Zenith El Primero Class 4 Mens Automatic Chronograph, Stainless Steel - 02.0500.400


Item No. 5716

Today's offering showcases this very cool Zenith Class El Primero with original bracelet. Its display back design showcases the beauty and precision that distinguish its legendary El Primero movement.

One of the finest automatic chronograph movements ever produced, when it was introduced in 1969, it became the world's fastest beating chronograph movement, beating at a speed of 36,000 vibrations per hour, and set a new standard against which other high-end, professional chronographs were judged, and continues to be produced today.

Here are some of the watch's features:

  • "Iin house" caliber 400 movement - after almost forty years, the El Primero remains unmatched in its ability to measure short time intervals to one-tenth of a second
  • High frequency 36,000 beats per hour balance system, twice the speed of many traditional chronographs and faster than any other chronograph in existence, insures exceptional accuracy
  • Very legible and well executed matte black dial with large luminous markers and hands
  • Full size 39mm case and substantial steel bracelet. We love the case bracelets feel - they feel very solid without yet aren't overly heavy on the wrist. The case is a nice size - it's full size yet looks and feels less bulky than many other automatic chronographs.

We are proud to offer it in gorgeous condition - about a 9.7 out of 10. On the wrist it presents as nearly like new with very slight signs of polishing. One section of wording on the case back is light, although still fully visible. Its El Primero movement is running strong and true and all the chronograph hands reset smoothly to a perfect zero very time.

Its accompanied by its original boxes. Included with the purchase is a one-year C.O.T. international warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate attesting to its performance.
