In a world where luxury watches often compete through complex complications and increasingly elaborate dials, the ELKA x Ace “Essence” MD09 takes the opposite approach. It strips away everything that isn’t essential, proving that true elegance often lies in restraint. Inspired by ELKA Watch Co.’s philosophy of “Form Follows Feeling,” the MD09 is a watch designed to be experienced rather than simply read.
A Collaboration Rooted in Minimalism
Created in collaboration with Ace Jewelers, the Serie D “The 36” Essence is a celebration of pure design. Limited to just 50 pieces worldwide, the watch removes traditional hour markers and numerals, allowing the dial itself to become the focal point. Instead of measuring time with visual precision, the MD09 invites the wearer to appreciate time through emotion and simplicity.
The Beauty of an Uninterrupted Blue Dial
The first thing that captures your attention is the stunning sunray blue dial.
Free from indices and numerals, the uninterrupted surface allows light to move effortlessly across the dial, creating changing shades of deep navy and electric blue depending on the viewing angle. The absence of visual clutter gives the watch a calming, almost meditative presence that is increasingly rare in modern watchmaking.
Designed to Feel Natural
Housed in ELKA’s signature 36mm pebble-shaped case, the MD09 reflects the brand’s focus on comfort and organic design. Its smooth contours recall vintage pocket watches, while the compact proportions make it equally suited to both contemporary and classic wrists.
Completing the design is ELKA’s distinctive Chevé-box sapphire crystal, whose generous curvature evokes the charm of vintage acrylic crystals while delivering the scratch resistance expected from modern sapphire.
Less Design. More Emotion.
The MD09 isn’t about displaying technical complexity. It’s about creating an emotional connection with the wearer.
By removing every unnecessary element, ELKA allows the dial, proportions and light to become the watch’s defining features. It’s a reminder that sometimes the most memorable designs are those confident enough to leave space for simplicity.
EyesOnTime’s Take
The ELKA x Ace “Essence” MD09 Blue Minimalist is a refreshing reminder that minimalism doesn’t have to feel empty. Every design choice has a purpose, from the uninterrupted blue dial to the perfectly balanced 36mm case.
For collectors who appreciate independent watchmaking, understated elegance and thoughtful design, the MD09 offers something increasingly rare in today’s market: a watch that whispers instead of shouting.
With the Delphis Art Deco, Chronoswiss presents a bold reinterpretation of one of its most iconic complications. Inspired by the design language of the Roaring Twenties, this new edition pays tribute to an era defined by artistic freedom, architectural clarity, and a fascination with modern progress.
The Art Deco movement that flourished during the 1920s reshaped the visual culture of its time. From architecture and graphic design to fashion and industrial objects, it introduced a new aesthetic built on geometry, symmetry, and refined contrasts. It was a period where craftsmanship met innovation, and where decorative arts embraced modernity without abandoning tradition.
These values resonate deeply with the philosophy of Chronoswiss today.
With the Delphis Art Deco, the brand translates this spirit into a contemporary mechanical sculpture for the wrist.
A Dial inspired by Art Deco Geometry
At the center of the Delphis Art Deco lies a dial that reflects the architectural elegance of the Art Deco era.
The main dial surface is nickel-coated and laser-structured, creating a subtle three- dimensional texture that plays with light and shadow. Its refined grey tone evokes the metallic elegance and restrained color palettes characteristic of Art Deco design.
Hovering above this surface is the distinctive Delphis display. At 12 o’clock, the jumping hour advances instantly at the top of each hour. At the center, the retrograde minute hand sweeps across the curved scale before snapping back to its starting position. At the lower part of the dial, the small seconds rotate continuously.
For the small seconds, Chronoswiss introduces a baby-blue azur tone, achieved through a unique lacquer on a hand-guilloché base. The intricate guilloché pattern is engraved in- house at the Atelier Lucerne using century-old machines, creating a dynamic texture beneath the Art Deco-inspired white typography.
The gold-plated minute ring adds a warm contrast to the cool grey dial and reinforces the geometric clarity that defines the entire composition.
Modern Presence – Crafted in Lucerne
The 42 mm case of the Delphis Art Deco is crafted from Grade 5 titanium and finished in a matte grey tone. Lightweight yet exceptionally durable, the material lends the watch a modern architectural presence while ensuring comfort on the wrist.
Paired with a black nubuck strap, the piece balances the bold mechanical architecture of the Delphis complication with a refined contemporary aesthetic.
