Do you by chance have 1 or more cheaper/lesser watches laying around you could just harvest some springbars from thier straps?
Just an idea
Also, most stores that sell replacement bands/straps (like Walmart, or Target) have a new set of springbars included inside the package. Packages are labeled with the size, so buying any 18mm strap should have a set of springbars that would work, just buy a cheap one if you have no use for the strap/band.
