Introducing the Armin Strom Gravity Equal Force Ultimate Sapphire Blue

JULY 18 2025    |    Novelties

Armin Strom, the independent Swiss watchmaker renowned for its openworked designs and mechanical innovation, proudly unveils two striking new additions to its System 78 collection: the Orbit Lime Green and Orbit Ice Blue.

These limited edition timepieces—each restricted to just 20 pieces worldwide—introduce vibrant new fumé dials that blend bold aesthetics with technical mastery. The Lime Green model radiates energy and modernity, while the Ice Blue version offers a serene and sophisticated presence. Both dials feature a gradient effect that transitions from vivid color at the center to deep black at the edges, enhancing the visual depth of the openworked design.

A World-First Date Display on Demand

At the heart of both models lies the Armin Strom Manufacture Caliber ASS20, the world’s first movement to feature a date display on a ceramic bezel that appears only when activated. A pusher at 10 o’clock engages the date hand, which points to the current date and advances automatically at midnight. A second press returns the hand to its neutral position, offering a playful yet practical complication powered by a column-wheel mechanism.

The movement also incorporates Armin Strom’s patented Equal Force Barrel, delivering consistent energy for a stable 72-hour power reserve.

Haute Horology Craftsmanship

Each Orbit model is meticulously hand-finished at Armin Strom’s Manufacture in Biel/Bienne, employing traditional techniques such as anglage, perlage, and circular graining. The off-center dial is paired with rhodium-coated hands enhanced with Super-LumiNova®, ensuring legibility and elegance. The watches are housed in a stainless steel case with a fixed ceramic bezel and come with a matching bracelet featuring a double-folding clasp.

The Science of Movement

Founded in 1967 and revitalized in 2009, Armin Strom continues to push the boundaries of horological innovation. Every timepiece is designed, developed, and assembled in-house, reflecting the brand’s commitment to transparency, craftsmanship, and mechanical excellence.

To mark the 16th anniversary of the manufactory, Moritz Grossmann presents the limited-edition ENAMEL ROMAN Vintage

Black is the absence of light. This is the physical definition of a colour that is synonymous with classicism and elegance. At Moritz Grossmann, black is used to form stylish contrasts and also serves as a testament to the highest standards of craftsmanship. The limited-edition ENAMEL ROMAN Vintage, for example, has an enamel dial whose manufacture presents multiple challenges. With this, Moritz Grossmann has chosen the occasion of its 16th birthday to once again shine the spotlight on the expertise of the ateliers and workshops in Glashütte.

Tradition requires renewal, otherwise it remains stagnant in the past and cannot survive. This is an approach that Moritz Grossmann has embodied since 2008: the manufactory opened 16 years ago as a tribute to one of the most exceptional personalities in the history of watchmaking in Glashütte. Moritz Grossmann was an innovative watchmaker and, with the founding of the German Watchmaking School in Glashütte, influenced a generation of artisans.

His values and vision now live on in the Moritz Grossmann manufactory, which crafts a small but exquisite collection of sophisticated watches that always remain true to the standards of the man who gave the manufactory its name. Characteristics of these timepieces include exclusive manufactory movements with innovative details that are designed, made and finely decorated in-house in the company’s own workshops. The highest of standards also come into play when finishing the watches, as impressively demonstrated by the special model marking the 16th anniversary of the manufactory.

Arnold & Son introduces two new editions of its world time masterpiece: the Globetrotter 42 Steel in Strand Blue and Greenwich Green. These timepieces combine technical innovation with refined British design, offering a modern interpretation of global travel.

The Globetrotter 42 Steel features a 42 mm stainless steel case and a rotating 3D globe representing the Northern Hemisphere. The globe is held in place by a hand-finished steel arch bridge with a ruby center, while the dial showcases sunray-brushed continents and polished oceans in either deep blue or rich green.

- World time functionality with 12 reference cities
- Dual time display with 24-hour and 12-hour rings

Constant Force Tourbillon 11, yellow gold edition - A celebration of watchmaking ingenuity

The 41.5 mm diameter Constant Force Tourbillon 11 watch in 18-carat yellow gold, released by Arnold & Son as a limited edition of 11, is driven by a hand-wound mechanical movement. Equipped with two barrels to give a 100-hour power reserve, this timepiece was entirely developed and built at the manufacture in La Chaux-de-Fonds. It is fitted with a constant force mechanism visible on the enamel dial and is regulated by a tourbillon that can be seen on the back. The architecture of this calibre is inspired by that of the timekeeping instrument driven by the first tourbillon created by Abraham-Louis Breguet in 1808, based on a chronometer movement designed by John Arnold. This first tourbillon regulator, now in the British Museum, was given to John Roger Arnold by the Paris-based watchmaker in honour of his scientific collaboration and friendship with his father. The Constant Force Tourbillon 11 timepiece, designed to mark the end of the 260th anniversary celebrations of John Arnold’s legacy, pays tribute to the watchmaker’s ingenuity and his close association with Abraham-Louis Breguet.

The greatest watchmakers of the Age of Enlightenment often knew each other. Some of them exchanged views and appreciated each other despite language barriers and political obstacles. And this was the case with John Arnold and Abraham-Louis Breguet. These two watchmakers, undoubtedly the most productive of the second half of the 18th century, forged a friendship that nothing could shake, not even the throes of war between the two countries or the French Revolution. Aware of their respective talents, during Abraham-Louis Breguet’s frequent trips to London between 1789 and 1791, they shared their views and knowledge of the principles of timekeeping, furthering the science of timekeeping, which in their eyes definitely knew no frontiers.
