Watch chains were commonly used in the past to secure pocket watches. They were typically made of metal, such as gold or silver, and were often quite ornate. Pocket watches were a valuable possession, and watch chains served to keep them safe and secure. Some watch chains even had a spring-loaded clip that would attach to the watch’s belt loop, providing an extra layer of security.
In addition to their practical purpose, watch chains were also considered fashionable accessories. They were often engraved with intricate designs or set with gemstones. Some watch chains were even made of precious metals, such as gold or silver. Today, watch chains are still worn by some people as a fashion accessory, but they are not as common as they once were.
