Maybe not for the purists, but.....

put my newly acquired Duchess/Omega bracelet on my Big Blue. Color matches to bezel pretty well:

I not sure it’s my kinda thing…….. I’d probably need to see it on the wrist, before making my decision.
I think maybe it’s more of a proportional issue, than one of colour, as you say the colour match is pretty good.
To my eye the bracelet is too tapered to visually carry the coloured sections, upsetting steel to coloured inset ratio.
A little less taper might look more balanced in this situation.
That taper on a plain stainless bracelet fitted to that watch would be fine, but the visual balance is upset by the addition of the coluered inserts, if they had a little more stainl around them it might be better.
Having said all that……..it’s your watch, and if you’re happy with the combination….. that’s all that really matters!
Who really gives a rats arse what anyone else thinks!
Purists be damned!

Different, but looks good.
