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.

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.

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.

Drawing inspiration from the natural beauty and architectural heritage of Burgdorf, Armin Strom introduces the Tribute 1 Sandstein, a limited edition timepiece that blends Swiss tradition with modern refinement. With only 50 pieces available globally, this elegant watch pays tribute to the region’s iconic sandstone and the brand’s artisanal roots.

Encased in a 38 mm stainless steel case with alternating brushed and polished finishes, the Tribute 1 Sandstein features a warm sand-toned off-centre dial adorned with a grain d’orge guilloché pattern and Roman numerals. A frosted subdial and matching sand Alcantara strap complete the harmonious design.

At its heart beats the in-house Caliber AMW21, a hand-wound movement offering an impressive 100-hour power reserve. The visible motor barrel, held by a mirror-polished finger bridge, adds a modern technical flair while honoring traditional Swiss watchmaking values.

Through sapphire crystals on both sides, the movement reveals Armin Strom’s signature hand-finishing: hand-bevelled bridges, black-polished screws, Geneva stripes, and circular graining. Each watch is assembled twice, ensuring mechanical precision and aesthetic integrity.
