I have several pocketwatches that I wear with my kilt/waistcoat or with my 3-piece suit. But I'm a bit dissatisfied with the chains. So I'd like to buy a couple of replacement chains in different styles, as well as a couple of different endpieces that hook the chain to a buttonhole or to another pocket. I'm not even sure what all the different endpiece options are.

Does anyone have links to a good source to buy these things in traditional styles? Any recommendation on a conservative style? I don't mind spending a little money on this, but don't want to go overboard on price.
