Aircooltime is dedicated to the research, history, and collecting of vintage Patek Philippe, Rolex and other interesting vintage wristwatches. Through original scholarship, archival research, and technical analysis, I explore the watches, people, and design philosophies that shaped some of horology’s most important references.
My work has been featured by Hodinkee and Collectability, with research also referenced by auction houses and other media. Here you’ll find in-depth articles, market observations, historical discoveries, and practical insights for collectors who appreciate the stories behind exceptional timepieces.
Whether you’re an experienced collector or simply fascinated by great watchmaking, I hope you’ll find something here worth exploring.
In addition to publishing research, I also provide independent collector consultations on vintage Patek Philippe and Rolex, including originality, condition, historical context, and market considerations. If I can assist with your collecting journey, I’d be pleased to hear from you.
