Collectors target this reference for its 45mm case crafted in 18k 5Npt red gold, a proprietary alloy with a high copper content and a hint of platinum to prevent oxidation. It houses the in-house P.2003/10 caliber, a skeletonized automatic movement featuring three spring barrels providing a ten-day power reserve, a GMT function with an AM/PM indicator, and a linear power reserve display. The blue sun-brushed dial with sandwich construction distinguishes it from standard black-dialed models. On the secondary market, this reference typically trades between $22,000 and $28,000 depending on the presence of original box and papers. A notable production detail is the sapphire caseback, which showcases the intricate circular graining and skeletonization unique to the \"10\" series movements."}, "listing_stats": {"count": 17,
