The 1815 TOURBILLON by A. Lange & Söhne marks a significant innovation by combining the patented stop-seconds mechanism for the tourbillon with the ZERO-RESET time-setting mechanism for the first time. This pink gold model showcases an argenté-coloured dial crafted from solid silver, adding to its aesthetic appeal and sophistication. With a case diameter of 39.5 mm and a thickness of 11.1 mm, it houses a manually wound movement with an impressive power reserve of 72 hours. Its notable complications include the tourbillon and the zero reset function, making it a remarkable timepiece that exemplifies precision and technical mastery.
