This reference features the Calibre 12 automatic movement, a successor to the Calibre 11, housed in a tonneau-shaped solid gold case. The \"CHN\" designation specifies a champagne dial with contrasting black sub-dials and a black tachymeter scale. Jack Heuer famously presented these watches to Ferrari drivers, often engraving their names and blood types on the caseback. On the secondary market, prices typically range from $35,000 to $60,000 depending on condition and provenance. A notable production detail is that early versions featured a 12-hour register with all numbers present, while later iterations omitted several digits. Rare examples with documented racing provenance have commanded significant premiums at specialized auctions.", "score": 202}]}
