John Nagayama's Essential Guide to Patek Philippe Reference 96 Gets Reprinted
John Nagayama's definitive book on Patek Philippe's reference 96 Calatrava has been reprinted, offering collectors another chance to own what Hodinkee describes as an essential guide to one of the most important dress watches in horological history.
About the Book
Simply titled "96," Nagayama's book has been reprinted with 450 copies released for sale. The book covers the long-lived, miniature (by today's standards) time-only Patek Philippe that has become the framework and measuring stick for essentially every dress watch that has followed.
"One of the deepest wells of information on time-only Pateks has put together a book on a reference that could take a lifetime to study," Hodinkee reported.
Why Reference 96 Matters
The Patek Philippe reference 96 was produced from 1932 to 1973, with approximately 10,000 examples made. The watch has seen renewed interest, driven in part by social media attention and growing acceptance of smaller case sizes around 30.5mm.
Japan, where Nagayama is based, has become a hub for small watch enthusiasts and reference 96 collectors. Nagayama is widely regarded as the foremost authority on time-only Patek Philippe watches.

The Reference 96's Place in History
The reference 96 is considered one of the most important dress watches ever made. Its 30.5mm case size was standard for its era but is considered small by modern standards. The watch features hundreds of dial variations and was produced in six potential case materials, including two-tone configurations.
A steel, black-dial, long-signature example of the reference 96 sold at Sotheby's for $200,000, demonstrating the premium placed on rare configurations.
