ARMIN STROM Gravity Collection: capturing the laws of gravity
ARMIN STROM Gravity is the first watch from the Biel-based Manufacture to feature an
automatic winding mechanism with micro rotor.
With this first series of automatic watches driven by the Manufacture’s new AMR13 calibre,
ARMIN STROM wanted to express the essence of a fundamental law of physics – that of
gravity. Thus, the laws of gravity are used in an automatic watch to transform movements
into a mode of indicating the time.
However, the ARMIN STROM Gravity does not simply provide a glimpse of how this
transformation works, rather, the dial is designed to proudly display the micro rotor, which
captures the power of the movements and transforms them into energy. The visibility of this
mechanism is made possible thanks to an innovative concept of transmission for the rotor,
which remains smaller in size than the diameter of the going barrel.
The ARMIN STROM Gravity collection is available in four colourways that represent the four
elements: FIRE, EARTH, WATER and AIR. The ARMIN STROM Gravity boasts the same
exceptional level of finishing that has contributed to the reputation of the brand and of its
eponymous founder. This is a timepiece that will appeal to connoisseurs of fine watchmaking
wishing to celebrate the movement in all its forms.
