Introduction and Launch: The Rolex calibre 7140 is a self-winding mechanical movement, entirely developed and manufactured in-house by Rolex. This sophisticated no-date, three-hand movement features a small running seconds subdial, exemplifying Rolex’s commitment to precision and craftsmanship. Debuting on March 27 2023, at Watches and Wonders, the calibre 7140 was introduced with the launch of the Rolex 1908. Notably, the 1908 is among the few Rolex models to feature an exhibition caseback, allowing a rare view of the finely finished movement within. This release marked a significant moment in Rolex’s watchmaking evolution, combining traditional elegance with modern innovation. .
