the.com/watch fob

The leash that proves your watch had a life before wrists existed.

means A short chain or strap attached to a pocket watch, used to secure it and pull it out of the pocket, often dangling a small ornament.

from From 'fob,' a small pocket—likely related to German dialect 'Fuppe,' meaning pocket—that appeared in English in the 1600s for the little pouch sewn into trousers to hold a watch. The chain or strap used to fish the watch back out borrowed the same name, so 'fob' drifted from the pocket itself to the thing dangling from it.
