I got this nice citizen watch i really like as a gift. Unfortunately i dont have the extra links and cant seem to find any online or at any jeweler. Has anyone seen this type or know where i could look?

to all, i have a few watches that i lost the extra links when i bought them. Now i need the links and can't find them. where do i go to get some links for: Android Croton Invicta extra links? What say you all? Many thanks in advance, Chris
