The Armin Strom brand is an example of how it is possible to be innovative and creative, even bold and daring in some cases, while respecting watchmaking tradition and classic aesthetics.
The evolution of the brand has always been aligned to the philosophy and vision of its founder, with the watch movement always taking centre stage.
Born in 1938 in Lotzwil in the Canton of Bern, Armin Strom was trained as a watchmaker and had his first working experiences in his hometown and in St. Moritz.
Born in 1938 in Lotzwil in the Canton of Bern, Armin Strom was trained as a watchmaker and had his first working experiences in his hometown and in St. Moritz.
Initially focused on restoring old clocks and pocket watches, in 1967 he finally opened a specialized atelier in the old town of Burgdorf, to the northwest of Bern in Switzerland, where he started creating his own timepieces.

His first masterpiece came several years later, in 1981. It was a gold pocket watch, numbered 001, featuring calendar and moon phases with a precious dial made of a blue lapis lazuli. The hand-engraved movement gave evidence of his exceptional manual dexterity and meticulous attention to the smallest details.
The quality of his work was the result of years of apprenticeship and development of his skills in various watchmaking schools and workshops in Bern, Zurich, Geneva and even in Glashütte, the cradle of German watchmaking.

In this time, Armin Strom started to dedicate more time to skeletonizing movements of the past and soon decided to specialize in this complex and fascinating art.
In a skeleton watch (or squelette in French), all the parts of the movement which have no active function for its operation are cut away. The remaining parts are often engraved and decorated.
Armin Strom quickly achieved exceptional results in this field attracting the attention of press and collectors at the 1984 Watch and Jewellery Fair in Basel.
By late 1980s, his collection included more than 20 models. For most of them, the customer had the possibility to request special decorations or customizations performed by the Master himself. He truly had special relationships with his demanding customers, opening the doors of both his workshop and his home to receive them, discuss about watches and better understand their wishes.
In the 1990s, he finally started producing timepieces for women. The first one caused a sensation: the smallest ever hand-skeletonized watch, an achievement that gained him an entry in The Guinness Book of Records.

As a recognition of his mastery in the skeletonizing art, in the early 1990s Armin Strom started receiving several orders by large brands who commissioned him to skeletonize complicated watches.

During these years, Armin Strom was able to create a recognizable style for his creations with his skeletonized movements, dial rings and lips on the bezel as a further way to personalize his watches with the initials of the owner.

In preparation of his retirement, in 2006 Strom sold a 51 percent stake of the newly incorporated stock company - Armin Strom AG - to the entrepreneurs Willy Michel and his son Serge while retaining 49% for himself.
One of the first moves of the new CEO Serge Michel was the appointing of Claude Greisler as the new technical director. Before joining Armin Strom, Greisler was a movement designer at Christophe Claret.
Sharing the goal to transform Armin Strom into a larger watch company capable of combining the values of its founder with series production and worldwide reach, Serge and Claude realized the importance of developing and producing their own in-house movements and, before that, of building up parts production capabilities.

They were well aware that only those who make their own plates, bridges, levers, springs, wheels, pinions and screws can control the production process at all levels and thereby bring a movement from idea to production with the required quality and control.
In 2009 the company moved to a new factory in the watchmaking city Biel making significant investments in the most up-to-dated production machinery and at the end of the same year the first in-house manufacture movement, the hand-wound ARM09, was presented.
The One Week Collection introduced at Baselworld 2010 was the first to be equipped with the new in-house developed and produced calibre. This new line interpreted Armin Strom’s watchmaking tradition of skeletonizing in a modern form raising great consensus.

