A. Lange and Söhne Datograph 140.025

The A. Lange & Söhne Zeitwerk reference 140.025 is a notable variant within the Zeitwerk collection, distinguished by its platinum case and rhodié dial. This reference is part of the initial Zeitwerk series, which introduced a highly innovative mechanical jumping numerals display for hours and minutes, a significant departure from traditional analog timekeeping in a wristwatch. Its design emphasizes legibility and a modern aesthetic while adhering to Lange's traditional standards of finishing and engineering. This particular Zeitwerk features a 41.9 mm platinum case with a thickness of 12.6 mm, housing the manual-winding caliber L043.1. The movement provides a power reserve of 36 hours and is visible through a sapphire crystal caseback. The dial is crafted from solid silver with a rhodié finish, providing a monochromatic and sophisticated appearance. The watch is fitted with a sapphire crystal on the front and offers water resistance up to 3 ATM. For collectors, the 140.025 represents an important early iteration of the Zeitwerk, a model that challenged conventional watchmaking with its digital display. It appeals to those who appreciate mechanical innovation combined with a distinctive design language. The platinum case and rhodié dial variant is considered a classic within the Zeitwerk family, offering a subtle yet luxurious presentation of its complex horological mechanism.
