Worldtimer Two-Tone Bracelet?

Greetings,

I am new to Omega, just purchased a new green Seamaster Worldtimer and interested in seeing if there are any two tone (gold/stainless) bracelet options out there? Not sure if the bracelet is unique to this model or if I can find better luck searching for bracelets with a more common model that has a compatible bracelet.

Thanks!
