OP41 - chipped the surface. Rust or corrosion concerns?

[Rahul718]

Hi all,

I have a OP41 which was purchased new. Not sure how it managed to the steel managed to get chipped, but I’d like to get the group’s thoughts. Reference the two images below - I circled one of them to show the chip.

To be clear, I’m fine with scratches and even dings, and this particular chip doesn’t bother me. However, I’m curious if this predisposes the steel to corrosion or rust in the future. I know with cars, once the paint is chipped, it’s best to correct it right away to prevent rust. Is that the same with Rolex 904L?

Does Rolex use 904L steel all the way through or is it just surface level? Would rust be a concern in my situation? I would assume not, since refinishing actually removes material, and that surface would otherwise then be susceptible to rust. But just thought I’d ask here for confirmation.

Thanks
