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": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "patek-philippe-97912-2013", "brand": "Patek Philippe", "reference": "97912", "model": "Stephen S.
