Collectors value this reference for its 36mm coin-edge case and the caliber 591 automatic movement, which features a solid gold rotor and a retrograde date display positioned at 6 o'clock. The dial is crafted from solid gold with hand-guilloché patterns, featuring traditional blued steel pomme hands and Roman numeral tracks. This reference is noted for its slim profile and its adherence to the aesthetic principles established by Daniel Roth during the brand's late 20th-century resurgence. On the secondary market, the 3218 in white gold typically trades between $25,000 and $35,000 depending on condition and the presence of original accessories. While the yellow gold variant is more common, the white gold execution is produced in smaller quantities, making it a rarer find at international auctions.", "score": 199}, {"slug": "a-lange-sohne-238-032-1815-annual-calendar", "brand": "A.

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.", "score": 84}, {"slug": "mb-f-31r0032", "brand": "MB&F", "ref": "31R0032", "model": "Horological Machine No. 3", "case_material": "18k Rose Gold and Titanium", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/mb-f-31r0032", "description": "The MB&F Horological Machine No. 3 (HM3) reference 31R0032, known as the \"Sidewinder,\" was produced between 2009 and approximately 2012. This reference features a multi-part case constructed from 18k rose gold and grade 5 titanium, housing the Girard-Perregaux based caliber re-engineered by Jean-Marc Wiederrecht. Collectors value this model for its inverted movement architecture, which places the 22k gold battle-axe winding rotor on the dial side, and its twin conical truncated cones that display hours and minutes laterally. The Sidewinder orientation aligns the cones perpendicular to the arm, distinguishing it from the \"Starcruiser\" variant. On the secondary market, this reference typically trades in the $55,000 to $75,000 range depending on condition and provenance. While not a limited edition, total HM3 production remained low, and a unique \"Chocolate\" version of the Sidewinder later appeared as a limited run of 10 pieces.", "score": 72}]}
