Greetings!
The following article is a bit dated (2022), but discusses the number of hours a watchmaker spends creating/assembling/finishing many different brands. The top tier watches have 300 or more hours per watch.
The article breaks down several categories: over 300 hours, 100-299 hours, 30-99 hours; 10-29 hours, and 1-9 hours. Rolex, on average, is toward the bottom, in the 1-9 hour range. I was surprised by many of the results.
15 companies are in the top tier - Philippe Dufour and Roger W Smith among them. Second tier includes A. Lange & Sohne and F.P. Journe. Third tier includes PP, AP, VC. Next tier JLC, GP. “Industrial tier is 1-9 hours, anchored by Rolex, Omega, Panerai, Tudor.
Each category has several additional brand's, each described in the article.
I was frankly not aware of many of the brands in the top category - and after looking up some prices I can see why!
I hope you enjoy the article as much as I did!
