Rolex 620 Description

The Rolex Caliber 620 was a workhorse automatic movement of the “Big Bubbleback” era from the mid-1940s to early 1950s. As a key member of the 10.5”’ 600-series, it was a more robust, integrated, and accurate design than earlier calibers. It was produced in both non-chronometer and “Officially Certified Chronometer” grades and was fundamental in establishing Rolex’s reputation for precision in its Oyster Perpetual line.
