OYSTER PERPETUAL 'BUBBLEBACK' MODEL, REF. 3372, CASE NO. 488'750, CIRCA 1946

The Rolex Bubbleback, first introduced in 1933 and continued to be manufactured well into the late 1940s, was the subject of countless variations, including a vast array of dial configurations, bracelet and strap options, and different case metals and combinations. Curiously, it saw the use of both automatic and manual wind movements, highlighting the diverse character of its design heritage.

Interestingly, the term 'Bubbleback' refers to the unusually thick construction of the first Rolex cases with an automatic movement, which were made by adding a rotor mechanism on top of pre-existing manual-wind calibers. The distinctive 'bubbled' caseback of the Bubbleback has come to represent a particular stage in Rolex's development. These uncommon and rare watches continue to be a staple for collectors who want to honor Rolex's distinctive design language while owning a model that is rarely seen in the current horological landscape.
