How can I confirm authenticity of a 5167A Khaki Strap

[watchwithlove]

Hello everyone

I found a 5167A Khaki Strap for sale
I did not know that there are replica ones out there that look very much alike so I got worried about the authenticity of the one that is for sale.

Is there a way to tell if the strap is original or not?

I found some replica strap pictures online and they do like the real one a lot. The inside markings, Patek Logo, the D38 code etc on the back are all the same. I checked black rubber band on my watch and I did see one difference. I wanted to confirm if that is a tell, and if there are other ones that I can check...


On my authentic black rubber band, when you look at it closely from the side, there is a thin line that goes all through the band. I realized the replica Khaki Band did not have that (that is the only difference I saw)

I asked for the close up images of the band from the seller. I will also post those when I receive them.

This is the thin line I am referring to: (it makes a curve right before it enters the case)



This is the replica band pictures I have found. It matches every detail except that line.






Any info is appreciated
