Zenith El Primero Chronomaster Power Reserve

REF : 18.2080.4021/01.C494

Often acclaimed as the world’s most precise chronograph featuring lavish ornamentation and exquisite designs, Zenith El Primero is the only chronograph movement which permits a short-term measurement of 1/10 seconds. The combination of stainless steel, 18k rose gold and argente or black dials is beautifully highlighted by the wide range of brown leather or stainless steel bracelets. El Primero, in its many interpretations, is the first watch in the world with a movement beating at a high rate- 36,000 vibrations per hour, while a traditional movement is set at 28,800VPH.
