Lange & Söhne 1815 Annual Calendar reference 238.032 in 18k pink gold was introduced in 2017 and remains in the current collection. Collectors value this reference for its manual-wind caliber L051.3, which features a 72-hour power reserve and a pusher at two o'clock for simultaneous advancement of all calendar indications. 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."}, "listing_stats": {"count": 1, "median": 16500.0, "low": 16500.0, "high": 16500.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7715367977047", "title": "A.
