To support seventh edition of the Only Watch charity auction, Zenith has created a unique edition of the Defy El Primero 21 timepiece. It features a new 1/100th of a second chronograph and two completely independent movements, each driven by its own regulator. The 44 mm black DLC titanium case and signature yellow details on the dial make the Defy El Primero 21 a highly attractive, unique piece, further emphasized by the presentation box which has been exclusively designed for this watch.
Launched at Baselword 2017, the Defy El Primero 21 is a masterpiece of modern engineering. Constructed using state-of-the-art methods and finished using the newest technologies and materials, the Defy El Primero 21 fulfils two objectives: a finish of the highest possible quality, and optimum performance and precision on the wrist. First released in 1969, the world’s most accurate series-made chronograph entered a whole new era of mechanical timekeeping with the Defy El Primero 21. An impressive frequency of 360,000 beats per hour is testament to the groundbreaking ingenuity of Zenith, and enables precise measurement of time periods to a hundredth of a second. The jump from tenths to hundredths of a second is a quantum leap in terms of watchmaking performance and engineering.
Alongside the double-chain structure of the caliber, and the remarkable precision this ensures, the El Primero 21 boasts other technical highlights: a new, patented start/stop/reset mechanism composed of three heart pieces, and an exclusive starter mechanism which ensures reliable operation under all circumstances, and allows all chronograph displays to be simultaneously reset.In addition, the springs in both regulators are fully carbon; more specifically created from the ultra-light and incredibly stable carbon nanotube metal matrix composite. This world first ensures that the Defy El Primero is unaffected by magnetic fields and temperature changes as well as the influence of gravity.
This watch is a unique combination of materials and colors, boasting a powerful 44 mm black DLC titanium case and a black alligator leather strap featuring yellow stitching detail and lined with rubber. The double folding clasp holds the watch securely and elegantly on the wrist. The caseback is specially engraved and the sapphire crystal bears the logos of Only Watch and the Monegasque Association against Muscular Dystrophy.
