The seller represents this timepiece as being in very good condition, showing light hairline marks. This auction pertains exclusively to the watch, as the box and papers are not part of the listing.

One of its most captivating features is the retrograde seconds display, where the seconds hand sweeps across a defined arc before instantly snapping back to zero and beginning again, creating a lively mechanical motion that draws the eye every few seconds. This distinctive complication highlights Pierre Kunz’s reputation for unconventional and technically engaging watchmaking, giving the dial constant energy and reinforcing the bold character behind the model’s “Spirit of Challenge” design.
