Today, Rolex is most often associated with mid 20th-century tool watches, which have become icons in the world of horology, and are some of the most sought after timepieces by collectors. With model names like GMT-Master, Submariner and Cosmograph Daytona, the demand for these exceptional watches continues to grow, however it is important to remember Rolex was founded in 1905, and since its inception, produced an array of wristwatches with modern designs that were masculine and durable. The brand’s quest for technical excellence is seen throughout their evolution, and in the early 20th century two milestone innovations were introduced, the “Oyster” case introduced in 1926 as a water and dust proof timepiece, and in 1931 their “Perpetual” self-winding movement. The combination of these two produced the “Oyster Perpetual”, which has been the backbone of their production ever since.

Rolex patented the first automatic movement with a winding rotor that rotated 360 degrees upon a centrally located pivot. Fixed on an existing movement with the rotor spinning on top, the domed caseback allowed for extra space for the rotor, leading this watch to be nicknamed "Bubbleback". These timepieces became a huge success throughout its production period, from the early 1930s to the 1950s. The present watch is a wonderful example of the reference 3130 "Bubbleback", and preserved in exceptional, hardly-worn condition and fitted with its original Rolex Oyster crown.

This "Bubbleback" is from the second half of the 1940s, and consequently, one of the last generation of the model's production run. It is characteristic for this batch to see the serial number engraved by Pantograph, a technique newly introduced by Rolex after World War II. "Bubblebacks" have an important place in the history of Rolex and this rare, beautifully preserved, 14 karat pink gold reference 3130 has a presence and charisma that is sure to attract collectors.
