Zenith was founded in the year 1865 on the initiative of Georges Favre-Jacot as “Fabrique des Billodes”. In the year 1911 the company was converted into a limited company. The name Zenith dates back to the following incident: One evening, Georges Favre Jacot had just developed a watch which seemed more perfect to him than all the previous ones. As he looked up at the clear night sky, these celestial mechanisms appeared to him like the play of the wheels and cones of the watch and he decided to name his watch after the highest point on the Universe: Zenith. He therefore chose a five star as a company logo. On 10th January of the year 1969, after two years of development, Zenith introduced the first automatic stop watch El Primero with 36000 half oscillations per hour and thereby won the prestigious race over the companies such as Breitling and Hamilton-Büren. „The El Primero “is today considered as the most popular work of its class; it is comparable to the works of Lemania 5100 and Valjoux 7750 of ETA due to its high frequency of 36 ' 000 half oscillations per hour (corresponding to 5 cycle per second, usually 21600 and 28800 half oscillations per hour, thus 3 or 4 cycles per second) and its superior high production quality. In 1994, elite, the extra-flat automatic mechanism was introduced; it underlined the status of the brand as one of the few genuine watch makers. Since 1999, Zenith together with the Brands, TAG Heuer and Chaumet belonged to the French LVMH group.
Defy Xtreme open. As a top sports watches line, Zenith has surpassed itself: the results are unexpected aesthetics, avant-garde technology and a unique style. The DEFY XTREME OPEN is the chronograph of the future: thanks to the combination of titanium, Kevlar, TR90 and the new alloy Zenithium, it is unbreakable and waterproof up to 1,000 M. The product, a 4021 SX, was redesigned, in order to also meet the demanding needs. Power, masculinity, modern appearance - with this watch, one lives on the fast lane.
