Zenith has always been one of the most innovative brands in the pantheon of Swiss watchmaking greats. To begin with, it was founded in 1865 by Georges Favre-Jacot to, for the first time, unite the varying cottage industries that littered the towns and hillsides of the Swiss Jura under one roof. Zenith is also famed for, in most eyes, emerging victorious in the race to create the world’s first automatic chronograph — when, in 1969, it unveiled the El Primero, a dazzling, industry-leading chronograph. It was the first of its kind, being an integrated automatic chronograph, and boasted prestigious high-performance features such as a column wheel, lateral coupling and a fast-beat escapement. This movement was replete with staggering innovations — not the least of which was its 5Hz vibrational speed, where the super-fast escapement wheel had to be lubricated with a special in-house-developed paste as normal oils would not hold.
