Re: Please help with this 1675 dial please.

My understanding from research is that: in the late 50's and very early 60's the GMT's came with a "Gilt" Dial. Meaning Gold leaf lettering. Reportedly, this continued until the 4th version of the 1675 came out in the mid-60's. Refer to "Vintage Rolex Sports Models" by Martin Skeet & Nick Urul.
