Introducing the Armin Strom Gravity Equal Force Ultimate Sapphire Blue

JUNE 25 2025    |    Novelties

We are thrilled to announce the launch of the Armin Strom Gravity Equal Force Ultimate Sapphire Blue, a masterpiece of Swiss horology that combines technical innovation with glacial elegance.

Design & Aesthetics

The watch features a 41 mm stainless steel case and an off-center transparent sapphire crystal dial with a subdial. The main plate, crafted by Kari Voutilainen, showcases a stunning glacial blue guilloché pattern. The color palette of silvery greys and soft blues is inspired by the serene beauty of Swiss glacial lakes. The watch is completed with a blue nubuck leather strap with ice blue stitching.

Movement & Mechanics

Powered by the proprietary Caliber ASB19, the Gravity Equal Force Ultimate Sapphire Blue is the world’s first automatic movement with a patented stop-work declutch mechanism and Geneva cross. This ensures consistent torque and precision across a 72-hour power reserve. The movement is visible through both the front and back sapphire crystals, and features hand-finished components with perlage, Geneva stripes, and circular graining.

Craftsmanship

Each watch is assembled twice to ensure reliability and refinement. Every component is hand-finished in Biel/Bienne, emphasizing traditional techniques and an open-worked design.

Brand Philosophy

Armin Strom celebrates Swiss horological tradition and innovation. Founded in 1967 and revitalized in 2009 by Claude Greisler and Serge Michel, the brand is known for exposing movement mechanics on the dial side. Their motto, “The Science of Movement,” reflects their dedication to precision and craftsmanship.

Limited Edition

The Gravity Equal Force Ultimate Sapphire Blue is limited to just 25 pieces per year, making it a truly exclusive timepiece.

Arnold & Son Perpetual Moon 41.5 Red Gold – Cliff Grey Edition

Arnold & Son unveils the Perpetual Moon 41.5 Cliff Grey Edition, a poetic tribute to the cliffs of Cornwall and the legacy of John Arnold, the renowned marine chronometer-maker. This limited edition of 28 pieces in 18-carat red gold reflects the brand’s deep connection to celestial navigation and English heritage.

The dial is adorned with the exclusive Stellar Rays motif, a textured pattern that plays with light through layered transparent lacquer. Its Cliff Grey tone evokes the misty British coastline, while the moon phase display—among the largest in watchmaking—glows in mother-of-pearl enhanced with Super-LumiNova. Set against a midnight-blue sky, the moon is surrounded by hand-painted constellations, Ursa Major and Cassiopeia, symbols of guidance and exploration.

The case, measuring 41.5 mm in diameter, is sculpted with refined lugs and a slim bezel that opens up the dial to its full celestial display. On the reverse, a secondary moon-phase indicator allows for precise adjustment of the moon’s age.

Inside, the manually wound A&S1512 calibre offers a 90-hour power reserve and tracks lunar cycles with remarkable precision. So accurate is its mechanism that it would take 122 years of continuous operation to accumulate a single day’s deviation from the actual lunar cycle.

Crafted entirely in-house in La Chaux-de-Fonds, the movement is finished with Geneva stripes, blued screws, and circular graining. The watch is completed with a warm grey alligator leather strap and a matching red gold pin buckle.

The Cliff Grey Edition is a refined expression of Arnold & Son’s dedication to craftsmanship, astronomy, and timeless design.

The Golden Era Begins: Mirrored Force Resonance in Rose Gold

Armin Strom proudly unveils a new expression of its horological mastery with the launch of the Mirrored Force Resonance in 18K Rose Gold. This limited edition marks a significant milestone for the brand’s most iconic timepiece, blending technical innovation with timeless elegance.

A First in Rose Gold

For the first time, Armin Strom’s signature case is crafted from 18K rose gold, offering a warm and luxurious aesthetic. The 43 mm case features alternating brushed and polished finishes, enhancing its sculptural presence. Beneath the sapphire crystal, a bold black off-centre dial showcases a handcrafted sunray guilloché pattern, created using a traditional rose engine lathe. A chapter ring with circular finishing adds depth and texture, while a dark grey Alcantara strap completes the refined look.

Resonance Engineered for Performance

At the heart of this timepiece lies the Caliber ARF21, a manually wound movement that exemplifies Armin Strom’s pioneering work in resonance watchmaking. The patented Resonance Clutch Spring synchronizes two independent balance wheels, enhancing precision and chronometric stability. A pusher at 2 o’clock resets the twin seconds counters, offering a visual demonstration of the resonance mechanism’s accuracy.

Craftsmanship Without Compromise

Every surface of the movement is meticulously hand-finished, visible through sapphire crystals on both sides of the case. Techniques such as hand-beveling, black polishing, perlage, and circular graining highlight Armin Strom’s commitment to haute horology. Each watch is assembled twice to ensure mechanical integrity and flawless finishing.

Limited Edition of 15 Pieces

This exclusive release is limited to just 15 pieces, each priced at CHF 88,000. It represents a rare opportunity to own a timepiece that embodies both technical brilliance and artisanal beauty.
A Statement from Claude Greisler

“The introduction of an 18-karat rose gold case marks a significant milestone for the Mirrored Force Resonance series. This choice of material not only enhances the aesthetic appeal but also underscores our commitment to offering a diverse range of options to our clientele,” said Claude Greisler, Co-Founder and Master Watchmaker at Armin Strom.

A timepiece unveiling the aesthetic technique of a finely hand-decorated movement.

For the final titanium 41mm, three-hands limited edition with rubber strap, Romain Gauthier presents a timepiece with a partially open dial, unveiling a portion of the entirely hand-decorated movement.

C by Romain Gauthier Titanium Editions are modern timepieces with a sporty design that encloses a titanium movement whose hand-finishing prowess can be admired on the case-back. This time Romain wanted the stunning features of this movement to be easily visible just by looking at the watch, even when worn. By opening the dial, he reveals the beauty of the mechanism inside, bringing a technical aesthetic to this timepiece, which until now has featured a full dial.


This partially open dial is particularly reminiscent of the history of the brand's very first timepiece, the Prestige HM, which evolved to reveal the seconds-hand mechanism on its sister caliber, the Prestige HMS.

Unveiled in 2021, the C by Romain Gauthier caliber was the result of more than 16 years of know-how acquired through the brand's development and its manufacture, while reflecting Romain's creative freedom with a modern and youthful design.

Technical in nature, casual in style and free in spirit, the Freedom collection has enabled the creation of this contemporary caliber. The significance of C by Romain Gauthier lies in its creative approach to reinforce the notions of continuity with its concept and design, in reference to the Continuum. Reflecting a vision of the future for a timepiece which is part of Romain Gauthier's philosophy, and which opens the door to new horizons.

During its creation, it was clear to Romain that the case had to harmonize with the movement. It had to be contemporary and uncluttered. But not only that – comfort, ergonomics and the choice of materials also contributed to the design of this timepiece with the decision to use Grade 5 titanium. The dial, in sapphire for this edition, adds to the consistency of the piece and evokes a sense of continuity, as no circle completes the time indication.

Inspired by the finger bridges style, the design of the movement follows the watchmaking history of the Vallée de Joux but with a modern approach, reflecting Romain’s vision of the evolution of tradition.

Romain Gauthier presents the sixth edition of the caliber in titanium in a limited edition of 88-pieces and engraved “1 of 88” on the back of each movement.
