Zenith Port-Royal Grande Date El Primero watch

The Zenith Port-Royal Grande Date El Primero watch is an appealing intersection between horological substance and sophisticated aesthetic design. With its elegant, rectangular form, refined dial detailing, and exclusive Zenith manufacture mechanical chronograph movement, this timepiece presents a nearly irresistible combination to watch lovers. Measuring 51 x 36mm in diameter, the stainless steel case of the Zenith Port-Royal Grande Date El Primero watch shows off a finely polished finish that evokes an aura of luxury and masculine confidence. A close examination of each detail reveals the importance Zenith places upon exceptional attention to fine processing and hand finishing. This quality is also shared by the stunning dial with its window-pane guilloche central section, matte outer section with printed Arabic numbers, and chronograph subdials with their fine concentric circle motifs.

The Zenith Port-Royal Grande Date El Primero watch utilizes a self-winding mechanical movement which is celebrated as one of the finest chronograph calibers ever created. First introduced by Zenith in 1969, the El Primero movement represented a technical benchmark that still stands today--a fully integrated, column-wheel controlled automatic chronograph mechanism with a balance wheel beating at the unheard of rapid pace of 36,000 alternations per hour; this latter detail enables the chronograph to offer precision chronograph timing corresponding to 1/10 of a second.

The movement inside the Port-Royal Grande Date watch is designated as the El Primero 4010 caliber, and offers connoisseurs the additional technical element of a large date display. This elegant date display, which relies upon two discs, is easily read as well as a fine example of superior mechanical engineering. The inscription "chronometer" upon the dial affirms the passage of 15-days of exacting tests by the Controle Officiel Suisse des Chronometres (C.O.S.C.), where the movement has undergone demanding examinations of its precision under various temperatures and positions. The aesthetics and intricate mechanism of the 4010 caliber movement can be admired fully through the exhibition sapphire caseback. This Zenith watch is available with either a sand-colored or anthracite dial. Both versions are supplied with a strap in alligator leather or rubber with a triple deployant clasp. A stainless steel bracelet is optional.
