for The Citizen’s 30th Anniversary

Citizen marks 30 years of its upmarket The Citizen collection with a matching pair of limited-edition 30th anniversary watches with aquiline ivory dials. Representing the best of both worlds, the pair offer Citizen’s best calibres in mechanical and analogue quartz watchmaking: one contains the automatic Caliber 0200, while the other boasts the top of the line, feature-rich Eco-Drive A060. The Citizen Caliber 0200 30th Anniversary Initial Thoughts While little known outside Japan and certain enthusiast circles, the eagle-crested The Citizen watches are arguably the best Citizen has to offer, and also a tantalising value proposition. Both models are good in their own right, though the automatic is the winner here. The Calibre 0200 model is probably the best made-in-Japan integrated bracelet sports watch currently available, combining the impressive case and dial finishing we’ve come to expect from premium Japanese watches, and a significantly more upscale movement than the King Seiko Vanac or Credor Locomotive. The quartz model is appealing, The Citizen has plenty of other quartz offerings with the same movement but more interesting dials. The Citizen Eco-Drive 30th Anniversary Eco-Drive cal. A060 The conical bezel and flat lug chamfers of the Eco-Drive model are flat polished using a spinning tin-plate, creating a near distortion-free mirror finish.

Grand Seiko Introduces the SLGB005 “Violet Dawn” Worn & Wound
Grand Seiko Introduces Oct 1, 2025

Grand Seiko Introduces the SLGB005 “Violet Dawn”

Earlier this year at Watches & Wonders, Grand Seiko revealed the SLBG003, which turned out to be one of the most impressive watches of the whole show. Housing the new 9RB2 Spring Drive caliber, the UFA (Ultra-Fine Accuracy) movement is certified to an almost incomprehensible +/- 20 seconds per year, or roughly 3 seconds per month. That makes it, according to Grand Seiko, the most accurate movement powered by a mainspring. It’s a truly impressive horological achievement.  Of course, as soon as a brand like Grand Seiko introduces an entirely new platform like the UFA, enthusiasts are on pins and needles waiting to see what comes next. It’s not that we can’t appreciate what we have in front of us, but particularly with Grand Seiko, we know that variants are coming in the form of new dial options and case materials. If you had asked me in the Spring when we’d see the first derivation on the UFA line, I probably wouldn’t have expected to see a new watch so soon, but last week Grand Seiko dropped the Evolution 9 Spring Drive UFA SLGB005, nicknamed the “Violet Dawn” for its deep purple dial. It’s always interesting to see what new watches in a new sub-collection come to pass, not just for what it says about where the line is going, but perhaps where it’s not.  The SLGB005, like its predecessor, is what we’d probably call a small-medium size by today’s standards, measuring a conservative 37mm. Unlike the titanium SLBG003, however, this watch is clad in a st...
