Collectors prioritize this reference because it was the first Speedmaster to feature an asymmetrical case with integrated crown guards and twisted \"lyre\" lugs, establishing the modern Professional silhouette. It is historically significant as the specific model worn by Apollo 11 astronauts during the first lunar EVA. The watch utilizes the manual-wind Calibre 321 lateral clutch chronograph movement. Key details include a \"dot over ninety\" (DON) bezel and a stepped dial with an applied metal logo. On the secondary market, prices typically range from $12,000 to over $30,000 depending on the specific sub-reference and component originality. A notable production variant is the 105.012-63, which features a double-step caseback and is considered the earliest iteration of the reference, often commanding a premium at auction due to its limited production window.", "score": 198}, {"slug": "urwerk-ur-105", "brand": "Urwerk", "ref": "UR-105", "model": "T-Rex", "case_material": "Bronze and DLC-coated Titanium", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/urwerk-ur-105", "description": "The Urwerk UR-105 T-Rex was released in 2016 as a limited edition of 22 pieces. This reference is distinguished by its hand-patinated bronze top cover, which features a raised, clous de Paris hobnail pattern designed to resemble reptilian scales. The case back is constructed from black DLC-coated titanium and houses the caliber UR 5.02, a self-winding movement utilizing a satellite wandering hour complication. This mechanism employs four rotating satellites, each carrying three hour numerals, which pass along a 60-minute scale. The movement also features dual air turbines on the reverse side to regulate the winding rate. On the secondary market, this reference typically trades between $65,000 and $85,000 depending on condition and provenance. While the UR-105 series was officially discontinued in 2021 with the \"Last Knight\" edition, the T-Rex remains a primary example of the brand's experimentation with textured metallurgy.", "score": 83}]}
