Zenith

Began in 1865, Georges Favre-Jacot, pioneering the modern "manufacture" by uniting watchmaking trades under one roof for quality control, earning numerous chronometry awards for precision. Key milestones include the 1909 "Pilot" trademark, the 1948 Calibre 135 chronometer, and its legendary 1969 El Primero automatic high-frequency chronograph, saving the brand during the quartz crisis. Now part of LVMH, Zenith remains a leader in high-frequency watchmaking, known for innovation and its association with aviation and record-breaking achievements, notes Monochrome Watches and Zenith Watches.
