El Primero, developed by Zenith from the well-established brands of the watch industry and known as the world's first automatic movement with chronograph feature, is under the spotlight once again with the Zenith Defy El Primero 21 Black Ceramic (Ref. 49.9000.9004/78.M9000).
The model we have here from the Zenith Defy El Primero 21 Collection for review, presented to the watch enthusiasts at the Baselworld 2017 exhibition is the Ref. 49.9000.9004/78.M9000 with skeleton dial and black ceramic case (and bracelet).
The model is offered in a black ceramic case measuring 44m in diameter and 14.5mm in height. Equipped with double anti-reflective treated scratch resistant sapphire crystals on both sides, the case is water resistant to 100 meters / 10 bars.
“The model’s skeleton style dial offers a matching stance with the all black concept while not scarifying the legibility.”
The hour and minute markers are clearly applied on an outer chapter ring around the dial. There is a linear crescent-shaped power reserve indicator at 12 o’clock right above the Zenith and El Primero 21 texts. The sub-dials are placed in 3-6-9 Tri-Compax layout and accompanied with a center mounted chronograph second hand. Thanks to the Super LumiNOVA phosphor fillings (in matching black with the concept) on the hands and indices, sufficient legibility is provided in dark environments.
The model is powered by the Caliber El Primero 9004, which opens the doors of the 21th century to the El Primero Collection. Self-winding movement beats at 36000vph. The interesting part is this 36000vph movement sports a chronograph module that beats at 360000vph. Shortly named as the 5Hz + 50Hz system, the key feature of this concept is the double chain design. The movement includes two different systems with their own balance wheels, gear trains and mainsprings. More importantly, it can display 1/100th measuring chronograph readings on an analog lay-out.
Zenith Defy El Primero 21 Black Ceramic (Ref. 49.9000.9004/78.M9000) comes on a bracelet manufactured from the same black ceramic material like the case. There are also a pair of strap options available in the collection as a black rubber strap and a black alligator strap with vulcanized rubber lining.
We would like thank Konyalı Saat family once again for their utmost support and cooperation.
