which is the right dial configuration for the GMT 16758

[Bernard]

Hi folks,
This is my first entry on this site even though i have been lurking for some time.
The question I have concerns the right dial and the location of the dial posts for a 3075 movement.

I have an 18K GMT 16758 with a service dial and am considering putting on a brown dial. The problem I have is the dial I am considering has the posts set at 6 and 11.15, which I believe is for a GMT 1675.

What should be the correct dial for my watch and what position should the posts be located?

help Please !!!
