Rolex Big Bubbleback collection 勞力士大泡泡背

For the Rolex Bubbleback collector, the Big Rolex Bubbleback collection is a must. 

Broadly speaking, there are several versions of the vintage Big bubbleback, the Rolex Ref 4467 & 6031, 6074, 6075 using the real and thicker bubbleback movement, and the dial wording Rolex Oyster perpetual; and the later Model ref 6105 and 6305 Ovettone, with dial Rolex Oyster perpetual DATEJUST or without Datejust , using the slightly flatter semi bubbleback movement. Produced in less than 1000 examples from 1950-1952. 

For  those who have collected vintage watches from the 1980s-90s, they will know that the Japanese, Italian, Taiwanese and Hong Kong collectors went crazy with these watches back then. 

Lately, these bubbleback prices have slowly escalated back to those early days as many more collectors have started to pay attention to these "smaller" watches.
