Object description

Dial and Case Design

The Lange 1, reference 191.028, features a 38.5 mm case crafted from 18k white gold. The design is characterized by an asymmetrical dial layout that places the main time display at the nine o'clock position. Accompanying this are a large date display located near two o'clock and a power reserve indicator positioned at the three o'clock mark, which uses the markers 'AUF' and 'AB' to denote the winding status.

The dial is rendered in a blue color, providing a contrast to the white gold indices and hands. The small seconds dial is situated at the four o'clock position, completing the non-linear arrangement of the display elements. The case is fitted with a leather alligator strap, which attaches to the lugs and is fastened with an 18k white gold pin buckle.
