A. Lange & Söhne's Lange 1 “25th Anniversary” collection reveals its latest piece, a special edition of the Lange 1 Tourbillion Perpetual Calendar. An elegant execution of a highly-complex complication, the new model will retain the color scheme of the previous models with its blue-printed argenté dial, blued hands, and a white gold moon disc with hand-engraved stars. The watch features a 41.9mm white gold case and an L082.1 movement that is decorated with a special motif that is exclusive to the 25th Anniversary editions.
