Mechanical Art Transversed: Moritz Grossmann Reveals the BACKPAGE Tremblage Anniversary Edition

The year 2026 marks a historic milestone for the Moritz Grossmann manufactory in Glashütte, celebrating the 200th birthday of its visionary founder and namesake, born on March 27, 1826. A genius watchmaker, scientist, author, and the initiator of the German Watchmaking School, Grossmann profoundly shaped the craft of horology and the fate of his hometown. Rather than merely duplicating historical concepts, the modern manufactory honors his legacy by blending his cutting-edge philosophy with modern engineering. This dedication to technological perfection and exceptional aesthetics cements its place among the world's elite elite watchmakers.

To commemorate this bicentennial occasion, the brand has unveiled its fourth anniversary special edition: the BACKPAGE Tremblage. Debuting on May 19, 2026, this launch presents an exclusive mechanical showcase for collectors—featuring a massive dial opening that reveals the magnificent inner workings of the movement from the front. Crafted with a luxurious three-part platinum case, the watch conceals a subtle celebratory nod on its reverse side: a balance cock delicately engraved with "1826", the birth year of Moritz Grossmann.

At the heart of this timepiece is the hand-wound manufactory calibre 107.0, a technical tour de force that essentially stands as a mirror image of the signature calibre 100.1. To allow components like the Grossmann balance, hand-engraved balance cock, and the triple-band snailing on the ratchet wheel to be admired on the dial side instead of being hidden on the back, the entire movement architecture had to be re-engineered. An additional wheel integrated between the crown wheel and the ratchet wheel reverses the rotation of the drive train, allowing the mirrored escapement and oscillation system to run perfectly in the correct direction.

The defining aesthetic highlight of this model is its German silver dial face, treated with the historic hand-worked tremblage engraving technique. By meticulously guiding a cutter back and forth in tiny trembling movements, master artisans create a vibrant, finely granulated, and uniform matt texture. The remaining dial elements define the watch's character, offered in either an expressive violet or a captivating "blue meteor" galvanized shade, framing the hour display from 11 to 5 o'clock. Strictly limited to 12 pieces per color variant worldwide, the models are completed with matching hand-annealed steel hands and hand-stitched alligator or kudu leather straps.

Chronoswiss Strike Two Stella Blue and Nugget: Where Precision Meets Personality

In the world of independent watchmaking, few designs capture the essence of mechanical artistry and thematic storytelling like the Chronoswiss Strike Two collection. With its signature horizontal regulator layout and exposed gear architecture, the collection is a canvas for both cosmic inspiration and historical homage. The Stellar Blue and Nugget editions, though forged from different visions, share a unified spirit: precision in motion, elevated by craftsmanship.

Architecture of Time

At the heart of both models lies the Chronoswiss Manufacture Caliber C.6000, developed in collaboration with La Joux-Perret. This automatic movement delivers a robust 55-hour power reserve, beating at 4 Hz (28,800 A/h). A skeletonized tungsten rotor, ruthenium-plated Geneva-cut bridges, and polished components reflect the brand’s commitment to mechanical transparency and refinement. Viewed through a sapphire caseback, the movement reveals a radial geometry that echoes the symmetry of the dial above.

The horizontal regulator layout defines the Strike Two identity: a floating hour display at 3 o’clock, central luminous minutes, and a small seconds subdial at 9 o’clock. Two architectural bridges span the dial, exposing the gear train and anchoring the visual rhythm of the watch.

Stellar Blue – A Tribute to Cosmic Velocity

The Stellar Blue edition draws inspiration from the brilliance and motion of stellar light. Its dial features a deep blue CVD-coated base, hand-guillochéd with linear engraving that mimics the trajectory of light through space. A silver rhodium-plated subdial adds contrast, while the luminous minute hand glides across the dial like a comet in orbit.

Encased in matte grey sandblasted stainless steel, the watch offers a futuristic silhouette that complements its celestial theme. Measuring 40 mm in diameter and 12.7 mm in thickness, it wears with elegance and presence. The strap is crafted from white nubuck calfskin leather, lined with blue Alcantara, echoing the dial’s cosmic hue.

Nugget – A Homage to Discovery and Rarity

In contrast, the Strike Two Nugget is a celebration of terrestrial treasure — a mechanical gold rush forged in solid 18ct red gold. Inspired by the thrill of unearthing something precious, the Nugget edition elevates the Strike Two architecture with warmth, weight, and richness.

Its anthracite dial, hand-guillochéd and treated with a galvanic finish, reveals depth and texture. A glossy white lacquered small seconds subdial punctuates the monochrome palette, while the exposed gearwork beneath the hour display adds mechanical drama.

