They say time is just one dimension. We added two more.
The One Week Manufacture Edition proves that measuring time can be a three-dimensional experience thanks to its intricately crafted mechanical architecture. It’s a ticking exploration of horological depth that can last up to seven days.
Driving this dimension-defier is our ARM21 calibre. It’s a complete reimagining of our first in-house movement and reveals how far scientific design can evolve in just over 15 years. Inside, two barrels work in series to ensure consistent energy delivery for an entire week. Yes, the One Week will run for a week when fully wound. As horological artisans with a scientific foundation, we never over-promise — not even on the names of our products. At its core, finger bridges with clean, geometrical lines hold the two barrels in perfect symmetry, occupying the right-hand side of the movement. The energy is displayed through a power reserve indicator whose mechanism is inspired by the cone system of historical pocket watches. But has been reinterpreted with modern technology.
The One Week Manufacture Edition rejects the conventions of what a watch dial is supposed to look like. Instead, it presents time through a layered architecture of anthracite PVD-coated bridges and plates. Each component is positioned to create a mechanical landscape that reveals new details from every angle. The central hands, mounted on a geometrically sculpted bridge, seem to float above this mechanical terrain with precision. The innovative winding mechanism, placed on the dial side, and the three-dimensional skeletonised power reserve indicator further emphasise this architectural approach. This style extends through the case with its integrated bracelet, creating a seamless flow from the mechanical architecture within to the presence on the wrist.
True to our aesthetics philosophy, which is deeply rooted in the classical craftsmanship of haute horlogerie, each component of the One Week Manufacture Edition undergoes meticulous hand-finishing. Geneva stripes flow across the bridges, while straight and circular graining create subtle shifts in texture. The cone that drives the power reserve indicator is hand-polished, as are the many bevels that catch the light with the highest precision across the timepiece. Among these refined details, the polished ratchet wheel bevels stand out as particularly striking. The frosted mainplate provides the perfect backdrop for its mechanical performance. The hand-decoration on the piece is a testament to our belief that these carefully crafted details are not merely ‘beautiful’ — each decorative technique serves a purpose, and together, they make a watch truly grand.
