This is a stunning example of a Zenith El Primero Ref. A3817. This watch was produced in 1971 in only a reported 1000 examples, and is housed by Zenith’s legendary and groundbreaking automatic chronograph El Primero movement. The tri-color dial and hands are in stunning condition. The case has been polished, but very slightly.
This is truly an amazing and classic watch, adorned and respected by virtually all collectors.