Powering the Delphis Art Deco is the Chronoswiss Manufacture Caliber C.6004, developed together with La Joux-Perret. The automatic movement offers a 55-hour power reserve and is visible through the sapphire crystal caseback.
Inside, traditional finishing techniques meet modern engineering, reflecting the same philosophy that defines the watch itself: heritage craftsmanship expressed through contemporary watchmaking.
A new chapter for an Icon
The Delphis has long been one of the most recognizable complications within the Chronoswiss universe and has remained an icon since its introduction in 1996.
With the Delphis Art Deco, Chronoswiss revisits this emblematic complication through the lens of one of history’s most influential design movements.
A mechanical tribute to the Roaring Twenties – reimagined for the collectors of today.

The new Patek Philippe Celestial 6105G-001 is one of the most technically fascinating releases from Watches & Wonders 2026 — a Grand Complication that combines astronomical watchmaking with mechanically calculated sunrise and sunset indications.
While most high-complication watches focus on perpetual calendars, tourbillons, or chiming mechanisms, the Celestial collection explores something far rarer: the relationship between time and the cosmos itself.
With its rotating sky chart, sidereal time display, moon phase indication, and newly integrated sunrise and sunset functions, the Patek Philippe Celestial 6105G-001 pushes the manufacture deeper into astronomical horology while introducing one of the boldest modern case designs the brand has produced in recent years.
A Different Kind Of Grand Complication
The Patek Philippe Celestial 6105G-001 is not a watch designed around traditional complication hierarchy.
Instead of emphasizing elapsed time, acoustic complications, or calendar programming, the watch visualizes astronomical motion through a continuously rotating celestial display that recreates the visible night sky above Geneva.
At the center of the dial sits a sapphire sky chart displaying the movement of stars and the Milky Way as they appear from Earth. The display rotates according to sidereal time — a system based on Earth’s rotation relative to distant stars rather than solar time.
This is what gives the Celestial collection its unique identity.
It does not simply tell time.
It visualizes the passage of the heavens.
Despite the enormous amount of information displayed, the dial remains surprisingly legible. Patek Philippe avoids clutter by layering indications carefully across rotating discs, peripheral scales, and integrated apertures rather than overwhelming the wearer with traditional sub-dials.
The result feels immersive rather than chaotic.
The New Sunrise And Sunset Complication
What makes the Patek Philippe Celestial 6105G-001 especially important within the Grand Complications collection is the addition of sunrise and sunset indications.
Mechanically displaying sunrise and sunset times is considerably more difficult than displaying standard calendar information because those times constantly shift throughout the year based on Earth’s axial tilt and seasonal positioning.
The 6105G-001 calculates those changes mechanically using a dedicated cam-based system calibrated specifically for Geneva’s geographic latitude.
This allows the watch to continuously display changing daylight patterns across the calendar year without requiring electronic assistance.
For collectors of astronomical watches, this represents a significant advancement.
Even more impressive is the way Patek Philippe engineered the adjustment system. Astronomical watches are traditionally difficult to correct because modifying one indication can disrupt the synchronization of others. The Celestial 6105G-001 has been developed to allow time adjustments while maintaining harmony between civil time and astronomical displays.
That engineering discipline is where the watch truly separates itself from many high-complication pieces.
A Bold Modern Case Design
The Celestial 6105G-001 also introduces a noticeably more contemporary aesthetic than many traditional Patek Philippe Grand Complications.
Crafted in white gold and measuring 47mm, the case features an integrated lug structure with engraved detailing along the flanks and a highly architectural profile. It feels more sculptural than classical — a surprising direction for a brand often associated with conservative elegance.
And yet the design works.
Rather than relying on vintage nostalgia, the watch embraces a modern technical identity that complements the complexity of the astronomical display.
The large dimensions are necessary to accommodate the layered sky chart system, but the integrated case construction helps distribute visual weight effectively on the wrist.
This is not a discreet dress complication.
It is a statement piece designed for collectors who appreciate mechanical artistry as much as traditional refinement.
Inside The Caliber 240 C LU CL LCSO
Powering the Patek Philippe Celestial 6105G-001 is the self-winding Caliber 240 C LU CL LCSO, an evolved version of the manufacture’s ultra-thin micro-rotor movement architecture.
