Antique Pocket Watch Key, Size 7 | Hope Bros & Co. Ltd. Shanghai Signed

This authentic antique pocket watch key is a fascinating example of a watchmaker and jeweler advertising key signed Hope Bros & Co. Ltd., Shanghai. Designed for use with key-wind and key-set pocket watches, this Size 7 key dates from an era before stem-wind mechanisms became the standard. Such signed keys served both as practical watch accessories and as promotional items for prominent jewelers and merchants.

Hope Brothers & Co. Ltd. was one of the leading British-owned retail firms operating in Shanghai during the late 19th and early 20th centuries. The company specialized in fine jewelry, watches, silverware, and luxury goods, serving both the expatriate community and affluent Chinese clientele. A signed pocket watch key from Hope Bros & Co. represents a unique connection to the thriving international trade and commercial activity of Shanghai during its treaty-port era.

Watchmaker-signed keys from overseas retailers are particularly desirable because they combine horological history with international commercial heritage. Collectors appreciate these pieces not only for their association with antique pocket watches but also for the insight they provide into the global watch trade during the Victorian and Edwardian periods.

Whether displayed alongside a key-wind pocket watch, added to a specialized watch key collection, or incorporated into a display of antique advertising memorabilia, this signed Size 7 key offers historical significance and strong collector appeal.
