Zenith El Primero Surf Chronograph R.01.0210.415 While this automatic valjoux based timepiece is a “secret Daytona”, this chrono is strong on its own as it oozes with character and is from the 1970s. Service history is unknown but keeping time—Winds smoothly and chronograph starts, stops as it should but resets to approx 58sec which is common for vintage and do not recommend adjustment as it can easily start stop back to zero (12).
