勞力士，罕有，不銹鋼自動上弦鏈帶腕錶，配中心秒針，"Turn-O-Graph"，型號6202，約1954年製

The Turn-O-Graph was presented at the Basel Fair in 1954. 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".

The Turn-O-Graph was available with a black dial, the 'De Luxe Model' featured a "magnificent white 'honey-comb' dial".

Despite its brilliant concept, the model was at the time not as successful as expected by Rolex, but enjoys today great popularity amongst collectors.