The case, polished and sandblasted, retains the 40 mm diameter and 12.7 mm thickness, but its golden sheen transforms the watch into a statement of rarity. Paired with a black nubuck calfskin strap lined in blue Alcantara, the Nugget balances boldness with refinement..

Two Visions, One Philosophy

Whether inspired by the stars or the soil, the Strike Two Stellar Blue and Strike Two Nugget embody Chronoswiss’s philosophy of independent design, mechanical excellence, and thematic storytelling. Limited to 100 pieces each, these timepieces are not just instruments of time — they are expressions of discovery, crafted for collectors who seek meaning in every detail.

Reinventing the Rhythm of Time: Dominique Renaud Presents the Pulse60

Haute Horlogerie Dominique Renaud (HHDR) marks its official debut with the launch of the Pulse60, unveiled in preview at the Time To Watches fair in Geneva (April 14–19, 2026). This first creation of the new Dominique Renaud brand introduces a radical approach to low‑frequency mechanical watchmaking and expresses the purest form of Renaud’s watchmaking philosophy.

A Vision Rooted in First Principles
Dominique Renaud, co‑founder of the legendary Renaud & Papi manufacture and creator of numerous landmark complications, returns with a renewed focus on foundational movement principles. Guided by the maxim “form ever follows function,” his work embraces clarity, purity and a minimalist, self‑evident aesthetic.
The establishment of HHDR in Tolochenaz brings together a team of watchmakers, designers and engineers in a collaborative, idea‑driven environment. HHDR is conceived as a living laboratory — a place where experimentation, shared expertise and long‑term exploration shape new forms of contemporary horology.

Pulse60 — A New Mechanical Language
At the heart of the Pulse60 is the newly developed BUA2024 movement, which embraces an ultra‑low 1 Hz frequency — just one oscillation per second, echoing the natural rhythm of the human heart. This approach reduces escapement shocks and disturbances, transforming time measurement into a slower, more embodied rhythm.


To master this low frequency, the movement features a monumental 20 mm high‑inertia balance wheel, inspired by marine chronometers. Its large moment of inertia stabilizes the rate by absorbing minute variations in energy and motion.

Dominique Renaud has also completely reimagined the regulating organ, allowing amplitude greater than 360° without knocking, with a theoretical range reaching approximately 700°. This unprecedented freedom greatly improves static rate stability by allowing the balance to follow its own natural dynamics over a longer portion of its oscillation.

 

A Design That Expresses Its Mechanics
The Pulse60’s innovative mechanics are reflected in its seamless, fluid architecture:

- A domed crystal with no bezel
- Lug‑less construction and integrated strap
- Three‑part case structure
- Diamond‑cut or guilloché dial details
- A patented offset regulation system placed outside the balance wheel, offering a completely unobstructed view of the slow‑beating 1 Hz oscillator

The display includes an hour‑minute dial at 12 o’clock, a natural dead half‑second at 9 o’clock, and a torque indicator at 3 o’clock. The caseback reveals a minimalist composition of circular and linear forms, framing the openworked escapement line and double‑roller assembly.

Constant Force Tourbillon 11, yellow gold edition - A celebration of watchmaking ingenuity

The 41.5 mm diameter Constant Force Tourbillon 11 watch in 18-carat yellow gold, released by Arnold & Son as a limited edition of 11, is driven by a hand-wound mechanical movement. Equipped with two barrels to give a 100-hour power reserve, this timepiece was entirely developed and built at the manufacture in La Chaux-de-Fonds. It is fitted with a constant force mechanism visible on the enamel dial and is regulated by a tourbillon that can be seen on the back. The architecture of this calibre is inspired by that of the timekeeping instrument driven by the first tourbillon created by Abraham-Louis Breguet in 1808, based on a chronometer movement designed by John Arnold. This first tourbillon regulator, now in the British Museum, was given to John Roger Arnold by the Paris-based watchmaker in honour of his scientific collaboration and friendship with his father. The Constant Force Tourbillon 11 timepiece, designed to mark the end of the 260th anniversary celebrations of John Arnold’s legacy, pays tribute to the watchmaker’s ingenuity and his close association with Abraham-Louis Breguet.

The greatest watchmakers of the Age of Enlightenment often knew each other. Some of them exchanged views and appreciated each other despite language barriers and political obstacles. And this was the case with John Arnold and Abraham-Louis Breguet. These two watchmakers, undoubtedly the most productive of the second half of the 18th century, forged a friendship that nothing could shake, not even the throes of war between the two countries or the French Revolution. Aware of their respective talents, during Abraham-Louis Breguet’s frequent trips to London between 1789 and 1791, they shared their views and knowledge of the principles of timekeeping, furthering the science of timekeeping, which in their eyes definitely knew no frontiers.
