The Turn-O-Graph however was soon rendered obsolete in demand by the more functional dual-time zone GMT Master launched in 1954. Production of the 6202 ceased in the early 1960s after a relatively short and limited production making examples harder to come by in todays market. The current example has a highly attractive tropicalised dial which is almost celestial like in the way it fades from gold to black.
