Embodying the philosophy of absolute performance, the Zenith Star Open pays tribute to the El Primero calibre. Right at first glance, this model draws the gaze to the expressive strength of its original cushion shape accentuated by an opening at 10:30 revealing the legendary heart of the mechanical automatic movement, El Primero Calibre 4062. This window onto the escapement thus shows the intricate inner workings of the movement: the high frequency is no longer an abstract principle, since one can actually keep track of the oscillations and see the watch beating. In order to avoid hiding this technical feat from view, readability is the keynote of the dial, which indicates the hours and minutes in the centre, while the small seconds appear in a heart-shaped display at 9 o’clock.The central chronograph hand and the 30-minute counter at 3 o’clock further enrich this harmonious visual symphony. The mother-of-pearl or guilloché dial, depending on the model, emphasises the desire to achieve aesthetic perfection in each and every detail, as also exemplified in the blue Roman numerals or faceted rhodiumed hands that match the intense blue of the elegant cabochon-cut sapphire adorning the crown. Governed by the unshakeable conviction that the true perfection of a work of art is perceptible in its smallest details, the movement decoration is visible through a sapphire case back.

Three models are available: a steel version set with 28 VVS brilliant- cut diamonds totalling approximately 0.17 carats; a rose gold version set with 63 VVS brilliant-cut diamonds totalling approximately 0.27 carats; and a rose gold version set with 263 VVS brilliant-cut diamonds totalling approximately 1.57 carats. They are fitted with an alligator leather strap complete with a triple folding clasp. These Zenith Star Open watches represent exceptional creations that clearly already belong to the heritage of a brand that fully dedicates its outstanding expertise to the pursuit of precision, elegance and performance.

There appears to be no stopping the mechanical automatic ultra-thin Zenith Elite 692 movement, housed in this instance within the remarkable cushion-shaped case of the Zenith Star Moonphase model. The epitome of slenderness at just 3.87 thick, it comprises 195 parts, beats at a frequency of 28,800 vibrations per hour and drives a display of the over 50-hour power reserve. It highlights a superb mechanical movement by endowing it with a technical and aesthetic dimension.The stage is superbly set for the hours, minutes, small seconds and moon phase appearing on the silver-toned dial. The latter marks off the hours and minutes on blue Roman numerals matching the deep blue shade of the exquisite cabochon-cut sapphire set on the crown. This superbly modern and distinctively elegant model gives pride of place to the functions: the small seconds indication at 9 o’clock, and the moon-phase display at 6 o’clock entirely dedicated to the path of the nocturnal luminary. On the back of the watch, a sapphire crystal reveals the intricate workings of a hand-decorated and engraved movement. Offering a splendid expression of horological refinement, this watch comes in a choice of steel or rose gold set with 28 VVS brilliant-cut diamonds totalling approximately 0.17 carats, fitted with an alligator leather strap complete with triple folding clasp. Whichever the version, it consistently offers its wearer the pleasure of reading off a time that is truly unique.
