About the Armin Strom System 78 Collection


Serge Michel and Claude Greisler co-founded the modern Armin Strom. Launched in 2020, the ‘78’ in the System 78 collection stands for the year the co-founders were born in. The Armin Strom System 78 collection was born out of the Armin Strom manufacturer's desire to offer Haute Horlogerie in its purest form, by revisiting some of watchmaking’s core functionalities in innovative and novel ways. Conceived with a contemporary and unparalleled design language while offering immeasurable value to those who seek fine watchmaking with a twist, the collection embodies the horological sensibilities of Claude Greisler and Serge Michel, co-founders of the revitalised Manufacture Armin Strom.

Tribute 1

Armin Strom is known for creating mechanically and aesthetically complex timepieces. With the Armin Strom Tribute 1 series, the watchmaker decided to slightly tone down things. With no open work dials or complex mechanics, the Tribute 1 is a traditional dress watch with a modern design. Armin Strom could not deviate from the avant-garde DNA as the crown is unusually placed at the 2 o’clock marker. Whereas, the dial keeping time is fixed on the top-left corner. What makes this series exciting is the addition of vibrant hues such as Burgundy, blue, green, and black.

Gravity Equal Force

Launched in 2019, the Armin Strom Gravity Equal Force series was launched with a revamped case design and a new calibre with declutch mechanism. The motor barrel design is inspired by pocket watches and offers a rare look to the timepiece. Equipped with the ASB19 movement, the Armin Strom Gravity Equal Force offers a power reserve of 72 hours and the reserve indicator is also placed inside the off-centre dial.

Lady Beat

The first Armin Strom for women, the Lady Beat series incorporates the mechanical complexity of the brand with its in-house movement, the ALA20. Whilst combining the mechanical abilities of the brand, the Lady Beat also incorporates the feminine aesthetics needed for being a perfect women’s watch. Be it the crescent main plate or the off-centre dial, the Lady Beat is a dress watch with horological complexities embedded in it.

Armin Strom System 78


The symmetrical excellence of the Armin Strom One Week First Edition is bestowed by its stellar movement, calibre ARM21. This manual-winding mechanical movement is created in-house with a balanced design and modern architecture. Its configuration of two mainspring barrels stationed side by side on the dial, held by interestingly shaped finger-style bridges garners the most attention, creating a truly spectacular vista on the wrist. These barrels work in series and, along with an oscillating frequency of 25,200bph, provide a continuous and consistent power supply for one whole week, i.e. 168 hours. A discreet, conical-shaped power reserve indicator resides at 11 o'clock to display and monitor the calibre's outstanding running autonomy. 

Calibre ARM21 is composed of 35 jewels and 195 parts, and it boasts advanced hand-finishing on the plates and bridges, featuring Cotes de Geneve stripping, straight and circular graining, and polished bevels.
