About this reference
The A. Lange & Söhne 1815 Rattrapante Perpetual Calendar reference 421.025 in platinum was introduced in 2013 and remains in the current catalog. Collectors prioritize this reference for the caliber L101.1, a manual-wind movement comprising 631 parts that integrates a split-seconds chronograph with a perpetual calendar and moon phase. The 41.9mm case houses a solid silver dial with Arabic numerals and a railway-track minute scale, distinguishing it from the Datograph series. Its technical significance lies in being one of the brand's most complex serial production pieces, winning the Grand Complication prize at the 2013 GPHG. On the secondary market, this platinum model typically trades in the $140,000 to $180,000 range. A notable production variant is the "Handwerkskunst" edition, limited to 20 pieces, which features a tremblage-engraved dial and blue enamel, commanding significantly higher premiums at specialized auctions.
