Looks like some of the numbers have ozidized. also around the six is a vertical sqaure not a horizontal like the 3 area which is a retanglaur shape. I wonder why some are different in this model. Wondering if this a fake
I got it from the Beverly Hills IWC boutique. it is an IWC oem strap for deployant that is supposed to come with the current top gun chrono (44mm) 21mm width
