Zenith Defy Skyline Chronograph Metallic Black – 03.9500.3600/21.I001

Architectural, geometric and intricately faceted, the DEFY Skyline’s 42mm steel case is a modernized take on the earliest DEFY’s octagonal case with a multi-sided bezel. Retaining the same DNA of robustness and durability as its predecessors while bringing an edgier and more contemporary aesthetic. In the DEFY Skyline Chronograph, the pushers follow the sharply drawn lines of the case, while the screw-down crown emblazoned with the star emblem helps ensure a water-resistance of 100m. 
Available in metallic black, blue or silver, the DEFY Skyline Chronograph’s dial pairs the collection’s signature starry sky-patterned dial featuring engraved four-pointed stars with the traditional El Primero dial configuration. Three slightly oversized and overlapping counters show the elapsed seconds and minutes of the chronograph, as well as the constant running seconds. The date window – matching the color of the dial – is positioned at 4:30, another El Primero signature. The flange ring with the 1/10th of a second scale has twelve facets, the form of the dodecagonal bezel and serving as extensions of the hour markers.
In an ever-faster moving world, every fraction of a second counts. Just like in the DEFY Skyline automatic model and its skeleton counterpart, ZENITH continues to offer the 1/10th of a second function in the DEFY Skyline Chronograph. This mechanical feat is the result of the El Primero 3600 calibre’s high-frequency rate of 5Hz (36,000 vibrations per hour), visible through the display back. Its open star-shaped oscillating weight with bidirectional winding efficiently provides a power reserve of 60 hours.
One of the highlights of the DEFY Skyline is its integrated quick strap-change mechanism integrated directly into the case, allowing for effortless versatility without requiring any tools. With the simple push of a button, the three-link steel bracelet can be swapped with the supplied star-patterned rubber strap with steel folding buckle.
