Langematik Wellendorff Set — 358 Series

When A. Lange & Söhne introduced the Langematik in 1997, it did something few in haute horlogerie dared attempt: it built a self-winding movement worthy of the manufacture's own standards. The L921.4, conceived by Helmut Geyer, one of Lange's earliest employees, was organised around the three-quarter plate with a precision cut-out for a solid gold rotor, and introduced the Sax-0-Mat: a bidirectional winding system running on a ball bearing, a zero-reset seconds mechanism that eliminates the startup delay most hacking watches suffer from, and all of the movement finishing one expects of a Lange. The collection ran for barely a decade before being quietly discontinued. For many who know it, that remains the Langematik's most defining tragedy.

The Wellendorff editions occupy an entirely different tier of rarity within that already rare story. The reference 358.025X here is one of only four pieces ever produced.The pink gold black dial 358.031 is again in single digits, and so is the 358.025 in platinum with silver dial.

Beyond rarity, what is offered here — all six references together, in New Old Stock condition, with original boxes, papers, and solid casebacks is without parallel. The integrated Wellendorff bracelet variants have not circulated on the secondary market in any meaningful way, making their true rarity essentially impossible to benchmark. NOS condition a.comwith solid casebacks means this set has never been worn. As a completepedi, unbroken set from a collaboration that lasted a fraction of the Langematik's already short production run. Once in a lifetime chance to see this together - I am lucky to see it twice. Sold at Langepedia.com
