Now let’s move onto Rolex case backs, still pre 1995. You can see the Ladies head with a letter G is still present along with the 750 scales hallmark. Here we have a case back from a president from the 80’s (immediately below). (I have circled the hallmarks), below that a 60’s men’s gold datejust case back and then a submariner case back from the 90’s.

Refer to the chart below again as we see some examples of Rolex cases with different purities of gold you can compare them to the chart.
