Description

The present watch is the A. Lange & Söhne Datograph Perpetual ref. 410.025, a masterful union of high complication, mechanical purity, and the unmistakable architectural beauty for which the Saxon manufacture is renowned. Cased in 950 platinum and paired with a refined rhodié dial, this reference brings together the emotional appeal of a manually wound chronograph with the intellectual sophistication of a perpetual calendar, resulting in one of the most complete and respected modern complications in contemporary watchmaking.

Its 41 mm platinum case, with a thickness of 13.5 mm, gives the watch a reassuring presence on the wrist while preserving the balanced proportions that define the Datograph line. The density and quiet lustre of platinum lend the piece a sense of gravitas, perfectly suited to the complexity within. Framed by a sapphire crystal and complemented by a sapphire caseback, the watch reveals both its restrained dial-side elegance and the extraordinary detail of its movement architecture.

The dial is classically composed yet remarkably information-rich. The outsized date remains one of Lange’s most recognizable signatures, while the perpetual calendar indications are arranged with impressive clarity, displaying the day of the week, moon-phase, and day/night indicator alongside the chronograph registers. Despite the number of functions, the display remains harmonious and highly legible, a testament to the brand’s ability to organize complexity without ever compromising refinement.

At the heart of the watch lies the manually wound Calibre L952.1, a movement of exceptional depth and sophistication made up of 556 parts. Operating at 18,000 semi-oscillations per hour and offering a 36-hour power reserve, it combines a chronograph with perpetual calendar functionality in a manner that is both technically formidable and visually captivating. As with Lange’s finest calibres, the movement is not merely engineered to perform, but also to be admired—its layered construction, finishing, and mechanical choreography visible through the sapphire caseback.

Completed by a black alligator leather strap and a 950 platinum prong buckle, the Datograph Perpetual 410.025 stands as a watch of rare authority. It is at once precise and poetic, analytical and emotional—a platinum chronograph perpetual calendar that captures the very best of A. Lange & Söhne’s watchmaking philosophy.

A.Lange & Sohne – bio

Founded in 1845 by Ferdinand Adolph Lange in Glashütte, Germany.  The company soon became the pioneers in watchmaking in their region.  After Ferdinand’s death his sons, Emil and Richard continued to produce the finest pocket watches of their time.
During World War II, they were victims of bombardments and eventually even got nationalised by the Soviet administration and ceased to exist. At the fall of the Berlin wall in 1990, the grand son of the founder, Walter Lange, revived the company with the help of Swiss watch manufacturers such as IWC & Jaeger-LeCoultre.   The brand introduced their new collection in 1994 with success and by 2000 the company got acquired by the Richemont Group.
