The Vintage Wrist Watch Company has dated this piece to the 1890s.
The chain measures 30cm long including the T-bar and the clasp.

The chain comes with a silver swivel fob surmounted by a lion with a ball representing supremacy over the world. The swivel is hallmarked for Birmingham 1899 with a maker’s mark for James Alexander, first registered in 1881. The fob has two stones, bloodstone and carnelian, some surface marking and a small chip to the edge of the bloodstone, but nothing too serious.
The watch and chain come in a new presentation box.
