two tone bracelets

I have a Tokyo 2020 (522.20.42.30.01.001) and want to put a two tone bracelet on it. Omega has assured me that the bracelet from the 310.20.42.50.02.001 will fit, though the color match won’t be exact. They want $8000 for the bracelet, which is more than I paid for the watch. Does anyone know the part number for the bracelet and where I can find it used or at a discount? (Not interested in a clone bracelet, I prefer OEM).

I also really like the Seamaster two tone bracelets. Will any of these bracelets fit my Tokyo?

Thanks!
