Palmer Grand Complication, movement number 97912, is a unique pocket watch manufactured in 1898 and sold in 1900. This 18k pink gold timepiece features a highly complex caliber incorporating a minute repeater, perpetual calendar, split-seconds chronograph, and moon phases. Collectors value this specific reference for its historical provenance and technical density, as it represents one of the earliest and most complicated watches commissioned by a prominent American industrialist. The watch features a white enamel dial with four sub-dials and a heavy hunter-case construction. On the secondary market, this unique piece occupies a high-six-figure to low-seven-figure price bracket depending on auction demand. A notable auction result occurred in 2013 when the watch sold for $2,251,750, setting a record at the time for a pink gold Patek Philippe grand complication due to its original condition and documented history."}, "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-philippe-97912-2013", "brand": "Patek Philippe", "reference": "97912", "model": "Stephen S.
