A. Lange & Söhne Double Split

About this reference

The A. Lange & Söhne Double Split reference 404.047F in stainless steel was produced in 2013 as a unique piece for the "Kidz Horizon" charity auction. Unlike the standard production models in platinum or pink gold, this is the only known example of the Double Split cased in steel. It features the manual-wind caliber L001.1, the first movement capable of measuring split-time intervals up to thirty minutes. The watch is distinguished by its 43.2mm steel case and a black dial with silver registers and tachymeter scale. Because it is a unique piece, it does not have a standard secondary market price range; however, it sold at Christie’s in 2013 for approximately $500,000. Current valuations for a unique steel Lange chronograph are estimated in the high-six to low-seven-figure range, reflecting its status as one of the rarest watches ever manufactured by the Glashütte firm.
