I guess no one would really know since Chanel just started doing this new Hardware. LV uses Golden Brass and a few of my bags had a bit of tarnishing within about 3 years.thanks all...just curious...if there isn't anymore "W" like halmark 22K thing-y...does it mean the gold will tarnish over some time? funny cos my large flap still have the "W" on the clasp and it's 12 series...anyone could enlighten this matter? thanks again for all the compliments..u all made my day!!
