Arnold & Son unveils the final chapter of its Constant Force 11 collection with the Constant Force Tourbillon 11 Platinum Edition, a limited series of just 11 pieces. This exceptional timepiece celebrates 260 years of horological heritage, paying homage to the legendary friendship between John Arnold and Abraham-Louis Breguet.

Crafted in platinum (Pt950), the 41.5 mm case houses a dial of hand-guilloché tremblé engraving in 18K yellow gold, inspired by the fern-covered moors of Tintagel, Cornwall—Arnold’s birthplace and the mythical land of King Arthur. The white opal subdial and visible constant force mechanism add depth and elegance.

Powered by the A&S5219 manual winding calibre, the watch features a constant force mechanism, one-minute tourbillon, and true-beat seconds. The engraved plate reads: "To the revered memory of John Arnold and Abraham-Louis Breguet. Friends in their time, legendary watchmakers always."

Known for bold evolutions of mechanical wristwatches and daring designs, Chronoswiss unveils its latest creature: the ReSec Snake. Slithering between heritage and rebellion, this timepiece is a hypnotic blend of color, contrast, and kinetic energy — proof that modern mechanical watchmaking still has a few fangs to bear.

The Snake’s Bite

The ReSec Snake coils into view within a 42mm titanium case, coated with a mesmerizing color-changing PVD-coating that shifts from emerald green to turquoise, depending on the light. It’s not just a case — it’s iridescent armor, capturing the reptilian allure of a serpent in motion. Paired with a contrasting white rubber strap, the Snake wraps around the wrist with smooth, tactile elegance.

But the true venom lies beneath the sapphire crystal. A green CVD-coated dial, hand-guillochéd in the Lucerne Atelier, pulses with depth and hypnotic texture. It’s a dial that doesn’t just tell time — it seduces it.

Take a closer look, and the architecture reveals itself: the iconic 3D regulator layout of the ReSec series slithers across the dial, framed by green hour and minute rings and a retrograde second display, like the flick of a serpent’s tongue. Underneath, the exposed gear train glimmers in contrasting tones — a mechanical exoskeleton that moves with silent precision.

Fangs Beneath the Surface

Powering this cold-blooded beauty is the Chronoswiss Manufacture Caliber C.6005, featuring a 55-hour power reserve, ruthenium-plated finishing, and a radial Côtes de Genève motif. It’s mechanical watchmaking at its sharpest: sleek, silent, and engineered to strike.

Limited. Lethal.

Only 100 pieces of the ReSec Snake will ever exist — a rare breed for collectors with a taste for the untamed. The ReSec Snake is a statement: of daring, of detail, and of defiance — proving once again that at Chronoswiss, we don’t follow rules. We shed them.

Greubel Forsey has officially released the Nano Foudroyante, a groundbreaking timepiece that blends cutting-edge nanomechanics with refined craftsmanship. Limited to just 22 pieces, this watch marks a major milestone for the brand, evolving from its earlier Experimental Watch Technology (EWT) concept into a fully developed and independent creation.

The Nano Foudroyante is crafted entirely in white gold and features a rhodium-finished dial with a blue minute track, blued steel hands, and a white foudroyante dial for enhanced legibility. A blue textured rubber strap completes the look, giving the watch a modern and sporty edge.

What sets this timepiece apart is its use of nanomechanics—a revolutionary approach that allows the foudroyante complication to operate using just 16 nanojoules of energy per jump. That’s 1,800 times less than traditional designs. The complication divides each second into six parts, with a red-treated hand rotating once per second, driven directly by the balance wheel. There’s no traditional gear train, just a series of ultra-efficient, low-inertia wheels.

The Nano Foudroyante also features Greubel Forsey’s first flying tourbillon, with the foudroyante dial always facing twelve o’clock for easy reading. Despite its complexity—428 components in total—the movement fits into a compact 37.90mm case, making it the smallest Greubel Forsey watch ever made.

This release is a bold statement of innovation and intent, offering collectors a rare opportunity to own one of the most advanced mechanical watches ever created..
