This piece centers on an IWC Schaffhausen pocket movement from 1929, mounted as a marriage watch in a wrist-sized conversion. The presentation highlights early 20th-century watchmaking proportions and a practical approach to adapting a pocket calibre for modern wear. Powering the watch is the original Calibre 73, a product of IWC’s engineering tradition from the period, now fully serviced for reliable operation. For the contemporary collector, it offers a tactile link to historical manufacture and the thoughtful craft of marrying classical movements with wearable cases.
