Lange & Söhne Datograph Perpetual Tourbillon reference 740.036 was introduced in 2016 as a limited edition of 100 pieces in platinum. This reference features a black solid silver dial and houses the manual-wind caliber L952.2, which integrates a flyback chronograph, a perpetual calendar with a moon phase, and a one-minute tourbillon visible through the sapphire caseback. Collectors value this reference for its technical density and the inclusion of a stop-seconds mechanism for the tourbillon, a rare feature in high-complication movements. The 41.5mm platinum case houses 729 individual components. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often between $600,000 and $800,000 depending on condition and provenance.

The dial features orange and red accents against a matte black surface with tritium-filled markers. Due to the fragility of early PVD coatings, examples with intact finishes are scarce.
