Perpetual Moon 41.5 Red Gold – Cliff Grey Edition

Arnold & Son continues to push the boundaries of mechanical artistry with the launch of two new interpretations of its iconic DSTB 42 timepiece. The DSTB 42 Red Gold Mint Green and DSTB 42 Platinum Ascot Blue editions bring a fresh chromatic perspective to one of the brand’s most emblematic complications: the true beat seconds.

A tribute to the marine chronometers once supplied by John Arnold to the Royal Navy, the true beat seconds—also known as “deadbeat seconds”—is a rare and technically demanding feature. Unlike the sweeping motion of a conventional seconds hand, this mechanism causes the hand to jump precisely once per second, echoing the cadence of traditional precision timekeeping.

In these two new editions, Arnold & Son elevates the complication with bold color and refined materials. The Red Gold Mint Green model features a vibrant mint green dial housed in an 18K red gold case, while the Platinum Ascot Blue edition pairs a deep blue dial with the cool elegance of platinum 950. Both dials are grained for a rich, light-catching texture and are punctuated by a white opal subdial for hours and minutes, offset at 5 o’clock.

The true beat seconds mechanism is fully visible on the dial side, supported by three openworked bridges crafted in solid gold—red gold for the Mint Green edition and white gold for the Ascot Blue. The seconds hand travels along a railway track between 9 and 12 o’clock, orchestrated by a dedicated mechanism that mimics the precision of an escapement. The anchor-shaped counterweight, a nod to Arnold & Son’s maritime heritage, adds a poetic touch to the technical display.

Powering both models is the in-house A&S6203 automatic movement, beating at 4 Hz and offering a 55-hour power reserve. The movement is meticulously finished with Geneva stripes, perlage, polished angles, and a 22K gold oscillating weight.

Each watch is paired with a hand-stitched alligator leather strap—green for the red gold version and ink blue for the platinum—and secured with a matching pin buckle. Both editions are strictly limited to 18 pieces worldwide, underscoring their exclusivity and collectability.

With the DSTB 42 Red Gold Mint Green and Platinum Ascot Blue, Arnold & Son reaffirms its commitment to blending horological innovation with bold design. These timepieces are not only feats of mechanical engineering but also vibrant expressions of individuality and craftsmanship.

Independent Swiss watchmaker Armin Strom proudly presents the Gravity Equal Force Ultimate Sapphire Rose Gold, a timepiece that exemplifies the brand’s commitment to horological innovation, artisanal craftsmanship, and visual harmony.

Encased in 18K rose gold, this limited-edition watch features a sculptural movement architecture that plays with tone and texture. A brown guilloché mainplate, rose gold-colored bridges, and a floating off-centre sapphire dial create a refined and coherent composition. The watch is paired with a matte brown nubuck leather strap, adding an earthy elegance to the overall aesthetic.

At the heart of the timepiece is the Caliber ASB19, Armin Strom’s groundbreaking automatic movement. It incorporates a patented stop-work declutch mechanism and Geneva cross within the barrel, ensuring consistent torque delivery throughout its 72-hour power reserve. A micro-rotor enables efficient winding while preserving the symmetry and visibility of the movement — a hallmark of Armin Strom’s design philosophy.

Every component, visible or hidden, is hand-finished to haute horology standards. Techniques such as beveling, straight-graining, perlage, Geneva stripes, and black-polished screws are applied with precision and care. The mainplate features a “grain d’orge” guilloché pattern, crafted by master artisan Kari Voutilainen using a traditional hand-operated machine.

This exceptional timepiece is limited to just 25 pieces per year, making it a rare and radiant statement in the world of independent watchmaking. It is a testament to Armin Strom’s philosophy: Mechanics First. Always.
