Three years ago, independent watchmaker Andreas Strehler launched his new brand, Strehler, to present his philosophy and craftsmanship in a more accessible form. The first model, Sirna, was designed as an essential time‑only watch that distilled his precision, expertise, and uncompromising finishing. The second model, Säntis, takes the brand naturally into the realm of complications. Like Sirna, which was named after the town Sirnach, Säntis draws its name from the mountain near Strehler’s workshop, the highest peak of the Appenzell Alps.

World Time Concept & Crown Operation
Responding to a collector’s request and inspired by his earlier Sauterelle Heure Mondiale, Strehler created a world time watch that remains elegant, intuitive, and deeply personal. Säntis uses a Cottier‑style world time display operated entirely by a single three‑position crown—preserving design purity and simplicity. The 40 mm medical‑grade stainless‑steel case blends refinement with ergonomics and stays below 10 mm thick even with the added mechanism.

Titanium Dial & Time Zone Display
The titanium dial features a sculptural three‑dimensional texture, individually machined, engraved, and hand‑polished. Its pattern is adapted from a design created with Eric Giroud for Sirna. Surrounding it, the 24‑hour ring marks day and night and rotates once per day, aligning with a fixed city ring listing 24 time zones. Central European Time is indicated by “Strehler” rather than a city, and DST‑observing cities are marked with a sun symbol. Both the city disc and 24‑hour disc use luminous printing, with additional luminous dots along the minute track.

Strap, Presentation & Limited Production
The Säntis comes with a subtly grained brown calfskin strap with contrasting off‑white stitching, and other colours are available upon request. Its steel pin buckle is crafted in‑house, echoing the case’s lines. The watch is delivered in a beechwood box with a cognac leather travel pouch. While not limited, production is naturally restricted due to the fully in‑house manufacturing of cases, dials, hands, and movements, resulting in only 30–50 watches per year shared between Sirna and Säntis.

Chronoswiss celebrates three decades of horological mastery with the launch of the Opus Purple Rain, a bold and limited edition chronograph that reimagines the brand’s iconic skeletonized timepiece. Limited to just 30 pieces worldwide, this anniversary edition marks a milestone in modern independent watchmaking, honoring the legacy of the original Opus while pushing the boundaries of design and mechanical transparency.

First introduced in 1995 by Chronoswiss founder Gerd-Rüdiger Lang, the Opus revolutionized the chronograph landscape by exposing its intricate movement architecture on the dial side—a radical departure from the traditionally closed and utilitarian chronographs of the time. The Opus became a symbol of mechanical artistry and a signature of the brand’s avant-garde spirit.

The Opus Purple Rain carries this legacy into the future with unapologetic flair. Encased in Grade 5 titanium and finished with a radiant purple CVD coating, the watch is both lightweight and visually arresting. Its skeletonized dial, also rendered in ultraviolet hues, reveals the ruthenium-coated Chronoswiss C.741S automatic chronograph caliber, offering a 46-hour power reserve and a full suite of chronograph functions including central seconds, 30-minute and 12-hour counters, small seconds, and date.

Adding to its rebellious character is a white UV-reactive leather strap that transforms into glowing purple when exposed to sunlight—an unexpected and surreal tribute to the energy behind this creation. Signature Chronoswiss elements such as the onion crown, coin-edged bezel, and patented Autobloc screw-in lugs remain intact, anchoring the watch in its heritage while embracing a futuristic aesthetic.

“The Opus Purple Rain is not just a commemorative piece—it’s a statement,” said Chronoswiss CEO Oliver Ebstein. “It embodies the spirit of mechanical transparency and innovation that has defined Chronoswiss for 30 years. This is a watch for those who dare to see how far precision and design can be pushed.”

With only 30 pieces produced, the Opus Purple Rain is destined to become a collector’s treasure—a celebration of the past, a vision of the future, and a mechanical theatre on the wrist.

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.

Arnold & Son unveils the Perpetual Moon 41.5 Cliff Grey Edition, a poetic tribute to the cliffs of Cornwall and the legacy of John Arnold, the renowned marine chronometer-maker. This limited edition of 28 pieces in 18-carat red gold reflects the brand’s deep connection to celestial navigation and English heritage.

The dial is adorned with the exclusive Stellar Rays motif, a textured pattern that plays with light through layered transparent lacquer. Its Cliff Grey tone evokes the misty British coastline, while the moon phase display—among the largest in watchmaking—glows in mother-of-pearl enhanced with Super-LumiNova. Set against a midnight-blue sky, the moon is surrounded by hand-painted constellations, Ursa Major and Cassiopeia, symbols of guidance and exploration.

The case, measuring 41.5 mm in diameter, is sculpted with refined lugs and a slim bezel that opens up the dial to its full celestial display. On the reverse, a secondary moon-phase indicator allows for precise adjustment of the moon’s age.

Inside, the manually wound A&S1512 calibre offers a 90-hour power reserve and tracks lunar cycles with remarkable precision. So accurate is its mechanism that it would take 122 years of continuous operation to accumulate a single day’s deviation from the actual lunar cycle.

Crafted entirely in-house in La Chaux-de-Fonds, the movement is finished with Geneva stripes, blued screws, and circular graining. The watch is completed with a warm grey alligator leather strap and a matching red gold pin buckle.

The Cliff Grey Edition is a refined expression of Arnold & Son’s dedication to craftsmanship, astronomy, and timeless design.
