Introduction This auction presents an antique Lonville mechanical pocket watch with a 900 silver case, marked “0.900” on the inside of the case back. The dial is signed “Lonville” and features a traditional white dial with large Arabic numerals, blued-style hands and a small seconds sub-dial. The watch has a classic early 20th-century pocket watch design, with a silver case, manually wound movement and an elegant antique appearance. This piece is suitable for collectors of antique Swiss pocket watches, Lonville timepieces, silver-cased watches and early mechanical horology. Historical / Era context Lonville is historically connected with the Langendorf Watch Company of Switzerland. Langendorf Watch Company was founded in 1873 in Langendorf, Switzerland, and became one of the important Swiss watch manufacturers of the late 19th and early 20th centuries. The company later became especially known for the Lanco brand, but it also used and supplied watches under other names connected with its production and export history. The Lonville name is associated with this Langendorf tradition. Historical references indicate that the Lonville brand was abandoned in the early 1950s, when Langendorf increasingly focused on other brands, especially Lanco. Because of this, original Lonville-signed antique watches are best understood as pre-1950s pieces. Based on the design of this pocket watch, including the white enamel-style dial, small seconds sub-dial, manual winding movement and 0.900 silver case, this example is best described as an early 20th-century antique pocket watch, likely from the 1900s to 1930s period.
