This is a pocket-watch movement by IWC Schaffhausen dating to 1914, presented in the context of a traditional marriage-watch conversion. The movement’s original construction reflects early 20th-century watchmaking priorities: robust engineering, visible finishing, and parts designed for longevity. As an IWC calibre, cal. 52 carries the maker’s workshop lineage and technical standards from that period. For a contemporary collector or watchmaker the movement offers historical substance for a wrist conversion or study piece, connecting classic mechanical design with modern customisation possibilities.
