1941 Rolex Oyster Perpetual Bubbleback 3131 18k Rose Gold WWII Era Vintage

Available for purchase is a¬†1944 Rolex Oyster Perpetual “Bubbleback,” reference 3131, powered by¬†movement number N3****. This example features a¬†solid 14K rose gold Oyster case, a warm alloy used by Rolex during the 1930s—1940s, and is paired with its¬†original Rolex 18K Swiss Made rose gold bracelet a rare and highly desirable surviving configuration.

Produced during the height of World War II, this early automatic chronometer represents one of the most historically significant chapters in Rolex development. The “Bubbleback” designation refers to the domed screw-down caseback engineered to house Rolex’s pioneering early Perpetual rotor movement, a mechanism that laid the foundation for all future automatic Rolex calibers.

The cream-tone dial with gilt Roman numerals shows even, honest patina consistent with eight decades of preservation. The original leaf-style hands, signed Oyster crown, smooth polished bezel, and correct case geometry all remain authentic to the period.

Condition (Added Section)

This example remains in very good vintage condition, showing honest, age-appropriate wear across the case, bracelet, crown, and bezel. The dial displays untouched natural patina, the crystal is clean for its age with typical vintage character, and the bracelet retains excellent structure for an 80-year-old gold link design. The early Perpetual rotor movement is fully operational, maintaining reliable performance consistent with a properly functioning WWII-era Bubbleback. No over-polishing, no dial refinishing, and no modern replacement parts all period-correct throughout.

A rare surviving rose-gold WWII Rolex Bubbleback historically important, mechanically strong, and carrying the unmistakable character of an untouched vintage chronometer.
