The Rolex Reference 2940 is a vintage Oyster Perpetual “Bubbleback”, produced in the 1940s as part of Rolex’s pioneering efforts in automatic watchmaking. It was one of the early models to feature Rolex’s innovative perpetual rotor system, which allowed for self-winding without manual intervention. This made it a significant step forward in the evolution of wristwatches.

Key Features and Significance:

Bubbleback Case: The rounded case back (hence the nickname “Bubbleback”) was designed to accommodate the thicker automatic movement inside. This was necessary due to the early self-winding rotor mechanism.

Movement: Powered by the Rolex Caliber 620 (or later versions like the Caliber 645), a 10.5-ligne automatic movement that was among Rolex’s first self-winding mechanisms.

Oyster Case: Featuring Rolex’s patented Oyster case, it was water-resistant, reinforcing the brand’s reputation for durability.

Dial Variations: Available in multiple dial configurations, including Arabic numerals, baton indices, and railroad minute tracks, reflecting the aesthetic diversity of the time.

The Rolex 2940 was a crucial model in Rolex’s history, representing the brand’s shift toward modern automatic watches. Today, it’s highly collectible among vintage Rolex enthusiasts due to its historical significance and unique “Bubbleback” design.

The Caliber 645 was a workhorse movement that played a crucial role in Rolex’s development of automatic watches, leading the way for future innovations in the Oyster Perpetual line.
