Zenith Grande Class Grande Date El Primero watch

The Zenith Grande Class Grande Date El Primero watch is a luxury timepiece that embodies style and substance equally. Classic yet extremely confident, this Zenith timepiece bears a rich heritage of horological craftsmanship and know-how that has given this brand a highly respected place amongst prestigious Swiss watch manufacturers. Crafted from premium stainless steel which has been impeccably finished, the 44mm case of the Grande Class Grande Date El Primero watch frames a strikingly clean black dial with applied polished Arabic numerals, silvered chronograph subdials, and a silver framed window for the large date display. The elegant domed profile of the scratch-resistant sapphire crystal merges seamlessly with the gently sloped bezel, contributing to the harmony and grace of the Zenith Class watch design.

Despite its understated aesthetic, the Zenith Grande Class Grande Date watch is an eloquent statement of the watchmaker's art. Within the stainless steel case resides a famous Zenith manufacture movement---the El Primero 4010 caliber. Like the original Zenith El Primero chronograph movement from 1969, this exclusive self-winding caliber offers a fully-integrated chronograph mechanism which is controlled via a column wheel. The most distinctive feature to this finely engineered movement however, is its uniquely rapid balance wheel frequency of 36,000 alternations per hour. Thanks to this exclusive detail, the El Primero chronograph can measure short term intervals with precision to 1/10 of a second.

Zenith submits each of these movements to the Controle Officiel Suisse des Chronometres (C.O.S.C.) where each earns a chronometer certificate only after passing 15 days and nights of rigorous tests in various positions and a range of temperatures. Depending upon whether the owner desires a casual or dressy appearance, the Zenith Grande Class Grande Date El Primero watch is available on either a rubber strap signed with the Zenith star, a hand crafted alligator strap, or an intricate 5-link stainless steel bracelet. The versions on strap are joined to the wrist via a triple deployant stainless steel clasp.
