Dominique Buser and Cyrano Devanthey have opted to eschew the annular balance used in their debut timepiece, in favour of a more traditional, free-sprung balance wheel. The duo's team has grown since the release of their initial offering, as well. Doubling in size, two additional watchmakers have joined the fold, David Friedli and Yan Hegelbach, assiduously plying and preserving the application of age-old watchmaking techniques.

Crafted by hand, the influence of the likes of Dufour, Voutilainen, and Rexhepi are evident in both the movement aesthetics of the Fundamentum as well as the level of excellence in the finishing techniques applied.
