noun: (historical) A chain used to give easier access to a pocket watch in the watchpocket of a waistcoat. The Albert style went to a T-bar finding that tucked into a buttoned buttonhole of the waistcoat. From there a further small length of chain hung, to which the wearer attached decorative charms such as fraternity or lodge symbols. The double Albert was a chain draped between both watchpockets, with the T-bar and pendant chain in the middle.
