Partially verified

This A. Lange & Söhne Grande Lange 1, reference 115.031, is an upsized variant of the standard Lange 1 model, measuring 42mm in diameter. Dating to the 2000s, it is constructed with a solid rose gold case featuring wide lugs and a smooth domed bezel. The timepiece is characterized by its segregated dial layout, which incorporates time, subsidiary seconds, a power reserve indicator, and the brand’s archetypal digital date window. The watch is powered by a manual-winding movement accessible via a sapphire caseback. The multi-tone grey and black dial is accented with applied rose gold indices, a rose gold date window frame, and rose gold lance hands. A quickset date pusher is positioned at the 10 o'clock mark, and the watch is supplied on a Lange-signed black alligator leather strap with a matching rose gold buckle.

Object description

Case and Dial Design

The Grande Lange 1 is housed in a solid rose gold case measuring 42mm in diameter. The exterior is defined by characteristic wide lugs and a smooth, domed bezel. Functional elements include a crown at the 3 o'clock position for manual winding and a dedicated pusher at 10 o'clock designed to adjust the quickset digital date.

The dial layout follows the established Lange 1 design with a segregated display. A multi-tone grey and black background provides contrast for the off-center hours and minutes, the subsidiary seconds, and the power reserve indicator. Decorative elements include applied rose gold indices, a rose gold frame surrounding the large date window, and matching rose gold lance-shaped hands.

Evidence for this section
  • “features a solid rose gold case with those characteristic wide lugs and a 'domed' smooth bezel”
  • “There is a pusher at the 10 o'clock position for operation of the quickset 'digital' date”
  • “multi-tone grey and black dial is graced with appleid rose gold indices, a rose gold frame around the date window, and a matching rose gold 'lance' handset”

Movement and Features

The timepiece operates on a manual-winding movement visible through a sapphire caseback. A notable feature of the caliber is the hand-finished balance cock, a detail consistent with other models in the A. Lange & Söhne range. The watch also displays the brand’s signature 'digital' date window as a primary mechanical feature.

The display incorporates a power reserve indicator positioned on the dial, which is marked with 'AUF' and 'AB' to track the mainspring's energy state. The watch is paired with a black alligator leather strap that carries the A. Lange & Söhne signature, secured by a rose gold buckle.

Evidence for this section
  • “manual-winding movement, which is prominently on display via the sapphire caseback”
  • “hand-hinished balance cocks have become yet another staple found on nearly all Lange models”
  • “Lange 1 also possesses what is both a technical and visual feature that the brand has become synonymous for: the archetypal 'digital' date window”

Provenance and Context

The Lange 1 model was first introduced in 1994 following the resurrection of the A. Lange & Söhne brand by Walter Lange. Since its debut, the model has evolved into the brand's flagship series, manifesting in various configurations of metals, complications, and sizes.

The Grande Lange 1 serves as an upsized iteration of the original 1994 design. While maintaining the formula established at the brand's revival, the Grande Lange 1 incorporates design updates that differ from the earlier mid-1990s production, such as the exhibition caseback.

Evidence for this section
  • “Over the last 30 years, the Lange 1 has without a doubt become the brands flagship model”
  • “The piece that we have here is a 'Grande Lange 1' — an upsized variant of the standard Lange 1”

Open research questions

  • What is the specific movement caliber number used in the ref. 115.031?
  • Does the serial number on the case back match the internal movement serial number?
