This is what Rolex SA replied to a customer who sent them his 1675, which had a blueberry insert. Hamburgvintagewatches posted the letter of Rolex, which you can see below. Translation: “Rolex never produced a 1675 reference with An all blue bezel”. I understand that these bezels are worth around 50k$ these days, and that they were always surrounded by doubt. Well, I guess there’s little doubt left... had you guys seen this, what do you think?
