This reference is distinguished by its 46.2mm case constructed from solid 950 platinum, paired with a silver-plated dial and blue steel hands. It utilizes the IWC manufacture caliber 51612, an automatic movement featuring a Pellaton winding system, a seven-day power reserve, and Kurt Klaus’s perpetual calendar module which displays the year in four digits. Collectors value this specific reference for its significant weight and its position as the first non-limited platinum perpetual calendar in the Big Pilot line. On the secondary market, prices typically range from $28,000 to $38,000 depending on condition and the presence of original documentation. A notable production detail is that while not a numbered limited edition, its high retail price and platinum composition resulted in relatively low production volumes compared to steel counterparts.", "score": 203}]}
