Zenith ChronoMaster Collection, Edition 2009

Timeless in style, this collection, with its subtle Italianate overtones, threads its way between Tradition and Modernity. This icon of the ZENITH Manufacture, inspired by the neoclassical, is a celebration of Time. From the double gaudron case to the authentic barleycorn guilloche, it has a look that harks back to the great watchmaking tradition. Its boldly innovative design allows the 36,000 vibrations per hour of the mythical El Primero chronograph to be glimpsed at the heart of the movement.

This collection, timeless yet strikingly modern, which now joins the Haute Horlogerie universe along with the ChronoMaster Open Grande Date Moon & Sunphase, has been enriched with new complications over the years, thus writing new chapters in the history of the ZENITH brand.

Zenith ChronoMaster Open

The ChronoMaster Open matches the watchmaking tradition with modernity, ZENITH uncovers the heart of Time and reveals the 36,000 vibrations per hour of the legendary El Primero chronograph through the opening in the dial. This will be the first Open El Primero 4021 calibre.

The impertinence of the collection is creating a stir in the watchmaking world. The applique numerals, the double gaudron of the case, the black alligator strap are the signature features of a new elegance.

The range is available in two sizes (45 mm and 40 mm), in rose gold with a silver guilloche or stainless steel dial or alternatively in stainless steel with a choice of dial in black or silver, with a smooth or guilloche finish. A revolutionary technology allied to a daring design – this collection is reasserting its distinguished and ambitious style.

Zenith ChronoMaster Open Grande Date

In 2008, this collection was endowed with a new fully-mastered complication, the ChronoMaster Open Grande Date. This innovative timepiece stands out because of its design as well as its sophisticated technical features.

The three patented disks for the Grande Date at 2 o’clock can be seen as a result of the outstanding transparency of the dial. This translucent and unbreakable material – the result of space research – lightens the perspective, making it seem as though the numerals are floating.

The opening on the dial at 10 o’clock, the emblematic symbol of the range, reveals the El Primero 4039 movement composed of 331 components and 41 rubies. The appliqué Roman numerals and barleycorn guilloche dress the dial which comes in rose gold for a classical look or stainless steel for a more contemporary design.
