The original was launched four years ago, featuring a stop-seconds mechanism for the tourbillon with the Zero-Reset time-setting feature – patented mechanisms that allowed the watch to be stopped and then set with one-second accuracy.
With its platinum case and white enamel dial, the new limited edition captures the minimalist aesthetic that has become a hallmark of A. Lange & Söhne watches.
Only 100 have been created and each of the 39.5-millimetre cases is individually numbered. The clean and simple dial is offset by the aperture at 6 which reveals the one-minute tourbillon, suspended beneath a black polished bridge. The calibre L102.1, meanwhile, can be spied through the sapphire crystal caseback.
The brand’s expert in-house team have also engineered a refinement of the intricate filigreed complication by adding two patented mechanisms. First introduced in 1997, the zero-reset mechanism interacts with the stop-seconds mechanism for the tourbillon to assure one-second accuracy when stopping and setting the timepiece.
This elegant watch is completed by a black alligator strap with a platinum clasp.
The 1815 Tourbillon is priced at $197,200.
