Marking a new chapter in Angelus’ Urban Collection of cutting-edge watchmaking, the U21 Tourbillon revisits the singular movement and streamlined design focused on structural optimization. The U21 Tourbillon interprets the uniquely structured movement in a noble metal case, combing the bezel-less carbon fiber central case element with polished and satin-brushed 18-karat red gold lugs, enhancing its visual appeal.

The goal with the U21 Tourbillon is to present the essence of the movement by removing any superfluous material.

What seems to look deceptively simple to achieve requires great artistic vision and engineering prowess. The more material that is removed, the more the structure of the movement has to be carefully calculated to ensure rigidity and sturdiness for a maximum precision.
