Collectors prioritize this reference for its 39mm case diameter and 8.1mm thickness, which closely mirrors the proportions of the original 1972 model. It features the self-winding Calibre 2121, a movement notable for its 3.05mm height and historical lineage. In 2012, the design transitioned to the \"40th Anniversary\" layout, moving the AP logo from the twelve o'clock position to six o'clock and introducing the \"Petite Tapisserie\" dial pattern. On the secondary market, prices typically range from $65,000 to $110,000 depending on the production year and condition. A notable variant is the 15202ST.OO.1240ST.01, which remains highly sought after for its blue dial and anniversary specifications. Early \"D-Series\" examples from the early 2000s often command premiums due to their transitional dial configurations and lower production numbers."}, "score": 28, "why_compare": "Same audemars piguet collector universe; shared search intent: audemars, oak; similar steel case profile.", "listing_stats": {"count": 3, "median": 45000.0, "low": 45000.0, "high": 60000.0, "brands": 1, "merchants": 2}, "top_listing": {"id": "h_7549754671213", "title": "Audemars Piguet *Mint* 2015 Audemars Piguet Royal Oak Oak (Ref. 15202ST) W/ Full Set", "brand": "Audemars Piguet", "model": "*Mint* 2015 Audemars Piguet Royal Oak Oak (Ref. 15202ST) W/ Full Set", "reference": "15202ST", "price_usd": 60000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "craft-and-tailored", "merchant_name": "Craft + Tailored", "image_url": "https://cdn.shopify.com/s/files/1/1104/9180/files/Img031256_d688510c-f7c2-428d-88cd-d986a49eb38b.jpg?v=1728689998", "detail_url": "https://mostexpensivewatches.net/listing/h_7549754671213", "buy_url": "https://mostexpensivewatches.net/out/h_7549754671213", "available": false}, "auction_comp_count": 1, "review_url": "https://mostexpensivewatches.net/ja/review/audemars-piguet-royal-oak-15202", "alternatives_url": "https://mostexpensivewatches.net/ja/alternatives/audemars-piguet-royal-oak-15202"}]}
