Collectors prioritize this reference for its Lemania-based RD 40 caliber, a manual-wind movement featuring the Geneva Seal and chronometer certification. The 40mm case features a stepped bezel and concave lugs, while the dial typically displays applied Breguet numerals and a leaf-hand handset. Production was strictly limited, often to 28 or 100 pieces per configuration, making it rarer than modern mass-produced equivalents. On the secondary market, these timepieces generally trade between $15,000 and $25,000 depending on condition and provenance. A notable variant includes the monopusher chronograph version, which has achieved higher prices at auction due to its mechanical complexity and historical significance within the early Roger Dubuis catalog.", "score": 198}, {"slug": "a-lange-sohne-datograph-405", "brand": "A.

The movement features a flyback chronograph, a jumping minute counter, and a signature oversized date display. The dial is crafted from solid silver with a black galvanized finish and rhodiumed gold appliques. On the secondary market, this reference typically trades in the low-to-mid six-figure range, generally between $100,000 and $130,000 depending on condition and provenance.

It houses the high-frequency Calibre 400 automatic chronograph movement. As a unique piece, it was created specifically for the Phillips Geneva Watch Auction: X, where it sold for 250,000 CHF. Because only one example exists, it does not have a standard secondary market price range; however, its valuation remains in the mid-six-figure bracket based on its singular auction history.
