The launch of the Zeitwerk was a daring and deliberate move by A. Lange & Söhne, designed to spark conversation and, inevitably, controversy. Initially polarizing, it quickly earned its place among the brand’s icons, alongside the Lange 1 and Datograph. The Zeitwerk not only cemented its status within the brand’s legacy but also expanded its appeal to a new audience while remaining true to its loyal collectors.

In 2010, building on the Zeitwerk’s success, A. Lange & Söhne introduced the Zeitwerk Lumen Phantom, a limited edition of just 100 pieces in platinum. Measuring 42mm in diameter, the watch maintains the signature Zeitwerk proportions but adds a distinctive twist. The crown at 2 o’clock, dictated by the movement’s architecture, and the three-part case design—featuring a polished bezel, brushed case band, and polished caseback—create a bold yet harmonious aesthetic. The notched, curved lugs further enhance its exceptional comfort on the wrist.

The standout feature of the Zeitwerk Lumen is its smoked sapphire dial, which allows UV light to charge the SuperLumiNova-coated discs, creating a captivating glow in the dark. This innovation arose from a practical challenge: the original Zeitwerk lacked lume, making it difficult to read at night. The smoked sapphire acts as a reverse sunglass, charging the discs while hidden and ensuring they glow vividly when revealed.

The Zeitwerk Lumen Phantom is far more than a watch—it is a bold statement of innovation, heritage, and design. Its luminous display, technical brilliance, and striking aesthetics make it one of the most daring and celebrated creations in A. Lange & Söhne’s history. Complete with its original accessories, the present example offers a rare opportunity to own this elusive and iconic timepiece.
