The Zenith Defy El Primero has been given the honor of being dubbed the "21st Century Chronograph." With its immensely impressive 1/100th of a second chronograph hand, it is very easy to see why. It stands as proof that watchmaking is alive and well today! This watch is a certified chronometer with two escapements. One for the main movement and another entirely for the chronograph. The ceramic case, rhodium plated hour markers and hands, are excellent compliments to the beautiful open-worked dial featuring gorgeous blue highlights. This example includes the watch, outer box, inner box, travel case, booklets, cleaning cloth, and USB stick. Asking $6969 The watch will be shipped, overnight, fully insured, with signature required, as soon as funds clear. As for myself, I have many references from buying and selling across the various forums, Reddit, WUS, TRF, etc. I would be willing to provide upon request. Feel free to reach out to me with any questions and I will do my best to answer! Thanks for looking and feel free to follow me on IG for more! @the.apex.co

Zenith SA is a Swiss luxury watchmaker. The company was started in 1865 by Georges Favre-Jacot at the age of 22, in Le Locle in the canton of Neuchâtel. Zenith was purchased by LVMH in November 1999, becoming one of several brands in their watch and jewellery division. Jean-Claude Biver became Interim CEO in 2017, replaced CEO Aldo Magada, who replaced Jean-Frédéric Dufour in 2014.

Zenith has a long reputation for the quality and precision of their watches. It is one of the Swiss watch manufacturers that still produce their own movements in-house.

The El Primero calibre, which was first released in 1969, and still produced today, was one of the first automatic chronograph movements and has a frequency of 36,000 alternations per hour (5 Hz). This high rate allows a resolution of 1⁄10 of a second and a potential for greater positional accuracy over the more common standard frequency of 28,800 alternations per hour (4 Hz). The El Primero was honoured with a 2012 release of the El Primero Stratos Flyback Striking 10th, limited to 1,969 pieces (in honour of the original 1969 release date), that housed the same 36,000 vph movement and a sub-dial measuring in tenths of a second to make a complete rotation every ten seconds.
