Reported Movement and Case Details

Internally, the watch is catalogued as housing a manual-wind calibre L121.1 movement featuring 43 jewels. According to the auction source, the case is equipped with an engraved white-gold hinged cuvette depicting the A. Lange & Söhne family domain that was originally inaugurated in 1873. The seller documentation notes that opening the cuvette reveals a sapphire-crystal caseback through which the movement and a specially engraved balance cock are visible. These internal and reverse caseback features are reported by the cataloguing and are not verifiable from the single primary dial photograph.

Dial Architecture and Visible Features

The watch presents an asymmetric silvered dial layout fitted with blued steel hands and deep blue printing. Time is displayed on an off-centre primary hour and minute subdial accented by Roman numerals and diamond-shaped hour markers, complemented by a subsidiary seconds subdial and an AUF/AB power reserve indicator. At the 2 o'clock position sits an outsize double-aperture date display with blue numerals showing '28'. The watch is fitted with a fluted winding crown bearing the brand signature on the right case side of the 38.5 mm white gold case, and it is mounted on an alligator leather strap paired with an 18k white gold pin buckle.
