I also agree that I think it depends on the color of the skin. Some skins look better with a cool metal while others look better with warm. The skins undertone will determine which I prefer. However, most of the time I can say I really like GHW.
Here's the bad news, once you get one, you're hooked and you can't stop with there. So, the good news is you'll eventually get both hardware. If you love GHW, get it with black. There's plenty of other colors you can do with PHW. Good luck!!!
I have a silver colored watch also that I always wear. I do have a PHW barenia CDC and it does match nicely when I pair it with other platinum jewelry. However, I just got a gold CDC in rouge and it still looks great with my silver watch! Therefore, I think either color is good...you will probably eventually get both!
