red sub dial vs service red sub dial.

[Fabrice M]

I wanted to get opinions hopefully from savvy collectors:

I have found a Rolex red sub for sell with a service dial. The service dial does have the red SUBMARINER on it with tritium markers, and because it is new(er) the red is very bright, which is nice, the dial looks new, and it is sold by a Rolex dealer, so no issue as far as authenticity.

My question is: is it less valuable and if so by how much? from a similar condtion sub with the original dial.

Thanks.
