Collectors value this reference for its integration of a perpetual calendar and a split-seconds chronograph within a 39mm 18k yellow gold case featuring hinged lugs. It utilizes the caliber 79251, which is based on a Valjoux 7750 modified with Richard Habring’s simplified rattrapante module and Kurt Klaus’s synchronized calendar system. The dial includes a four-digit year indicator, a moon phase, and four sub-dials. On the secondary market, this reference typically trades between $12,000 and $18,000 depending on the presence of the original box and papers. A notable production detail is that the perpetual calendar is programmed to function until 2499, though the century slide must be replaced by a watchmaker when the year 2100 arrives."},
