Moritz Grossmann TREMBLAGE Green – Limited Edition Watch

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.

The watch features a star-shaped arrangement of seven bridges, radiating from the center like a nebula, giving it both structural integrity and visual depth.

The movement is laid out with four lines of symmetry, aligning the barrels, balance, and small seconds for a harmonious aesthetic.

Technical Excellence: A&S5201 Calibre

Dual barrels provide an impressive 90-hour power reserve.

Components are arranged in a kinematic chain around the edge, enhancing both function and form.

The crown mechanism is inverted and placed on the case-back side for symmetry with the first wheel at 9 o’clock.

Aesthetic Details

The lower levels of the movement are treated with a rich blue PVD, contrasted by palladium-finished bridges and components.

Includes horizontal satin brushing on the dial side and Arnold & Son’s signature ‘Rayons de la Gloire’ motif on the reverse.

The 40 mm diameter and 9.10 mm thickness ensure elegance on the wrist.

Strap & Bracelet Options

Available with a blue alligator leather or rubber strap.

Also offered with a three-link steel bracelet that highlights the watch’s symmetry and skeletonized beauty.

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.
