WTB 1257 link, bracelet advice

[Kissarmy]

Hi, I have recently bought a Seamaster automatic, tv dial, I love it but it’s a little snug on the wrist. I am looking to buy a couple of extra links but am struggling to find anything. The bracelet and clasp is 1257/220. Any assistance would be appreciated. Am I solely looking at the used market or is this something that I could go to omega for?
Thanks Ian
