Collectors prioritize this reference for its historical significance and the Valjoux-based Caliber 13-130 movement. Of the 281 total units produced, the majority were cased in yellow gold, while approximately 58 examples were executed in 18k pink gold. These pink gold variants often feature \"pink on pink\" configurations with matching rose-toned dials. The case measures 35mm and features square chronograph pushers and a snap-on back. On the secondary market, 18k pink gold examples typically command between $1,200,000 and $2,500,000 depending on dial condition and provenance. A notable production variant includes the rare transition from the \"long\" signature to the shortened \"Patek Philippe\" branding on the dial. In 2021, a pink gold 1518 with a pink dial achieved a sale price exceeding $3,000,000 at auction."}, "listing_stats": {"count": 10, "median": 188975.0, "low": 120000.0, "high": 340000.0, "brands": 1,
