Ssense lists all antiqued hardware as silver hardware. It was a frustrating experience when I was trying to buy my YSL belt from them. I had to look at several different internet sources to see if I was actually buying the one with antiqued nickle hardware. I wanted antiqued nickle hardware, not silver hardware. Thankfully it was the antiqued one. Same thing happened with my YSL card holder from ssense, also listed as "silver hardware".
The antiqued hardware that you have on yours looks like the antiqued hardware on my bags and belts. It isn't heavily aged. It just looks like dulled silver. I just got a brand new YSL Rive Gauche tote that has much more antiqued hardware than the other men's pieces that I have, so I guess it isn't always consistent (depends on the design).
