Item No. 4170

Today's offering features an original Movado Datron wristwatch, one of the finest automatic chronograph wristwatches ever produced. It's El Primero movement, which required seven years of R & D, set the standard against which high-end, professional chronographs were judged for decades. Filled with revolutionary new technology, it left a legacy that is still influencing the modern idea of the luxury chronograph today.

So superior is this fine mechanism it was also called upon to direct renowned watches like the Panerai Luminor and the Rolex Daytona which was still utilizing it into the twenty-first century!

Here are a few of its features:

  • After almost forty years, the El Primero remains unbeaten 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
  • Full 50 hour power reserve
  • Very efficient automatic movement with 360 degree, ball-bearing supported rotor to keep the watch wound on the wrist
  • Large rugged and waterproof case with screw back
  • Quick-set date mechanism for more convenient date setting
  • Masculine blue dial with tachometer scale

With the exception of the crown, which appears to have been replaced at some point, this watch remains in original condition and shows honest wear. Included with the purchase is a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.
