Heuer made quite literally hundreds of different and unique stopwatches during its storied history, with one of these being the near new-old stock (NOS) 1980s Heuer Ref. 3073 Microsplit Digital 1/100,000 stopwatch here, with its original Heuer box.


The Microsplit is a unique specialized industry timer that measures to the decimal, per hour – it is not a 60 second timer – and surprisingly, there is next to no evidence of use on this Heuer Microsplit.   It measures 1/100,000 hour up to 9.99999 hours, with start, stop, time-out, split and reset-to-zero functions.  Heuer advertized quartz accuracy of +/-0.0004%, with battery use of longer than two years.

Eduard Heuer founded the Heuer Watch Company in 1860 in St. Imier, Switzerland.  In 1911, Heuer introduced the first automobile dashboard chronograph called the "Time of Trip."  This timepiece revolutionized the world of automotive racing because it enabled the pilots and co-pilots to keep track of their lap times. In 1914 they changed the sports world once again with the introduction of the first wrist worn chronograph. 


Heuer’s dominance of the stopwatch market continued into the 1970s and 1980s, when electronic stopwatches finally dethroned them.


This Heuer Microsplit comes with its original Heuer-signed lanyard.
