Collectors target this reference for its 40mm case featuring the signature Malte cross bezel and an integrated bracelet with a hidden butterfly clasp. It utilizes the Calibre 1137, a column-wheel chronograph movement based on the Frédéric Piguet 1185, which includes a large date complication at the 12 o'clock position. This reference is noted for its solid caseback engraved with the Amerigo Vespucci ship, distinguishing it from later sapphire-back iterations. On the secondary market, these yellow gold models typically trade between $35,000 and $50,000 depending on condition and the presence of original documentation. A notable production detail is the guilloché dial pattern, which was specifically designed to provide legibility and texture within the sports-luxury category."}, "listing_stats": {"count": 7,
