Lange & Söhne 1815 Annual Calendar reference 238.032 in 18k pink gold was introduced in 2017 and remains in the current collection.

The 40mm case houses a solid silver argenté dial with blued steel hands, Arabic numerals, and a railway-track minute scale characteristic of the 1815 family. Unlike the Saxonia Annual Calendar, this model lacks a panoramic date, opting for a classic pointer-date subdial. On the secondary market, this reference typically trades between $38,000 and $46,000 depending on condition and completeness. A notable technical detail is the inclusion of a hidden button between seven and eight o'clock that allows for the independent adjustment of the moon phase display, which is calculated to remain accurate for 122.6 years."}, "score": 18, "why_compare": "Same a. lange & söhne collector universe; shared search intent: 18k, lange; similar gold case profile.", "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "top_listing": null, "auction_comp_count": 0, "review_url": "https://mostexpensivewatches.net/de/review/a-lange-sohne-238-032-1815-annual-calendar", "alternatives_url": "https://mostexpensivewatches.net/de/alternatives/a-lange-sohne-238-032-1815-annual-calendar"}, {"reference": {"slug": "a-lange-s-hne-912", "brand": "A.

Lange & Söhne Grand Complication reference 425.041 in pink gold was unveiled in 2013 as a limited edition of six pieces, with production spanning approximately one decade due to the complexity of its assembly. Collectors value this reference as the brand’s most complicated wristwatch, featuring the manual-wind caliber L1902. The movement comprises 876 parts and powers a grand and small strike, a minute repeater, a split-seconds chronograph with flying seconds, and a perpetual calendar with a moon phase. The 50mm case is constructed from 18-carat pink gold and houses a multi-part enamel dial. Given its extreme rarity and original retail price of approximately 1.9 million euros, secondary market values typically reside in the high-seven-figure range, though public transactions are rare. One notable production detail is that a single master watchmaker requires one year to assemble and regulate the strike mechanism for each individual piece."}, "score": 18, "why_compare": "Same a. lange & söhne collector universe; shared search intent: hne, lange; similar gold case profile.", "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "top_listing": null, "auction_comp_count": 1, "review_url": "https://mostexpensivewatches.net/de/review/a-lange-s-hne-912", "alternatives_url": "https://mostexpensivewatches.net/de/alternatives/a-lange-s-hne-912"}]}
