A primary technical advancement for this reference is the proprietary interchangeable strap system, allowing for tool-free changes. On the secondary market, this model typically trades between $24,000 and $30,000 depending on condition and completeness. While the black dial is the standard configuration, this 2021 generation also launched with khaki green and navy blue dial variants featuring matching rubber straps."}, "score": 28, "why_compare": "Same audemars piguet collector universe; shared search intent: audemars, oak; similar steel case profile.", "listing_stats": {"count": 1, "median": 26000.0, "low": 26000.0, "high": 26000.0, "brands": 1, "merchants": 1}, "top_listing": {"id": "h_6615815684179", "title": "Audemars Piguet Royal Oak Offshore Diver | 15710 | Steel", "brand": "Audemars Piguet", "model": "Royal Oak Offshore Diver | 15710 | Steel", "reference": "15710", "price_usd": 26000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/Audemars_Piguet_RO_Offshore_Diver_Steel_A_Collected_Man_London_14.jpg?v=1632241677", "detail_url": "https://mostexpensivewatches.net/listing/h_6615815684179", "buy_url": "https://mostexpensivewatches.net/out/h_6615815684179", "available": false}, "auction_comp_count": 0, "review_url": "https://mostexpensivewatches.net/ja/review/audemars-piguet-15720st-royal-oak-offshore-diver", "alternatives_url": "https://mostexpensivewatches.net/ja/alternatives/audemars-piguet-15720st-royal-oak-offshore-diver"}, {"reference": {"slug": "audemars-piguet-26574st-royal-oak-perpetual-calendar", "brand": "Audemars Piguet", "ref": "26574ST.OO.1220ST.02", "model": "Royal Oak Perpetual Calendar", "case_material": "Stainless Steel", "url": "https://mostexpensivewatches.net/reference/audemars-piguet-26574st-royal-oak-perpetual-calendar", "description": "The Audemars Piguet Royal Oak Perpetual Calendar reference 26574ST.OO.1220ST.02 was introduced in 2015 and remains in production as a core component of the manufacturer’s high-complication catalog.

It houses the self-winding caliber 5134, an ultra-thin movement based on the historic caliber 2120, which includes a 52-week indicator displayed via a central hand pointing to the outer chapter ring.

The 39mm stainless steel case maintains the \"Jumbo\" proportions but lacks a leap year indicator on the dial, a characteristic of early generation perpetual calendars.
