There are two version of the vintage Big bubbleback, the Rolex Ref 6031 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 , using the slightly flatter semi bubbleback movement. Produced in less than 1000 examples from 1950-1952.
I have stopped actively collecting vintage watches for nearly 2 years asI was pre-occupied with my vintage hifi equipment. Latley, I have managed to come across a nice Big bubbleback 6031 and the desire to try to add in the big bubbleback to my bubbleback collection grew. I have managed to find the small bubbleback, the medium size bubbleback, the semi bubbleback but not the Big bubbleback Ovettone. Now, I am eagerly waiting for the arrival of my Ovettone! The bracelet is a later Rolex bracelet..
