1675 Pepsi Bezel check... think not right

[mutter]

Another bezel question... I bought this watch at a highly reputable auction house.

Looking at the bezel recently, something not quite right about it. Where the red crosses the 18 at the 9 o'clock position looks different to any others I've seen. I have higher quality images and can post a link (if I'm allowed?).

The watch came with a black bezel insert and this Pepsi insert as an extra (makes me think service or not right... and why the auction house didn't list it with the Pepsi bezel installed). 2.9m serial number.

Appreciate other's thoughts here...
