5402 A Royal Oak
I probably get more inquiries on original Royal Oaks than any other pieces. This is one of the nicest I’ve ever come across. The two-tone are actually harder to find than the steel and nearly impossible in this condition.
As an aside, there are no “A Series” two tone RO’s. They just have a number and no letter. However, the convention has become to call the original series pieces with the logo at 6 “A Series” so I have called it that. This is a very early piece and would be the star of any vintage collection.
