Hi,
I had the same concern when i first tried the GD on at the AD as my wrist is smaller than yours (6.4 inch) but my heart was set on it so after a few weeks of pondering , i went back to try it again and got it in the end. For some it will look unacceptable due to how thick it is on a smallish wrist but i have no buyer remorse after 2 years and it's my pride and joy among my small collection. It's my weekend watch too and i love the long power reserve from the double barrel.
