A. Lange & Söhne Lange 1 Reference 191.028

Partially verified

This A. Lange & Söhne Lange 1, reference 191.028, is a manual-wind wristwatch released in 2017 as part of the manufacturer's "Blue Series." The watch features an 18-karat white gold case measuring a classic profile, paired with a Prussian blue dial. The dial layout is asymmetrical, incorporating an off-center hours and minutes sub-dial with Roman numerals, a small seconds sub-dial, a large outsize date display, and a power reserve indicator labeled "Auf/Ab." The movement, visible through a transparent case back, is a manual-wind caliber featuring a traditional Glashütte three-quarter plate, gold chatons, heat-blued screws, and hand-engraved finishing on the balance cock. The watch is presented on a black leather strap and is documented as a production within the maker's established Lange 1 line.

Object description

Case and Dial Design

The watch is encased in 18-karat white gold, providing a polished aesthetic. This configuration places the main time display, featuring Roman numeral hour markers, to the left, balanced by a small seconds sub-dial on the right.

The dial also includes an outsize date aperture and a power reserve indicator. The overall design prioritizes geometric proportions and clarity, maintaining the aesthetic principles adopted by the brand since the 1990s. The casing is fitted with a black leather strap.