The movement coordinates multiple astronomical calculations simultaneously, including:
Sidereal time
Rotating sky chart
Lunar orbit
Moon phases
Sunrise indication
Sunset indication
Despite the complexity, the micro-rotor construction allows the movement to remain relatively slim while preserving the elegant proportions expected from a Patek Philippe Grand Complication.
The movement also incorporates the brand’s advanced regulating technologies, including the Gyromax balance and Spiromax balance spring, helping ensure long-term precision and reliability.
More importantly, the movement demonstrates what Patek Philippe does best: combining extraordinary mechanical complexity with refinement rather than excess.
Nothing about the watch feels unnecessarily theatrical.
Every indication serves a genuine horological purpose.
Why The Patek Philippe Celestial 6105G-001 Matters
Luxury watchmaking in recent years has largely revolved around heritage-inspired designs and incremental updates to established icons.
The Celestial 6105G-001 takes a very different approach.
It is ambitious, unconventional, highly technical, and unapologetically niche.
That is precisely why it stands out.
Rather than revisiting archive references or leaning on nostalgia, Patek Philippe has created a watch that explores new territory within modern astronomical watchmaking while still maintaining the finishing standards and mechanical legitimacy collectors expect from the manufacture.
The watch reminds collectors that innovation in haute horlogerie does not always need to be louder.
Sometimes it simply needs to be smarter.

Final Thoughts
The Patek Philippe Celestial 6105G-001 is more than a complicated watch.
It is a mechanical interpretation of astronomical motion — a watch that transforms the changing sky, lunar cycles, and shifting daylight patterns into something wearable through pure mechanical engineering.
That alone makes it remarkable.
But what elevates the watch further is how coherent the entire experience feels. Despite the technical density of the movement and display system, the Celestial remains balanced, refined, and unmistakably Patek Philippe.
In an era where much of luxury watchmaking is driven by familiarity, the 6105G-001 feels refreshingly ambitious.
Just ahead of the Mid-Autumn Festival, when the moon is at its brightest, TUDOR unveils its first ever watch with a moon phase complication… and some magic from Jay Chou.
The Moon occupies a special place in Eastern lore: in the Chinese tradition of the Mid-Autumn Festival, it symbolizes togetherness and the unity of family. It was the most fitting occasion to harness the creative energy from TUDOR’s own family, particularly the multi-talented Jay Chou, to create the first ever moon phase watch in the collection.
The subtle sophistication of the 1926 line was the perfect place to start. This line is named after the year when “The Tudor” was first registered as a brand on behalf of Rolex founder Hans Wilsdorf. It captures and stays true to TUDOR’s philosophy, representing both beauty and value. Working with TUDOR’s designers, Jay added his magic to the watch, and the result is as magnificent as a resplendent full moon lighting up the night sky. Framed by a perfectly polished bevel, the moon phase indicator appears at 6 o’clock on three brand new dials in 39mm stainless steel cases for the 1926: Blue, Black and Jay’s own, champagne-colour. The moon phase indicator for each dial is distinct, and Jay’s vision for the champagne-colour dial model has come to life in a truly fantastical way, with the phantom moonlight gold disc representing the moon hidden behind an inky black cutout that slowly disappears as the moon waxes and wanes.
In Roman mythology, Luna the goddess personifies the divine beauty and magical mystery of the moon. Most years have 12 full moons that appear once during a lunar cycle lasting roughly 29.5 days, but our calendar doesn’t necessarily sync up perfectly, so some years might see 13 full moons. This is what makes the moon phase complication so mesmerizing – the watch measures our 24-hour days right down to the very second. Meanwhile, it also measures a completely different cycle – the lunar cycle. Not only can you tell the time, but you can also tell when it’s time to… watch out for werewolves.

TUDOR 1926 IS “BORN TO DARE”
Since its founding in 1926, TUDOR has endeavoured to produce the best possible watches at the best possible price. This mission, bold then as it is now, is inspired by the vision of the brand’s founder Hans Wilsdorf. The inventor of several cornerstones of modern fine watchmaking – wristwatch precision, waterproofness and the self-winding mechanism – Wilsdorf dreamed of devising a watch that was technically perfect while remaining affordable and so created the TUDOR brand to bring his dream alive. The 1926 models form part of this uncompromising heritage, promising their future owners no less than the best possible quality at the best possible price. Made from a block of one of the most robust stainless steels in existence, 316L steel, and
highlighted with touches of satin-brushed rose gold, the case on these models is waterproof to 100 metres (330 feet) thanks to its screw-down crown and case back. The movement, the pinnacle of Swiss watchmaking expertise, is finely decorated despite not being visible, and is adjusted to the highest chronometry standards in the watchmaking industry. The hands and embossed dials are crafted by the most meticulous professionals in the field. Finally, the metal bracelet stands out thanks to the quality of its design, manufacturing and finish. All these things and more come together to produce the famous TUDOR quality, a philosophy summarized by the brand’s signature, “Born To Dare” – always striving to do better.
