Thanks for sharing. Yes, I know what you mean by "maturing" I have a YG with black dial diamonds. (Yup, solid YG for mature wearers indeed. ha!)
While all DDs look beautiful, I did find that with some models, the background dial colors and hand colors were so similar it was difficult to read the time. Not much contrast. Yours is a great example of clarity.
Wear it in good health. The precious metal bug has bitten you.
