Defy El Primero 21 Ultrablue 44 mm, stainless steel with blue rubber strap, self-winding caliber El Primero 21 with chronograph function | Reference Number ZN100014

Stop the time to 1/100th of a second? No problem with the high-frequency chronograph Defy 21 Ultrablue (Ref. 97.9001.9004/81.R946), which houses a dual architecture inside, which in itself is a fascinating highlight. The self-winding chronograph movement El Primero 21 beats at a frequency of 36,000 vibrations per hour to display the time, while the additional and separate chronograph mechanism beats at an incredible rate of 360,000 vibrations per hour and enables the exact stopping to the hundredth of a second. Although the movements with their violet hue can be admired without obstacles through the skeletonized dial and sapphire crystal caseback, the wheel responsible for the blazingly fast seconds hand is barely visible to the naked eye due to the speed of its movement. A 44-millimeter matte titanium case and two rubber straps in blue and black complete the sporty, technical design of this watch, which is water-resistant to 100 meters and with which Zenith has set a milestone among self-winding chronographs of the 21st century.
