Lange & Söhne Zeitwerk Decimal Strike Honeygold reference 143.050 was released in 2017 as a limited edition of 100 pieces and is no longer in production. Collectors prioritize this reference for its use of the proprietary 18k Honeygold alloy, which is harder and more scratch-resistant than standard gold, and its unique acoustic complication. Unlike the standard Striking Time that chimes on the hour and quarter-hour, the caliber L043.7 in this model sounds a high-pitched tone every ten minutes to align with the digital jumping numerals. The dial features a silver-white finish with a hand-hammered tremblage bridge. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often fluctuating between $120,000 and $180,000 depending on provenance. A notable auction result occurred in 2021 when a well-preserved example sold for approximately $140,000, confirming its status as a high-value rarity."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "a-lange-s-hne-143-050-2023", "brand": "A.
