This reference introduced the brand’s first unibody baseplate, machined from NTPT carbon to fuse the caseband and baseplate into a single component for increased rigidity and shock resistance. The 47.77mm case utilizes a combination of NTPT carbon and TPT quartz, featuring a distinct white and black striated aesthetic. It houses the manual-winding caliber RM27-02, a tourbillon movement capable of withstanding 5,000 Gs, originally developed for tennis player Rafael Nadal. While the standard production run was limited to 50 pieces, this specific Only Watch edition is a 1-of-1 prototype. At the 2015 Only Watch auction, this specific timepiece sold for 650,000 CHF. On the current secondary market, standard RM 27-02 examples typically trade in the high-six-figure to low-seven-figure range.", "score": 207}, {"slug": "richard-mille-rm027-01", "brand": "Richard Mille", "ref": "RM027-01", "model": "Rafael Nadal", "case_material": "Carbon Composite", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/richard-mille-rm027-01", "description": "The Richard Mille RM 27-01 Rafael Nadal was introduced in 2013 as a limited edition of 50 pieces, succeeding the original RM 027.

This architecture allows the manual-wind caliber to withstand accelerations exceeding 5,000 Gs while maintaining a total weight of 18.83 grams including the strap. Collectors prioritize this model for its technical advancement in shock resistance and its status as the lightest mechanical tourbillon at the time of its release. On the secondary market, the RM 27-01 typically commands prices between $1,500,000 and $2,000,000 depending on provenance. A notable public sale occurred at a 2023 Christie’s auction, where a specimen achieved a hammer price of approximately $1.1 million, though private valuations often trend higher due to extreme scarcity.", "score": 40}, {"slug": "a-lange-sohne-201-027-saxonia-thin", "brand": "A.
