Rolex 655 Description

The Rolex Caliber 655, also known as the “Super Balance cal. 9.75,” is a vintage automatic movement produced by Rolex. It is most famously found in the Rolex Reference 6062. The caliber is notable for its triple calendar (day, month, date) and moon phase complications. The “Super Balance” designation suggests a high degree of precision, with evidence of adjustment in six positions. Due to its housing in the rare Reference 6062, the Caliber 655 is a significant and highly sought-after historical movement from Rolex.
