CALIBRE 1565

Introduction and Launch: The Rolex calibre 1565, introduced in 1960, is an automatic movement synonymous with Rolex GMT models like the iconic 'Pepsi', integral to the GMT-Master reference 1675, which Rolex produced for over two decades. The calibre evolved from the Rolex 1560 movement, incorporating significant upgrades. Over its production span, the GMT-Master 1675 series saw various iterations, including models equipped with the calibre 1565 and later the enhanced calibre 1575, which introduced the hacking seconds feature in the early 1970s.
