Lange & Söhne Datograph Perpetual reference 410.032 in 18k pink gold was introduced in 2015 and remains in the brand’s current catalog. Collectors prioritize this reference for its integration of a column-wheel flyback chronograph with a perpetual calendar and the signature outsize date. It houses the manual-wind caliber L952.1, a 556-component movement featuring a silver-plated dial with solid silver sub-dials and luminous alpha hands. The 41mm case measures 13.5mm in thickness, offering a larger profile than the original 39mm Datograph. On the secondary market, this reference typically trades in the low-to-mid six-figure range, generally between $130,000 and $160,000 depending on condition and provenance. A notable production detail is the rapid-correction pusher at 10 o’clock, which advances all calendar displays simultaneously, a technical distinction from the separate recessed adjusters found on many high-complication perpetual calendars."}, "listing_stats": {"count": 6, "median": 196500.0, "low": 94770.0, "high": 205000.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_7366968213591", "title": "A.
