Wow, Golden's mom, the same thing happened to me and I too purchased a Cartier stainless (was afraid to replace with similar diamond/gold watch)!
I have always had gold hardware on my bags even tho all my daily jewelry is platinium. Just recently I purchased a pladium hardware bag. I agree with everyone who has said that the hardware should bring out the leather rather than match jewelry. Of course, I do not match my shoes to my bag either.
