Return of the Rolex Bubbleback

The Rolex bubbleback has started to regain its popularity with the escalation of the Rolex sports models. For  the early watch collectors, many will know the historical importance of the bubbleback as it was the first fully functional automatic movement in a waterproof case. The variations in dials and caae combination are more interesting that playing with the sports watch bezels, ghost bezels, long E etc, which are print variations owing to different OEM factories producing the bezel inserts.
