Mesh bracelets for 36mm SMP 300 - 212.30.36.20.01.002?

Hello, I’m looking for a mesh bracelet that fits the 18mm lenght of my mid-size SMP 300. The only Omega ones I could find seem to be late 60s/early 70s bracelets (from japan), but I’m a bit hesitant given their age. Has anyone tried those? Are they the only choice apart from aftermarket brands? Thanks.
