The A. Lange & Söhne Datograph reference 403.032 is a significant early iteration of the Datograph line, distinguished by its flyback chronograph and outsize date complication. This reference, introduced in the late 1990s, established the Datograph as a cornerstone of Lange's modern era, showcasing a unique blend of technical innovation and classical Saxon watchmaking aesthetics. It represents the initial vision for a highly legible and functionally robust chronograph from the brand. This particular reference features an 18kt rose gold case with a diameter of 39mm and a thickness of 12.8mm. It houses the manual-wind caliber L951.1, known for its intricate finishing and column-wheel flyback chronograph mechanism. The movement provides a power reserve of 36 hours. A scratch-resistant sapphire crystal protects the silver dial, which is characterized by its prominent outsize date display at 12 o'clock and subsidiary dials for continuous seconds and 30-minute counter. The 403.032 appeals to collectors interested in the foundational pieces of A. Lange & Söhne's contemporary revival, particularly those who appreciate the original design language and technical specifications of the Datograph. Its relatively compact dimensions for a chronograph of its complexity, combined with the rose gold and silver dial configuration, offer a classic yet distinctive presence. This reference predates later Datograph iterations with extended power reserves, marking it as a specific point in the model's evolution.