The 1926 Dial Points to Tudor’s Legacy
The dials of the 1926 model are a fine example of TUDOR’s thorough attention to detail. Domed for a vintage touch, the delicate design points to TUDOR’s origins. These dials have applique even-numbered Arabic numerals between faceted arrow-shaped hour markers. The wealth of detail on the dials of the 1926 line creates a striking and intricate play of light that perfectly complements the sword-shaped hands with their matching colours, and the moon phase indicator is a novel touch that adds a bit of poetry to the watch.
The Tudor Metal Bracelet
The metal bracelet has taken pride of place in TUDOR design from the very beginning. Much more than a mere accessory, it is an integral part of the brand’s aesthetic and practical heritage. The 1926 line naturally has a purpose-made bracelet designed with comfort, refinement and quality in mind. Made up of seven links of varying sizes, it closely follows the curve of the wrist. Its outer links are satin-brushed while those in the middle are polished – a variety of finish that enhances the elegant appearance of the watch. Meticulously assembled in accordance with TUDOR’s longstanding skill in the field, the bracelet is flexible as well as strong.
The Tudor Guarantee
Since its creation by Hans Wilsdorf in 1926, and in line with his vision of an ideal watchmaking product, TUDOR has never stopped producing the most robust, durable, reliable and precise watches in existence today. Bolstered by this experience, and confident in the knowledge of the superior quality of its watches, TUDOR offers a five-year guarantee on all its products. This guarantee does not require the watch to be registered or any periodic maintenance checks to be performed and is transferable should the watch change ownership during coverage. TUDOR also recommends that its watches should be serviced approximately every 10 years depending on the model and the extent of its use on a day-to-day basis.

Armin Strom has unveiled a new limited edition of its game-changing Gravity Equal Force timepiece with a striking off-center Jungle green dial featuring a hand-guilloche pattern. The independent Swiss luxury brand will produce only 15 pieces of the eye-catching watch.
Created to stand out, the newest interpretation of the epic Gravity Equal Force timepiece features an off-center Jungle green dial. Its dial’s guilloche pattern was created by Kari Voutilainen, the Finnish watchmaker who is also a close friend of the brand. The pattern’s horizontal lines appear in harmony with the three characteristic horizontal bridges of the Gravity Equal Force timepiece, which are visible on the movement side.
A matt black PVD-coated movement plate offers a stark contrast to the Jungle green dial, highlighting its luminosity. It also complements the other visible movement parts – the barrel and the micro-rotor and the polished screws and jewels. The ASB19 movement and the steel hands are developed and manufactured by Armin Strom and are meticulously hand-finished in-house.
Presented in a 41 mm stainless-steel case, the Armin Strom Gravity Equal Force Jungle Green comes with a black alligator strap with black stitching, which underscores the stark contrast between the watch’s Jungle green dial and its black plate.
Groundbreaking technology, riveting design and craftsmanship that characterize every Armin Strom watch distinguish this timepiece. First launched in 2019, it is the world’s first automatic watch with constant force transmission, which results in consistent power delivery to the balance. In short, it means that the watch always delivers flawlessly constant precision. Its ASB19 caliber offers a power reserve of 72 hours. The Gravity Equal Force’s ASB19 movement includes a “stop work” mechanism that prevents the mainspring from fully unwinding, thus leveraging only the part of the mainspring’s unwinding process that can deliver power most consistently.
This remarkable new Gravity Equal Force timepiece was designed and produced in-house at the brand’s manufacture in Biel. Like every Armin Strom watch, its ASB19 automatic winding calibre has been assembled twice. After its first assembly, the movement is painstakingly disassembled and each individual part is cleaned, dried, reassembled and lubricated before being meticulously regulated, tested, and returned to the case.
The Gravity Equal Force Jungle Green has been released in an edition limited to 15 pieces and will be available from March 2022.
