The American copper cabochon is CNC-engraved in the United States, hand-patinated in Scotland by The Dial Artist, and assembled in France.
The exposed copper cabochon is designed to change and develop its own patina over time with repeated contact, similar to the Statue of Liberty.
Time is displayed via two ultra-thin sapphire discs, with the hour disc jumping at 6 o'clock and the minute disc moving continuously with a red marker.
The jumping hour aperture at 6 o'clock is enlarged for legibility, featuring numerals designed by typographer Simon Schmidt.
The minute disc has a Super-LumiNova BGW9 peripheral ring that glows turquoise at night.
The watch is powered by a Swiss-made La Joux-Perret G101A automatic movement paired with a patented jumping hour module.
The stainless steel case features alternating polished and brushed surfaces.
Three rubber straps are included: navy blue, red, and white, each with a logo pin buckle.
