Paging through the mastering time Heuer TAG Heuer book I realized that the TAG Heuer Twin Time is actually a re-issue of an original Twin Time Heuer first introduced in the 1955. I have not seen these before and would have to assume they are relatively scarce. I have always been intrigued by GMT watches and was excited to discover that Heuer made a very basic GMT the Twin Time in the 50's. Has anyone seen these for sale, what are the prices on these and what is the case size in mm not including the crown? Was this Heuers answer to the Rolex GMT
