Emmanuel, known as 'quattro' on WatchProSite, offers an unparalleled historical deep dive into Audemars Piguet's Royal Oak pocket watches. His meticulous research uncovers two distinct generations from the 1980s and 1990s, complete with reference numbers, production figures, and rare imagery. This article is essential for collectors seeking to understand a lesser-known, yet significant, chapter in the Royal Oak's storied history.
Here is an overview of the Royal Oak pocket watches that I have been able to identify.
They fall into two generations: the first from the 1980s, the second from the 1990s.
Enjoy and thanks for looking!
Best, Emmanuel
