A. Lange & Söhne Richard Lange Terraluna Celestial Glass Paperweight

The A. Lange & Söhne Richard Lange Terraluna Celestial Glass Paperweight is a distinctive collectible display object inspired by one of the German watchmaker’s most technically ambitious timepieces. Featuring an intricate astronomical illustration, this circular paperweight captures the visual identity of the Richard Lange Perpetual Calendar “Terraluna,” combining celestial imagery with detailed mechanical watchmaking motifs. Its sculptural form and recognizable Glashütte branding make it an appealing piece of horological memorabilia.

The paperweight features a clear, rounded glass-like construction with a smooth circular profile. One side presents a clean white surface bearing the A. Lange & Söhne name and “Glashütte I/SA” inscription in contrasting dark lettering. The opposite side showcases an elaborate deep-blue celestial illustration featuring the Earth, a crescent moon, and a star-filled sky, surrounded by finely rendered mechanical components, gears, and movement engravings. Cream and silver-grey detailing creates visual depth against the rich blue background, giving the piece an architectural character.

The piece appears well preserved, with its transparent construction, detailed astronomical artwork, and A. Lange & Söhne branding remaining clearly visible. Minor surface marks and signs of handling can be observed under close inspection, while no original packaging is shown. With its distinctive celestial presentation and connection to a significant watchmaking complication, this paperweight makes an interesting addition to a private office, collector's desk, or dedicated horological display.
