You’ve probably never heard of Nappey or the Jumelles Times (“Twin Time”) watch, and for good reason: It was an obscure model in the 1960s that went nowhere. But the idea of a watch with multiple dials showing different timezones has become a common complication today. And it all came from this watch!
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.
