DANIEL ROTH Tourbillon Platinum

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.

Armin Strom extends its golden era with the One Week Skeleton Rose Gold, a new interpretation of its architectural One Week design. This fully skeletonised masterpiece reveals the depths of its mechanics, paying tribute to Mr. Armin Strom’s pioneering artistry in skeletonisation—a craft at the heart of the brand’s philosophy and heritage.

For the first time, the in-house calibre appears in a solid 18K rose gold case, enriching the collection with a warmer character. Rose gold-coloured finger bridges, hands, and applied indexes mirror the tone of the case, while a sleek black textile strap provides a refined modern contrast. Measuring 41 mm in diameter, the case remains compact and ergonomic, while its skeletonised architecture gives the watch a distinctive presence—a harmonious balance of technical craftsmanship and precious metal elegance.

Seven Days of Precision
At its heart lies the hand-wound Calibre ARM21-S, a reinterpretation of Armin Strom’s first in-house calibre. Two mainspring barrels work in series to deliver a steady flow of energy for seven days, wound by two ratchet wheels visible on the dial side—a distinctive Armin Strom signature. Operating at 3.5 Hz, the calibre ensures consistent precision and stability in daily wear.

Inspired by historical pocket watches, the conical power reserve mechanism is complemented by a 3D power reserve indicator, displaying remaining energy with exceptional clarity. Central hours and minutes keep the display symmetrical, while a skeletonised small seconds at 9 o’clock adds an engaging sense of motion.

Transparency in Gold
Every component of the Calibre ARM21-S is decorated by hand, reflecting Armin Strom’s dedication to traditional craftsmanship. Hand-polished bevels, Geneva stripes, circular graining, and finely finished screw sinks demonstrate uncompromising attention to detail. Each One Week is assembled twice—a hallmark of the brand’s commitment to mechanical precision and aesthetic integrity.

Limited to just 50 pieces worldwide, the One Week Skeleton Rose Gold continues Armin Strom’s modern gold chapter—a celebration of mechanical transparency, precision, and craft.

Armin Strom proudly presents the Mirrored Force Resonance Ice Blue, a limited edition timepiece that exemplifies the brand’s dedication to horological innovation and artisanal excellence. With only 15 pieces available worldwide, this release marks a bold evolution in the art of synchronized timekeeping.

The watch features a striking ice blue sunray guilloché dial, crafted using a traditional hand-operated rose engine lathe. Its off-center layout and radiant finish create a captivating play of light beneath the sapphire crystal, while beveled and polished indexes and hands add depth and movement to the design.

At the core of this timepiece is the manually wound Caliber ARF21, a technical breakthrough in resonance watchmaking. Armin Strom’s patented clutch system connects two balance wheels, allowing them to oscillate in opposite directions and synchronize for enhanced precision and stability. Twin seconds counters provide a visual representation of this resonance effect, and a pusher at 2 o’clock resets the counters, offering a clear demonstration of the mechanism’s accuracy.

The movement is hand-finished to haute horology standards, with Geneva stripes, perlage, and black-polished screws visible through the transparent case back. Each watch is assembled twice to ensure both mechanical integrity and flawless finishing.

Encased in a 43 mm stainless steel case and paired with a dark blue Alcantara strap, the Mirrored Force Resonance Ice Blue is a celebration of independent Swiss watchmaking and the science of movement.
