Rolex Bubbleback in Steel ca. 1940s – Serviced and Runs Reference Number: Serial Number: 13520 The “Bubbleback” is a nickname for Rolex’s early self-winding watches, characterized by their distinctive, rounded caseback design that accommodated the thicker automatic movement. Produced between the 1930s and early 1950s, these watches were a significant advancement in watch technology. The nickname “Bubbleback” originates from the protruding, bubble-shaped caseback, which was necessary to house the thicker self-winding movements. The Oyster case, a key feature of these watches, offered water and dust resistance, ensuring durability and practicality. With the self-winding movement, the watch no longer required daily winding, a major innovation at the time. While Bubbleback watches were often crafted from yellow or rose gold (9k, 14k, or 18k), this particular model is made from stainless steel, offering a more robust and accessible option. Today, the Bubbleback is a highly sought-after vintage watch, prized by collectors for its historical significance, unique design, and as a milestone in Rolex’s development of automatic movements. This timepiece has been serviced and is running. It comes on a period-correct genuine crocodile leather strap (aftermarket). With the exception of the strap, all parts are original Rolex. The watch is guaranteed to be genuine.
