I would tend to agree here... I love & own both hardware options but have thought for many years now that there is something.... older about GHW versus PHW. I can't put my finger on what it is, but it does feel more mature to me somehow.
It's a fact that GHW predates phw. Probably due to yellow gold (jewellery) was more traditional for daywear, diamonds were only worn after 8pm and with white metals, and no leather bags for the evening - and especially not 'sporty' exotics.
