Reasons to Bid

Introduced in 1999, the A. Lange & Söhne Datograph marked a turning point in modern high-end chronograph design, setting a new benchmark for both mechanical architecture and aesthetic refinement. This example, the Ref. 403.035, represents the first-generation Datograph, housed in a 39mm platinum case that carries a solid, reassuring weight, balanced by its compact lugs and clean proportions. The black dial is instantly recognizable, with the signature Big Date at 12 o’clock and a clear bi-compax layout featuring running seconds at 8:30 and a precisely jumping 30-minute counter at 3:30. White gold Roman numerals, recessed subdials, and a surrounding tachymeter scale contribute to a look that is both composed and technically purposeful. At its heart is the hand-wound Caliber L951.1, widely regarded as one of the most significant chronograph movements of the modern era. Celebrated for its crisp operation, column-wheel architecture, and three-dimensional hand-finished construction almost resembling a small city, it remains a reference point for collectors and watchmakers alike. As the original form of a model that reshaped contemporary chronograph expectations, this first-generation Datograph holds a special place in the history of modern watchmaking.
