Collectors value this reference for its oversized 36mm case, which was unusually large for the era, and its use of the Valjoux-based caliber 13VZAH. The construction typically features a stainless steel mid-case paired with 18k rose gold bezels, pushers, and crowns. The dials often feature a two-tone aesthetic with tachymeter scales and baton markers. Due to the extreme rarity of vintage Audemars Piguet chronographs—of which only 307 were made between 1930 and 1950—this reference occupies a significant place in the brand's history. On the secondary market, these watches command prices in the mid-to-high six-figure range. A notable example formerly owned by Giorgio Seragnoli sold at auction in 2015 for approximately 305,000 CHF, serving as the design inspiration for the 2020 [Re]master01 release."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "audemars-piguet-1533-vintage-chronograph", "brand": "Audemars Piguet", "reference": "1533", "model": "Oversized Chronograph", "case_material": "Stainless Steel", "hammer_usd": 300000, "year_sold": 2015, "venue": "Phillips Geneva", "lot_summary": "One of only 285 vintage chronographs made by AP between 1930 and 1950.
