A. Lange & Söhne Grand Complication

About this reference

The A. Lange & Söhne Grand Complication reference 425.041 in pink gold was unveiled in 2013 as a limited edition of six pieces, with production spanning approximately one decade due to the complexity of its assembly. Collectors value this reference as the brand’s most complicated wristwatch, featuring the manual-wind caliber L1902. The movement comprises 876 parts and powers a grand and small strike, a minute repeater, a split-seconds chronograph with flying seconds, and a perpetual calendar with a moon phase. The 50mm case is constructed from 18-carat pink gold and houses a multi-part enamel dial. Given its extreme rarity and original retail price of approximately 1.9 million euros, secondary market values typically reside in the high-seven-figure range, though public transactions are rare. One notable production detail is that a single master watchmaker requires one year to assemble and regulate the strike mechanism for each individual piece.
