The 6202is THE VERY FIRST Rolex watch with a rotating bezel. Considered by many as the base model on which the Submariner, Sea-Dweller, Thunderbird and Yachtmaster were built.
Since I have decided to keep a series of Rolex bubbleback and semi-bubbleback, this 6202 with original gilt dial is a must....
The Turn-O-Graph was presented at the Basel Fair in 1953, the year of production of the present watch. The model was always fitted with a rotating bezel with five minute divisions, referred to as a "time-recording-rim" by Rolex. Designed to be used as a simplified chronograph version for timing events for up to an hour, it was promoted as being able to calculate the "Timing of a transatlantic telephone call, the rate of a machine, a patient's pulse, the speed of a train or the development of a film".
Despite its brilliant concept, the model was at the time not as successful as expected by Rolex, mainly due to the simultaneous in-house competition from the Submariner and the GMT-Master, but enjoys today great popularity amongst collectors.
