Lange & Söhne Tourbillon Pour le Mérite reference 701.007 in 18k white gold was produced between 1994 and 1998 as part of the brand’s initial launch collection. Collectors prioritize this reference for its Calibre L902.0 movement, which was the first wristwatch movement to incorporate a fusée-and-chain transmission system to ensure constant force. The white gold variant is particularly rare, with only 19 pieces produced out of the total 200-unit run across all metals. It features a 38.5mm case, a silver dial with blued steel hands, and an aperture at six o'clock revealing the one-minute tourbillon. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often exceeding $500,000. A notable auction result occurred in 2021 when a white gold example sold for approximately $800,000, reflecting its scarcity compared to the more common yellow gold and platinum versions.", "score": 198}, {"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": 83}, {"slug": "richard-mille-rm27-01", "brand": "Richard Mille", "ref": "RM27-01", "model": "RM27-01 Rafael Nadal", "case_material": "Carbon Nanotube", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/richard-mille-rm27-01", "description": "The Richard Mille RM27-01 Rafael Nadal was released in 2013 as a limited edition of 50 pieces and is no longer in production.

The watch features a silvered guilloché dial with Arabic numerals on the front and a skeletonized reverse side that displays the striking hammers and centrifugal governor. This model represents the first time a minute repeater complication was integrated into the Reverso’s swiveling case architecture.

The white gold model has seen three distinct series: the first series (5270G-001) lacked a tachymeter scale, the second series introduced the \"chin\" at six o'clock, and the third series (5270G-018 and 019) returned to a cleaner dial layout with a tachymeter scale. While the white gold versions are now discontinued in favor of platinum and yellow gold, they remain significant for transitioning the brand away from Lemania-based calibers.
