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.

Unlike traditional repeaters that chime quarters, this model sounds ten-minute intervals, matching the digital time display. The rhodium-colored dial is made of solid silver with a bridge crafted from black-rhodiumed German silver. While the model remains in the current catalog, production is limited by technical complexity to approximately 30 units per year.

The 41.9mm platinum case houses a solid silver rhodium-colored dial with a moon phase indicator accurate for 122.6 years.

On the secondary market, this reference typically trades between $38,000 and $46,000 depending on condition and completeness.

Lange & Söhne Little Lange 1 reference 111.025 features a 36.1mm platinum case and was produced between approximately 1998 and 2006. Collectors value this reference for its specific proportions, which offer the classic Lange 1 asymmetric dial layout in a smaller diameter compared to the standard 38.5mm model. It is powered by the manual-wind caliber L901.4, featuring a twin mainspring barrel for a 72-hour power reserve and a three-quarter plate made of untreated German silver. The dial is solid silver with rhodiumed gold markers and an outsize date display. On the secondary market, this reference typically trades between $30,000 and $45,000 depending on condition and the presence of original documentation. A notable production detail is that while the \"Little\" designation often implies a feminine target market, the 111.025 is frequently sought by collectors with smaller wrists as a unisex alternative to the original 101.025."}], "reviews": [{"slug": "a-lange-sohne-datograph-405", "lang": "en", "title": "A.
