Zenith Chronomaster Open Grande Date

Playing shade against light, the extraordinary design of this watch perfectly illustrates the fusion of Tradition and Modernity. The cloisonné guilloche dial, appliqués and sword-shaped hands that sing the praises of the great classics, are transcended by resolutely modern touches.

On the dial, subtly smoked cut-outs give a transparent effect, allowing a glimpse of the pearly plate beneath and the 3 patented discs of the Grande Date. Finally, the opening in the dial, so symbolic of the design, reveals the new complication, the El Primero 4039 movement, and shows us the mystery of time.

This timepiece is endowed with more than one radiant face. The rose gold cases offer silver dials whilst the stainless steel cases have either black or silver versions.

They are available in two sizes, diameter XT –45 mm or T –40 mm, and are dressed with a new integral alligator strap to produce a more contemporary line with maximum comfort.
