After launching the Micrograph, the first 1/100th of a second timekeeping instrument in 1916, and later the Microtimer in 1966 which was the first wrist-worn 1/1000th of a second timekeeping instrument, TAG Heuer pursues its quest for innovation by incorporating timing to within one thousandth of a second within a wrist chronograph. However, watch connoisseurs will need to be patient, since this model is still only at the state of a Concept Watch.
