The 1815 297.021, seen from the bench

The A. Lange & Söhne 1815 ref. 297.021 is a 40.5 mm yellow gold case watch representing Glashütte watchmaking heritage. It features the in-house L1924 manual-wind caliber with power reserve indication, silver dial with Arabic numerals, and thin dauphine hands with an off-center small seconds subdial at six. The 18 mm lug width is standard for this dress watch model. The sapphire caseback reveals the three-quarter platinum plate with hand-engraved details, gold chatons, and blued screws characteristic of the manufacture movement.