It was with this model that Armin Strom introduced the Four Elements concept still used today where the Water, Air, Earth and Fire names are associated to different case materials (stainless steel, titanium, black PVD-coated stainless steel and red gold respectively).
Since then, all movements equipping the Armin Strom timepieces are produced in-house, making of the brand a pure Manufacture.
In the development of its timepieces, the Armin Strom brand keeps believing in the same principle that guided its founder: "as an object of fine mechanical art, a hand-finished movement is too good to remain hidden between a watch face and case back".
And, in fact, the brand gives the movement as much exposure as possible with surfaces for numbers, indexes and other features reduced to the minimum. Instead of speaking of dials, Armin Strom uses the term "dial ring" or "reduced dial". This approach has no costs in terms of readability. Instead, it offers a three-dimensional experience to the wearer which can fully enjoy the magic of a mechanical watch movement in action.
Over the years, these dial rings have characterised the design of Armin Strom watches as shown in the picture below.
Another hallmark of the brand is the lip positioned at 6 o’clock on the bezel. Armin Strom developed this additional surface on the case as a way to personalise his watches with engraved initials.
Except for this distinctive detail, the cases of the brand are very classic with the explicit goal to leave the spotlight to the hearth of the watch: the movement.
In 2011, after a long and successful career entirely dedicated to watchmaking, founder Armin Strom decided to retire. He remained a shareholder in the company and an adviser to the master skeletonizers of the brand.
After the launch of two other hand-wound calibres, year 2012 was marked by a major milestone: the development of the first tourbillon movement of the brand. Beating at 2.5 Hz, the hand-wound ATC11 calibre was equipped with a double going barrel delivering a remarkable power reserve of 10 days.
And, after the first in-house automatic movement and a micro-rotor tourbillon in 2013, the Armin Strom company finally realised one of the dreams of its founder with the Skeleton Tourbillon Fire model: the creation of a fully skeletonized tourbillon watch.
The One Week Skeleton, introduced in 2014, exemplified Armin Strom's long-standing expertise in skeletonization and hand engraving. By removing all non-functional parts of the movement and meticulously decorating the remaining components by hand, the brand offered owners a unique window into the mechanics of their timepiece.
In 2019, the Gravity Equal Force debuted as the first model in the System 78 collection, named after the birth year of co-founders Serge Michel and Claude Greisler. This watch introduced an innovative solution to ensure consistent force delivery to the balance, thereby enhancing timekeeping stability.

A major milestone came in 2016 with the launch of the Mirrored Force Resonance, a groundbreaking timepiece featuring a patented dual resonating regulator. Few watchmakers have attempted to harness the resonance phenomenon to enhance accuracy, precision, and rate stability.
Armin Strom not only improved overall chronometric performance but also made this natural phenomenon visible, allowing wearers to observe the two resonant regulators working in harmony.

By building on the traditional stop-works mechanism, Armin Strom developed a stop-works declutch system within the mainspring barrel—marking the first time such a mechanism was incorporated into an automatic movement.
With this model, the small "lip" positioned on the bezel at 6 o’clock was streamlined, making it smaller while retaining it as a signature element of the brand.
Today, Armin Strom is recognised for its distinctive Swiss-German horological identity, characterised by instantly recognisable designs, technical mastery, and exceptional finishing. With an unwavering commitment to innovation and precision, the brand continues to redefine modern watchmaking while staying true to its artisanal roots. arminstrom.com

This reinterpretation featured a newly designed calibre and construction, reaffirming the model's status as a cornerstone of the brand's portfolio. Sporty yet sophisticated, intricate yet legible, the One Week is enriched with immersive details that even the most discerning collectors will appreciate.
The same year saw the unveiling of a new generation of the Mirrored Force Resonance, with redesigned movement, dial, and case offering sleeker proportions while retaining its superior chronometric stability.
Characterised by two balance wheels on the dial side and its a patented dual regulator mechanism, this model offers exceptional precision and rate stability by taking advantage of the resonance physical phenomenon.

Additionally, the innovative Orbit introduced a fresh approach to displaying the date.
Instead of a conventional aperture or pointer hand, the Orbit uses a column-wheel mechanism to activate a date display on the bezel with the push of a button, blending functionality with playful ingenuity.

In 2024, the brand unveiled the Dual Time GMT Resonance, a remarkable model featuring two independent movements housed within a single timepiece. By leveraging the natural phenomenon of resonance, this innovative creation synchronizes two time zones with unparalleled precision—a testament to Armin Strom’s dedication to horological advancement.

Serge Michel and Claude Greisler’s journey began in the workshop of Armin Strom himself in the village of Burgdorf, where they first apprenticed as eight-year-olds. They could not have imagined that one day they would transform a small skeletonisation atelier into a fully-fledged independent manufacture, fulfilling their dream of crafting their own watches.
