Built on the Polychrono platform, this edition combines skeletonized construction with the visual language of the Sketch series. The dial is opened up to reveal the chronograph structure beneath, while sketch lines remain visible across the surface, referencing the earliest stage of the design process.

The lightweight polycarbonate case maintains the reduced visual weight and tactile feel of the original platform, while the exposed movement, multi-tone crowns, and contrasting hands introduce additional depth, structure, and complexity throughout the watch.
