Hi all,
Much has already been written about the 5230 by our moderator Mark and fellow PurisT utcpluseight, , and many here have commented, mainly positively, about this new reference.
Press release reveals that the "basket weave" guilloche pattern is modeled after a watch in the Patek museum.
Let's start with another photo of the 5230.

Well, here is the museum piece that inspired the 5230.

Below is a side by side of the vintage and new..

A close-up of the original "basket weave" guilloche.

All I can say is that I want to see the 5230 ASAP !
Cheers,
Gordon
