Although unconventional time displays are popular today, very few watches had so-called retrograde hands to display the time until the 1990s. Sector displays first appeared in pocket watches as early as 1650 and were wildly popular in the early 1900s thanks to the Sector pocket watch from Record. But it was not until the Le Phare Sectora, LIP Secteur, and Wittnauer Futurama of the 1970s that this complication appeared on the wrist. These watches are rarely seen or discussed today, but were truly groundbreaking even as the quartz revolution challenged watchmaking.
Given the clever retrograde chronograph movement, the Gran’Sport Chronograph is the pick of the Gran’Sport lineup today. It’s really too bad that gorgeous Reverso Chronographe Rétrograde is out of the price range for most people.
