Rolex 2235 Movement

The Rolex Caliber 2235 is a self-winding mechanical movement introduced in the late 1980s as part of Rolex’s effort to modernize its smaller automatic calibers. Designed for elegance without compromise, the 2235 brought improved precision, hacking seconds, and a more efficient automatic winding system to Rolex’s smaller watches. Show more
