The 5970P platinum variant was manufactured specifically between 2009 and 2011, marking the end of the reference's production cycle. Collectors prioritize this model for its 40mm case diameter, which bridges the gap between vintage and modern proportions, and the Caliber CH 27-70 Q movement. The platinum version is distinguished by its solid black dial and a single Top Wesselton diamond set between the lugs at 6 o’clock. On the secondary market, the 5970P typically commands prices in the mid-to-high six-figure range, often between $350,000 and $450,000 depending on provenance. A notable production detail is that the 5970P was produced in significantly lower quantities than the yellow, rose, or white gold iterations."}, "listing_stats": {"count": 10, "median": 188975.0,
