The Vintage Wrist Watch Company has dated this piece to the 1890s.
The chain measures 33cm long including the T-bar and clasp.

Each of the links has the lion silver mark. The T-bar is not hallmarked although it is silver, probably a later replacement. The clasp is hallmarked but difficult to read the date letter.
The chain comes with a later silver fob hallmarked for Chester 1912.
