One of the most popular models of Rolex is the Bubbleback. Launched in 1933, it was also one of the early Rolex models. The creation of this model was a significant event for Rolex because it featured the first Auto-Rotor. The Auto-Rotor signified Rolex’s success in developing a self-winding movement. Today, the Bubbleback is one of the most sought after and collectible wristwatches in the world market because production was discontinued in the early 1960s.How did Rolex Succeed in Creating the Bubbleback?In the 1920s, numerous watch-making companies were trying to create a self-winding movement. They kept attempting to incorporate slight modifications to Harwood’s self-winding watch that featured a no winding stem. However, Rolex was following altogether a different path. It experimented with its existing movements and looked for a new solution to the old challenge. Finally, in 1931, Rolex created the Auto-Rotor movement from an existing Aegler movem pink guitar strap ent (subsidiary seconds Hunter 8-3/4”’). This invention resulted in a “perpetual motion” wherein the winding mass could turn smoothly both clockwise and counter-clockwise and pivot a full 360 degrees on its staff in the center of the movement. In 1932, Rolex patented its first successful self-winding perpetual wristwatch. One year later, the Rolex Bubbleback was introduced into the market. Due to unsuccessful attempts in the past and the resulting skepticism in the public eye, Rolex tried to publicize this new model as “the watch sensation of 1934″.The fascinating historical marker is the watch never had “Bubbleback” engraved anywhere on it, and was never officially designated that title. Instead, it bore “Rolex Oyster Perpetual” just below the 12 o’clock position. How did it come to be known as “Bubbleback”? Well, the answer lies in its bubble-shaped, thicker case back. The thick Auto-Rotor led to an over sized mechanism which needed a thicker case.
