Rolex Caliber 3135: The Heartbeat of a Legend
The Rolex Caliber 3135, a certified chronometer movement, stands as the backbone of many iconic Rolex watches, including the famed “Green Submariner” (Ref.116610LV). Evolved from its predecessor, the 1570, the 3135 distinguishes itself with a transversal balance bridge, secured at both ends, enhancing its stability and ease of maintenance.
Key features of the Caliber 3135 include its unique red gears coated with Rolex’s exclusive anti-wear material, the Kif shock absorber, micro-adjustment screws on the balance wheel, and a 50-hour power reserve. Its lineage has extended to include the day-date movement Caliber 3155 and the dual time zone movement Caliber 3185, which further evolved into 3186 and 3187 after updates to the shock absorber and hairspring.
One distinct characteristic of the 3135 movement is its silent automatic rotor, a testament to Rolex’s engineering that utilizes no bearings. The rotor’s weight is described simply as “heavy metal,” not specifying gold or platinum, keeping with Rolex’s reserved communication about their precise internal materials.
As Rolex gradually phases out the 3135 in favor of the newer 3235—a complete redesign featuring a bearing-supported rotor—the 3135 remains a dominant force in Rolex’s movement repertoire. Watches equipped with the 3135 are priced from $5,000 to hundreds of thousands, influenced by the casing material and gemstone embellishments, attesting to the movement’s versatility and enduring legacy.
