Introduction and Launch: The Rolex calibre 1165, introduced in 1965, is a self-winding movement found in the Oyster Perpetual Date. It was part of Rolex's offerings during the 1950s and 1960s—a period when the brand was cementing its reputation for crafting durable, high-quality timepieces. While Rolex was known for both automatic and manual-winding watches during this era, the latter were often positioned as dressier and more affordable options.
