A. Lange and Söhne Zeitwerk 147.025

The A. Lange & Söhne Datograph reference 147.025 is a notable iteration within the Datograph Up/Down series, distinguished by its white gold case and blue dial. This particular configuration offers a distinct aesthetic compared to other metal and dial combinations available in the Datograph lineup, appealing to collectors seeking a specific visual presentation of the flyback chronograph complication. It represents a refined evolution of the original Datograph concept, integrating enhanced functionality and a contemporary color palette. This Datograph features a white gold case measuring 41mm in diameter. It houses the manually wound L951.6 caliber, which provides a power reserve of 60 hours. The movement is visible through a sapphire crystal case back, allowing for appreciation of its intricate finishing. The dial is presented in a deep blue hue, providing contrast for the chronograph subdials and the signature outsize date display. As a Datograph Up/Down, this reference appeals to collectors who value a sophisticated flyback chronograph with a power reserve indicator. The white gold and blue dial combination positions it as a more contemporary choice within the Datograph family, offering an alternative to the more traditional silver or black dial variants. Its production reflects A. Lange & Söhne's commitment to combining traditional watchmaking with modern design sensibilities.
