Rolex cal 3135 powered the Submariner, GMT-Master II, and Datejust for over three decades and is one of the longest-running in-house calibers in the industry. The Parachrom hairspring and Glucydur balance give it magnetic resistance and shock performance well ahead of its era. It was replaced by the 3235 in 2015 but remains the caliber in millions of watches on the secondary market.
