Zenith Chronomaster El Primero Grande Date Full Open
The timepiece is a self-winding skeleton-worked chronograph, equipped with a column wheel and a silicon escapement, highlighted by a dial carved in sapphire. This modern architecture with its striking red accents is designed to be admired from both sides.
Playing on transparency
For a watch that has a sophisticated technical nature, transparency is a boon. How else would the watch entice the wearer into the very heart of a cutting-edge Zenith mechanism? The timepiece is a very sturdy stainless steel chronograph. The 45 mm-diameter case is water-resistant to 100 metres. The domed crystal on the top and the sapphire crystal case-back ensure a double sided view. It reveals on both sides the outlines of an in-house ‘engine’ with legendary origins.
The crystal-clear sapphire dial features two transparent blue and grey-tinted counters, the aesthetic signature of the original 1969 model. It also shows the moon and the sun phases on twin discs at 6 o’clock. A silver-toned inner bezel ring surrounded by a blue ring, a black and white minute scale, along with luminescent facetted hands and hour-markers, all contribute to ensuring optimal legibility, yet without obscuring the view of the fascinating inner workings. The large date at 2 o’clock – shown by two concentric discs with cut-out numerals – is read off against a bright red background in an engraved aperture, while the slim red-tipped central sweep-seconds hand adorned with the emblematic Zenith star sweeps over this perfectly clear display.
The El Primero integrated automatic column-wheel chronograph beats at the fiery pace of 5 Hz, thereby ensuring and displaying 1/10th second precision. These sterling attributes are inherited from its illustrious predecessor, the world’s most accurate series-made chronograph developed by Zenith and presented in 1969. The high-frequency oscillations of El Primero Calibre 4047B are indeed a thing to talk about!
The watch is enhanced by a steel bracelet or a black leather rubber-lined strap. Another version is available with a two-tone exterior (stainless steel case with a pink gold bezel), teamed with a chestnut leather strap.
The Zenith Chronomaster El Primero Grande Date Full Open is impressive indeed!
