This reference is valued by collectors for its combination of a minute repeater and a tourbillon within a 33mm case, a diameter considered small by modern standards. It houses the manual-wind Caliber R TO 27 PS, which features 336 components and is COSC-certified. The platinum version typically features a white vitreous enamel dial with Breguet numerals and a discrete tourbillon visible only through the sapphire crystal caseback. Due to the complexity of the movement, production was limited to an estimated total of a few hundred units across all metals. On the secondary market, the 3939H in platinum generally commands prices between $250,000 and $450,000 depending on provenance and condition. A unique piece in stainless steel set a record for the reference when it sold for 1.4 million CHF at the 2011 Only Watch auction."}, "listing_stats": {"count": 1, "median": 57500.0, "low": 57500.0, "high": 57500.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7516691431511", "title": "Patek Philippe Patek Philippe Annual Calendar Moonphase", "brand": "Patek Philippe", "model": "Patek Philippe Annual Calendar Moonphase", "reference": "—", "price_usd": 57500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Perpetual Calendar", "Annual Calendar", "Moon Phase"], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS11404_40930858_PATEKPHILIPPE_ANNUALCALENDARWGBLUEDIAL_5205G-013--6.jpg?v=1763910931", "detail_url": "https://mostexpensivewatches.net/listing/h_7516691431511", "buy_url": "https://mostexpensivewatches.net/out/h_7516691431511", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7516691431511/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7516691431511/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7516691431511/via/farfetch"}], "available": true}], "auction_lots": [{"slug": "patek-3939-tourbillon", "brand": "Patek Philippe", "reference": "3939H", "model": "Minute Repeater Tourbillon", "case_material": "Platinum", "hammer_usd": 1360000, "year_sold": 2023, "venue": "Phillips Hong Kong", "lot_summary": "Hong Kong-market 3939 (the H denotes Hong Kong delivery).
