Le Locle and Tavannes, Switzerland
Family watchmaking roots from the nineteenth century
Henri Frédéric Sandoz established a watchmaking enterprise in Le Locle before helping create the large Tavannes Watch Company in the 1890s. Watches bearing the Sandoz name later appeared across international markets through several branches and licensing arrangements.
Swiss pocket and wristwatches, Tavannes connections, dress watches, sports models, and widely distributed mid-century timepieces.
Calibres, escapements, case construction, water resistance, electronic or quartz development, manufacturing methods, patents, and specialist suppliers.
Service considerations, originality, replacement parts, water-resistance assumptions, safe storage, and details that should be documented before restoration.
