Always a favourite, fetter links are ideal for adding some dimension to your stack, and these are not so long that they don't sit on the wrist. 
This is from an Albert chain dating to around 1900, and features stamps for 9.375 (9ct gold) on each link. The dog clip is all in good order, and works well.
