About This Watch
The A. Lange & Söhne 1815 Chronograph is widely regarded as one of the finest chronograph movements ever made, with many collectors placing it alongside the Patek Philippe 5170 and F.P. Journe Centigraphe at the summit of the art. The caliber L951.5 is a column-wheel flyback chronograph with an instantaneous jumping minute counter, and every component is finished to extraordinary standards. The flyback function allows the chronograph to be reset and restarted with a single pusher press, without the traditional stop-reset-start sequence. Through the caseback, the movement reveals a level of decoration that is almost unmatched: the column wheel is visible and polished to a mirror finish, the chronograph levers are elaborately engraved, and every surface receives appropriate decoration. The 39.5mm rose gold case and argenté dial with railroad minute track, blued steel hands, and pulsometer scale at the periphery create a presentation that is classically medical-instrument aesthetic. Named after the birth year of Ferdinand Adolph Lange, the founder, the 1815 collection embraces classical watchmaking values. This chronograph is the watchmaker's choice: technically perfect, aesthetically traditional, finished beyond reproach.
