stickers on the new watch

[topfuel25]

while browsing at a grey earlier. Happen to notice that some submariners like the hulk or ND come with stickers that are with the white QR code instead of the usual black QR code.

Note that the watches are fully stickered properly just that the sticker with the QR code was in white instead. didn't get to take a picture of it though.

incase anyone is wondering which sticker I refer to it is the usual black QR sticker pictured in the attachment. any cause for concern if the watch is with a sticker QR code in white instead? does it denote something else ?
