Perpetuum

Perpetuum interprets the continuous passage of time through movement, repetition and classical engraving.

At the centre, acanthus leaves curve symmetrically in a single direction, forming a rotating composition that appears to remain in perpetual motion. Surrounding this central vortex, a crosshatched guilloché field introduces geometric order and visual contrast. Classical hour markers positioned at 12, 3, 6 and 9 o’clock provide four fixed reference points, balancing the fluid energy of the engraving.

Every detail is executed entirely by hand on a copper or nickel-silver dial. Variations in cutting depth, line direction and density create a dynamic interaction with light, allowing the central pattern to appear different as the viewing angle changes.

More than a decorative timepiece, Perpetuum represents the balance between constant movement and enduring order—the two forces through which time is perceived.
