Zenith 16520 daytona.

Hi guys, need some advice. seen a 16520 that looks cosher . on the 4030 movement where it says "ROLEX" the number underneath is 34351. does anyone know if this would be correct. Should it relate to the serial number on the casing (between the lugs). Thanking you in advance,

Every Rolex movement has its own unique movement number, and has nothing to do with the case serial number or clasp bracelet number.

Thanks for that Peter. dont suppose you know if a 16520 circa 1993 with the 4030 movement could have been fitted with "el Primero" rotor instead of a "Rolex" rotor. someone once speculated that when built sometimes the el primero was fitted. cheers.
