If you are going to pay top price charged by Phong.. I would ask for some corrections.
1. I personally think the CG can be worked a bit more, as it's too fat currently as it sits
2. I don't like the "1665" engraving between the lugs, as it's not reminiscent of any iteration I've seen. Rolex engraving font style changed with the era... 60's, 70's and 80's. So the fonts needs to match with the serial. Phong can do better, I've seen better
3. The top gasket didn't make an appearance on the case until after 5 mil serial. so make sure the serial is after 5 mil
Here is a 5 mil serial engraving
Here is a 3 mil engraving
