A. Lange & Söhne honors the inimitable Walter Lange with an inimitable special-edition timepiece (and an all-new movement.)

Walter Lange was a horological titan, equal parts technical maestro and visionary businessman. When the Berlin Wall came down, he seized on the opportunity to resurrect his great grandfather’s watch company; within a decade of relaunching, the firm was turning out instant-classic designs and developing superfine mechanical movements.

The felicitously named A. Lange & Söhne Tribute to Walter Lange celebrates the man, who died last year, by debuting an all-new movement. It’s a hand-wound, 36-jewel beauty, which features an independent, stoppable seconds complication. In a nice touch, the caliber name (L1924) and reference no. (297) also point to Lange’s birthday (July 29, 1924).
